MISSION STATEMENT

The Metal and Nonmetal National and Regional 

Contests serve as training tools to improve the skills 

required to respond to a mine emergency. These 

competitions serve to strengthen cooperation between

GENERAL RULES

FOR CONDUCTING THE CONTEST

 1. The National Contest will be comprised of four 

individual events, including a Mine Rescue Field 

Competition (two days for each participating 

team), a Technician Team Competition, a First Aid 

Competition, and a Team Trainer Competition. 

Each event will include a written examination. 

Note: Regional Contests will include the same 

four individual events; however, the field 

competition may be limited to a one day event.

 2. Contest officials will be comprised of the Contest 

Director, Contest Coordinator, Chief Judge, 

Appeals Committee, field competition judges 

(including: field judges, mine managers, and 

mine attendants), isolation officials, written exam 

judges, technician team contest judges, and first 

aid contest judges.

 3. There will be no limitations as to the number of 

teams admitted from any county, state, district, 

company, or organization.

 4. All teams must actively provide bona fide mine 

rescue services for the metal and nonmetal 

mining industry and meet all of the requirements 

set forth in 30 CFR Part 49. Collegiate mine 

rescue teams may compete in any or all of 

the competitions with approval of the Contest 

Director. If a collegiate team competes in all 

competitions, they must meet the requirements 

listed in General Rule No. 5.

 5. Mine rescue teams may register a minimum of 

six and a maximum of eight competing team 

members. The team may also register a team 
2

trainer. If the team trainer competes in any one 

of the competitions, he/she must be included as 

part of the 8-member team. For the purpose of 

technician team and first aid contests, a team 

member may not participate in more than one 

event and each team will only be permitted to 

compete in each event once. The technician 

teams must compete with the same type of 

breathing apparatus and multi-gas instrument 

that their teams will be using for the mine rescue 

field contest. For the purposes of identification, 

participants of the Mine Rescue Field, Technician 

Team, and First Aid Contests must be dressed 

uniformly, complete with team logo. This includes 

the testing process. Once registered, no changes 

will be permitted without the permission of the 

Contest Director.

 6. A schedule of Regional Contests and the 

National Contest, as well as the respective 

hosting organizations, will be posted on MSHA’s 

homepage under the “Mine Rescue” heading at 

www.msha.gov. The specific contest entry forms 

may be obtained through the hosting organization.

The entry forms will require information regarding 

the type of equipment (breathing apparatus) each 

team will be wearing, the type and model of all 

gas testing equipment the team will use during the 

field competition, and the type of communication 

system to be used. Any needed equipment 

changes require submission of a modified list to 

the Contest Director for consideration of approval. 

(Note: Each judge will be given a list of your 

equipment prior to working of the problem to 

assist them in determining if the equipment was 

utilized properly and was functional.)
3

 7. On the day before the contest begins, team 

equipment shall be secured in isolation and team 

registration will be conducted at a designated 

location. Afterward, all of the written tests 

(outlined in this booklet) will be administered in 

isolation. For planning purposes, the hosting 

organization will prepare a contest agenda to 

include: a specified time period for equipment 

drop-off; a specified time period and location 

for team registration; and a listing of scheduled 

events for the rest of the week. The agenda will 

be provided in advance to all participating teams 

and contest officials. At the time of the contest, 

the agenda will be posted in various locations as 

a reminder for all.

8. On the day before the contest begins, all written 

tests will be administered in isolation. The team 

members (Nos. 1 – 7) and team trainers will 

be directed to sit at separate tables. Persons 

from the same company or organization will 

also be required to sit apart from each other at 

the designated tables. A separate area will be 

designated for additional team alternates (No. 8) 

who wish to take the test(s). Their tests will not 

count toward their cumulative team scores.

Note: No wireless communication or electronic 

device will be permitted in isolation or during the 

written testing.

The field competition, first aid, technician team, 

and team trainer tests will be included at this 

same time. A description of each test with 

the corresponding references is listed in the 

respective section of this booklet. A total of 60 

minutes will be allowed to complete all required 

testing. At the end of the allotted time, tests will 
4

be collected regardless of whether or not the 

contestants have answered all of the required 

questions.

 9. For the National Contest, the team drawing 

will be conducted as each team drops off their 

equipment in the isolation area. As each team 

arrives, the number selected by the team captain 

will determine their running order for the first day’s 

field competition and the third day’s first aid and 

technician team competitions. On the second 

day of the field competition, the teams will run in 

reverse draw order.

For Regional Contests, a similar team drawing 

will be conducted. However, the number selected 

by each team captain will determine their running 

order for the one-day field competition. Then, the 

teams will run in reverse draw order for the first aid 

and technician team competitions. 

In both cases, position changes necessary for 

management of the respective contest will be 

permitted if the Contest Director approves the 

change.

10. On every day of the competitions, all teams shall 

be in isolation at a time designated by the Contest 

Director. No wireless communication or electronic 

device will be permitted in isolation. Any team 

member found with a wireless communication or 

electronic device in isolation will result in the entire 

team being disqualified.

11. All judges will be persons trained in mine rescue 

procedures; trained in the assembly, use, and 

care of the different types of breathing apparatus; 

and trained in the assembly, use, and care of 
5

the different types of multi-gas instruments. The 

judges will not be connected with any of the teams, 

teams’ employers, or companies who manufacture 

apparatus or gas detecting devices. Exceptions to 

personnel assigned for judging any phase of the 

contest require the approval of the Contest Director.

12. ...WARNING... Any team whose member(s) 

intentionally disturb or destroy any component on 

a competition field will immediately be assessed a 

100 point discount. Repeated offense may result in 

team disqualification at the discretion of the Contest 

Director.

13. For Regional and the National Mine Rescue 

Contests, the hosting organization will supply one 

person per field during the mine rescue field and 

first aid competitions. These persons will act under 

the direction of the field coordinators and will be 

used as survivors or patients, respectively. 

When an approved 4-hour oxygen breathing 

apparatus and/or an approved 1-hour oxygengenerating self-contained self-rescuer unit is 

required to be used on a patient, the team must 

demonstrate proper donning procedures and unit 

activation. 

After acknowledgement by the judge, for an 

approved 4-hour oxygen breathing apparatus, the 

breathing hoses can be disconnected and the unit 

turned off. The breathing apparatus must be kept 

in close proximity (as if it were used) to the patient 

during transport out of the mine. 

For an approved 1-hour oxygen-generating selfcontained self-rescuer unit, a training model may 

be used during the competition.
6

14. A trophy will be awarded for the Overall Mine 

Rescue Contest Champion based on the 

best cumulative team scores (least amount of 

discounts), including the combined discounts for 

the mine rescue field, first aid, and technician 

team competitions. In the event of a tie, the 

team with the best mine rescue team standing in 

the mine rescue field competition will be the tie 

breaker.

15. The results from all elements of the National and 

Regional Contests will be distributed to the teams 

at the conclusion of the awards ceremony.

8

will be determined to be incorrect by the test 

judge and discounts assessed.

 2. Scoring of the test will be completed by at least 

two qualified judges.

 3. In special circumstances, individual team 

members may be given an oral test by one or 

more judges in lieu of a written test. Requests for 

consideration shall be presented to the Contest 

Director at the time of registration. All other team 

members will take the test at the same time. In 

any case, the judges will not explain the meaning 

of questions, but may explain a word or words in 

the questions.

 4. One trophy will be awarded for the Team Trainer 

Competition. The team trainer with the least 

amount of discounts on the written test will be the 

winner. In the event of a tie, the team trainer with 

Overall Mine Rescue Contest Champion Team 

will determine the winner. The second tie breaker 

would be the team trainer with the best mine 

rescue team standing in the mine rescue field 

competition.

MINE RESCUE FIELD COMPETITION

GENERAL RULES

 1. The Contest Director will establish a reasonable 

amount of time for each team to complete the 

problem(s). All teams will be notified of the 

established time prior to beginning to work the 

problem(s). Any teams working beyond the established time period will be notified by the #1 

Judge that they must leave the field. All teams 

will be scored based on their discounts, including: 

appropriate discounts for items missed in areas 

left unexplored or abandoned by the team; and

appropriate discounts for necessary actions not 

taken by the team to complete the mission.

 2. The Contest Director will ensure that all field 

problems are designed so that a team can 

successfully complete each problem with no 

discounts.

 3. Discounts will not be added to the team’s field 

score once the judges have signed their discount 

sheets. This does not preclude changes due to 

administrative errors or a misapplication of a rule.

 4. ... WARNING ... Any team whose member(s) 

intentionally disturb or destroy any component on 

a competition field will immediately be assessed a 

100 point discount. Repeated offense may result 

in team disqualification at the discretion of the 

Contest Director.

 5. Upon completion of the problem, a 5-minute 

review will be conducted regarding their working 

of the problem. At that time, the team will be 

informed of infractions and will be permitted 

to verbally appeal these with the field judge or 

the chief judge. If not resolved, the chief judge 

will make the final decision until an appeal can 
10

be filed by the team. Note: During this process 

mutual respect for the judges and team members 

is paramount and civility must be demonstrated 

by all involved or the review will be stopped 

before the allotted time.

 6. After the scorecards are checked by the 

scorecard examiners, they will be taken to a 

designated location. At a designated time, the 

team captain, trainer, and one other team member 

may examine their team’s scoring cards for a 

time not to exceed 20 minutes. A schedule will 

be posted near the 20-minute look location. No 

protest of the discounts assessed may be given to 

the person in charge of the review, however, the 

team captain and/or trainer may protest in writing 

any discount within 30 minutes after reviewing 

them. Written appeals are not to exceed one page 

for any discount assessed and will be submitted 

to the Appeals Committee.

Documentation (contest rules and other 

documents used in the contest) supporting the 

appeal will be accepted. Any protest(s) will be 

considered by the Appeals Committee. A discount 

summary sheet will be used to list the discounts. 

All discounts except time will be listed and totaled. 

Both the captain and the review judge will sign the 

team discount summary sheet to certify they have 

reviewed the discounts and verified the totals 

(See page 60).

 7. The Appeals Committee shall rule in matters 

concerning any interpretations, procedures, 

or any matter involving proper conduct of the 

Contest. Any complaints filed with the committee 

shall be in writing and shall set forth incidents, 

times, names, source of information, and the act 

complained against. Where a written test question 
11

or rule application was found to be wrong, all 

teams will receive the appropriate correction. A 

decision by a majority of the committee shall be 

binding.

 8. A predetermined amount of trophies will be 

awarded for the Mine Rescue Competition based 

on the best cumulative team scores (least amount 

of discounts). For the National Mine Rescue 

Contest, this would include each team’s combined 

discounts for both day’s field problems plus their 

written test discounts. For the Regional Contests, 

this would include each team’s discounts for the 

field problem (one-day event) plus their written 

test scores. 

In the event of mine rescue field competition ties, 

the underground discount sheet will be the first 

tie breaker, the surface discount sheet will be the 

second tie breaker, mine maps will be the third 

tie breaker, the written test will be the fourth tie 

breaker, and time will be the fifth tie breaker.

GUIDELINES AND PROCEDURES

Team Members

Each team shall be composed of five members, one 

fresh air base attendant and one assistant (optional). 

Each member shall wear a number on the arm at or 

near the shoulders with number one (1) being assigned to the captain, the number six (6) to the fresh 

air base attendant and seven (7) to the assistant. 

Switching of numbers by team members will not be 

permitted after arriving at the portal or fresh air base. 

Any means of affixing legible numbers on the sleeve 

of the uniform will be acceptable. Additional persons, 

who had been isolated with the team, may assist the 
12

team placing equipment prior to starting the clock. 

Only the fresh air base attendant and the assistant 

will be allowed to assist the team after the clock has 

started. The fresh air base attendant and assistant will 

be isolated from visual contact with the field while the 

teams are in the mine. The fresh airbase attendant will 

maintain voice communications with the team utilizing 

a portable communication system. The team may use 

either one of the following options to accomplish this 

task. 

 1. Teams will be equipped with and use a portable, 

hard wire, communication system. The wires or 

cable shall be of sufficient tensile strength to be 

used as a manual communication system. Teams 

may use standard signals if the communication 

system fails. The assistant may listen in with a 

separate headset and advise the fresh air base 

attendant and interact with the team only when 

they are at the fresh air base. If during the working 

of the problem any team member is unable to 

continue (due to physical condition or by problem 

design), the assistant (No. 7 member) may be 

used as a substitute. The team can rearrange 

member positions to complete the problem.

 2. Teams may use a wireless communication system 

(radios), provided they are designed and used in 

such a manner that the integrity of the Contest 

is not jeopardized, as determined by the Contest 

Director. A lifeline will still be required for working 

of the problem. This can be achieved through the 

use of a wire or cable which has sufficient tensile 

strength to be used as a manual communication 

system. The assistant may listen to the radio 

transmissions and advise the fresh air base 

attendant and interact with the team only when 

they are at the fresh air base. If during the working 
13

of the problem any team member is unable to 

continue (due to physical condition or by problem 

design), the assistant (No. 7 member) may be 

used as a substitute. The team can rearrange 

member positions to complete the problem. 

Note: For teams using a wireless communication 

system (radios), the specific requirements for 

use are outlined in the “Equipment” section.

In either case, teams wishing to communicate with the 

fresh air base attendant shall use their portable communication system, or they must return to the fresh air 

base. 

Medical Requirements

Per 30 CFR Part 49, all mine rescue team members 

must have completed physical examinations in the 

past 12 months preceding the contest and are capable of performing strenuous work under oxygen. 

Equipment

Breathing apparatus approved for at least four hours

shall be used in the Mine Rescue Contest problems. 

Each team member must have his/her own approved 

breathing apparatus. Teams cannot expect recharging materials, apparatus parts, and accessories for all 

types of apparatus at the contest site. 

Team members must wear an approved protective 

hat, identification tag, safety shoes, permissible cap 

lamps, self-rescuer, and be clean shaven to the extent 

that a good face-to-facepiece seal is achieved. 

Each team must have approved gas instruments, or 

testers for rescue and recovery work. 

Teams are required to bring with them a sufficient 

supply of materials. Brattice or other materials necessary for constructing bulkheads or stoppings will 

be furnished by the field committee. Teams will be 
14

responsible for collecting the material from the source 

of supply. 

When teams report to the fresh air base to begin the 

problem and are given information indicating that 

explosive gas(es) is/are or may be present in the 

mine, they must have non-sparking tools while they 

are working the problem so as not to endanger themselves. If teams do not have non-sparking tools, they 

must ask the official in charge at the fresh air base to 

provide them with such tools before they go underground. 

If the mine is not classified as gassy and the teams 

go underground to work the problem and encounter 

an explosive gas and they do not have non-sparking 

tools, they must return to the fresh air base immediately and ask the official in charge to provide them 

with such tools.

For teams who opt to use a wireless communication 

system (radios) during the mine rescue field competition, the following procedures shall be strictly followed. 

• All radios are to be MSHA-approved and

intrinsically safe. 

• Upon completing the contest entry form, the 

team shall properly identify that they will be 

using radios in lieu of a hard-wired system 

during the field competition. 

• On the day before the contest as the team 

drops off their mine rescue equipment, they 

must provide all of their radios to the 

official-in-charge with a list of the programmed 

channels and frequencies. The radios must be 

properly labeled as team property so that they 

can be stored exclusively for the respective 
15

team’s use. The associated charger(s) must be 

supplied.

• Teams using wireless communication must have 

radios charged and properly programmed to the 

MSHA FCC licensed radio frequencies prior to 

turning them over to contest officials.

UHF radios must support at least 16 channels 

(see Table 1).

VHF radios must support at least 3 channels 

(see Table 2).

• MSHA licensed radio frequencies and settings 

such as PL codes, low power, and narrow 

banding protect MSHA and teams from FCC 

violations and prevent crosstalk between competing teams.

• When selecting a channel for team competition, the team’s radios will be set by a designated contest official on a channel that is 

different from any other radios in use.

• The mine manager or other designated contest 

official will check and monitor conversations 

on the channel selected. In the event of failure 

of the radio provided to the mine manager or 

other contest official, corrective actions will be 

immediately taken by the team.

• Teams may take up to three radios inby the 

fresh air base and must provide at least two 

for the fresh air base to be used by the team’s 

attendant and the mine manager or other 

designated contest official. Teams may leave 

additional radios at the fresh air base for use 

in case of malfunctions. A minimum of three 

radios shall remain operational during the 

working of the problem. This consists of: 

one radio each for the team underground, the 

team’s fresh air base attendant and the mine 

manager or other designated contest official. 

This complement of radios is necessary for the 

team to be considered as using wireless communication. 

Team Preparation (Apparatus) 

Team members must make necessary checks of all 

apparatus for proper working condition and airtightness prior to going underground. Cylinder pressures 

must be within specifications of approval. Apparatus 
17

tests must comply with prescribed tests for that particular type of apparatus. 

An approved 4-hour oxygen breathing apparatus and/

or an approved 1-hour oxygen-generating unit must 

be used as an emergency spare for a mine rescue 

team member or for use on the survivor(s) or other 

rescued personnel when respiratory protection is 

needed. 

Note: If a survivor is found and is wearing an approved 1-hour oxygen-generating self-contained selfrescue (SCSR) device, the team will not be required 

to replace it with one of the above mentioned units 

unless the SCSR has been depleted. In addition, if 

any of the above persons are unconscious, an approved 4-hour oxygen breathing apparatus equipped 

with a full face-piece must be used.

Written Test

On the day before the contest begins, all written tests 

will be administered in isolation. The mine rescue field 

test will be included at this same time. Team member 

Nos. 1 through 7 will take the written test. The six best 

test scores (least amount of discounts) will be counted 

as the team’s cumulative written test discounts. If 

the team does not have a No. 7 alternate, then the 

aggregate sum of scores for team member Nos. 1 

through 6 will count as the team’s cumulative written 

test discounts.

The questions for the written test will be taken 

from material contained in MSHA Publication 3027 

– Instructor’s Manual for Mine Rescue Training 

(formerly MSHA Publication “IG 6”). The training 

modules in Publication 3027 are as follows: Module 

1 – Surface Organization; Module 2 – Mine Gases; 

Module 3 – Ventilation; Module 4 – Exploration; 
18

Module 5 – Fire, Firefighting, and Explosions; Module 

6 – Rescue of Survivors and Recovery of Bodies; and 

Module 7 – Mine Recovery.

MSHA Publication 3027 is available on the MSHA 

homepage at http://www.msha.gov/MineRescue/

E-mail:MSHADistributionCenter@dol.gov

The written test of thirty (30) questions will include at 

least ten (10) questions on mine gases from MSHA 

Publication 3027 (Module 2 – Mine Gases) for each 

team member. The questions shall consist of true/

false and multiple choice questions.

The total written test discounts will be included as part 

of the team cumulative discounts for the mine rescue 

field competition (i.e., National Contest – two-day total 

or Regional Contest – one-day total).

Judges

All judges will be persons trained in mine rescue 

procedures and knowledgeable in the rules, interpretations, and the procedures for working the respective 

problems. The judges will attend training sessions 

prior to the contest concerning the problems to be 

worked and the guidelines for working such problems. 

Judges will be trained in all aspects of the problems to 

allow for consistent and accurate judging.
19

Competing teams deserve the full attention of the 

judges and only those personnel judging the specific 

teams are allowed on the field. While the team is in 

the mine, judges must not ask questions, answer 

questions, or interfere with the team. Only personnel 

approved by the Contest Director will be permitted on 

the field. Media access and videos for future training 

aids will be allowed with the Contest Director’s 

approval.

During preparation, judges are to observe the captain and other team members as to their knowledge 

and proper operation of the self-contained breathing 

apparatus, gas detecting devices, other respiratory 

protection equipment to be used, and firefighting 

equipment, etc. 

The mine manager will be stationed and must remain 

at the fresh air base when the teams are working the 

problem. He/she will provide answers, as necessary, 

to questions posed by the team, the fresh airbase 

attendant, or the assistant.

A minimum of two (2) persons will judge the team 

during the entire working of the field problem. Only 

the Contest Director, Chief Judge, or their designee 

may discuss discrepancies or discounts on the field. 

If discussions are held on the field, interrupting the 

working of the problem, the time will be stopped and 

restarted after the discussion is over. A Mine Safety 

and Health Administration employee will be the #1 

Judge. All judges must have current Mine Rescue 

Judge’s Training and have been briefed on the particular problem and possible solutions. 

The judges will mark and explain on their scorecards 

the discounts for work performed by each team 

member. In the event that more than one discount 

applies, the highest discount will be assessed for 
20

a violation. There will be no stacking of discounts. 

Judges must sign their scorecard after the discounts 

have been recorded. Scorecards will be marked 

promptly and delivered to scorecard examiners as 

soon as possible after completion of the problem. 

Security

Each team must be under guard before the start of 

the contest, in a location assigned by the Chief Judge, 

and must remain continuously under guard until time 

to work the problem. Any team receiving information 

concerning a contest problem will be disqualified. No 

person except guards and contest officials authorized 

to do so will be allowed to communicate with any 

team or teams under guard. Teams that have performed will not be permitted to communicate with any 

teams awaiting their turn to perform.

Only judges, contest officials, escorted photographers, 

and news media approved by the Contest Director 

will be permitted on the competition fields. A separate 

area will be provided for spectators to observe the 

teams during competition. 

Competition Problem

The problem may involve a multi-level mine; however, 

the team will be limited to working on one level. It 

may include hoists or shafts. Skip pockets and sumps 

(either above or below) will be considered part of 

the working level. Raises or boreholes may be in the 

problem; however, climbing will not be required. 

Teams may have to change existing ventilation, pump 

water, or move falls to rescue persons and/or explore 

if it can be done safely. Changing ventilation shall not 

be done until the official in charge has been informed. 

Ventilation changes will be considered as starting, 

stopping, altering, or redirecting the air current. If 
21

existing check curtains are to be used to direct ventilation, the check curtain must first be converted into 

a temporary stopping. Regulating airflow to control a 

fire is not considered a ventilation change. 

All areas that have been cleared of smoke and toxic 

or dangerous gases that the teams elect to travel 

through must be rechecked prior to the team’s 

reentering. Upon re-entry into these areas where the 

ventilation has been changed, whether advancing or 

retreating through these areas, separate gas tests will 

be conducted by the team along the route they travel 

across each entry (rib-to-rib) within 25 feet of each 

opening to the place turned off the entry. 

When smoke or gas is encountered in an opening, it 

will be considered to extend to the next placard indicating the smoke or gas is cleared. 

If water is being pumped, ventilation changed, falls 

moved, loose rock barred down, etc., teams must wait 

until placards have been changed by the ground committee. If placards have not been changed after 15 

seconds, teams must assume that their actions were 

not successful.

Inaccessible areas only need to be explored when 

there are miners unaccounted for or if an explosive 

air/gas mixture will be moved through the unexplored 

areas. Therefore, teams will not be required to set 

timbers or pump water until all accessible areas have 

been explored and there are still missing miners. 

Teams will not be considered unsystematic if these 

conditions are found and passed during initial exploration of the problem field. When it becomes necessary 

to explore inaccessible areas, appropriate materials will 

be provided. 
22

Only judges, contest officials, escorted photographers, 

and news media approved by the Contest Director or 

Chief Judge will be permitted in the working areas. 

Insofar as possible, materials rather than placards will 

be used in the mine. Bodies with identification may be 

designated by the use of dummies. When placards indicating conditions are used, they will be placed face 

up, and the letters shall not be less than one (1) inch 

in height, and easily visible. 

Additionally, when these placards are used to identify 

mining machinery or equipment, a description of the 

current condition of the equipment and/or a photocopy 

of a picture of such machinery or equipment may be 

on the placard, when possible, to aid teams in identifying it. 

Terms used in the problem will be terms which appear 

in the Glossary of this Rule Book, the MSHA Mine 

Rescue Training Modules, or 30 CFR Part 49 and 

Part 57. 

When raises, winzes or boreholes are in the problem, 

the card identifying them will indicate whether they go 

up and/or down from the level being worked. 

TEAM PREPARATION AND PROCEDURES 

Apparatus and Material Checks 

Before reporting to the contest field, each team 

member must check his/her own apparatus to see 

if it is charged properly and in good working condition. These checks must be within the manufacturer’s 

specified limits and the regenerator fully charged with 

chemicals.
23

Other materials such as roof testing devices, stretchers, hammers, blankets, fire extinguishers, and gas 

detectors must be checked to see that they are in 

good operating condition. If horns are to be used for 

signaling between team members, they should be 

checked. A portable communication system, utilizing insulated wire strong enough to give and receive 

manual signals, must be used by all teams. Wheeled 

stretchers will be allowed. 

Briefing

When all members of the team have their apparatus 

fully assembled and ready to wear, the captain should 

assemble the team and report to the Briefing Station 

Official when directed by the guard. The team will be 

briefed on field conditions either by a video or a briefing paper. Team members will return any handouts 

at the conclusion of the briefing. The briefing should 

contain all pertinent information, including the following conditions: classification of the mine; frequency of 

explosive gas being found; accuracy of the mine map; 

possibility of the mine being cut into another mine; 

condition of the fan; have guards been posted; electric 

power cut off from the mine or affected parts of the 

mine; recovery work that has been accomplished; 

notification of the local, state, and federal agencies; 

reserve rescue teams, equipment, and materials that 

are available. 

Any final adjustments to the equipment and necessary 

talks between team members can be completed prior 

to reporting to the field judge. 

Reporting to Field 

On reporting to the field, communication cable can be 

strung out prior to starting the clock. Afterward, the 
24

captain should have the team line up at the place indicated by the person in charge. The captain introduces 

his team and remarks “We are here to offer our help. I 

have a fully equipped, properly trained, and physically 

fit mine rescue team and we are ready to do anything 

that you may require in the rescue and recovery work 

at your mine.” The official in charge will reply that they 

do require the service of mine rescue teams, and that 

if they are ready, they can be of immediate service. 

Start of Problem

When the necessary introductions have been made, 

the team captain will indicate that they are ready for 

the problem and map. No work will be done until the 

clock is started. The captain will start the timing device 

and date the board (month, day, year, and team position number) before receiving the problem and the 

map. After the clock is started, only the five working 

team members, fresh air base attendant, and assistant 

will be permitted to do the work at the fresh air base. 

MSHA’s field attendants will feed out and reel in the 

communication wire. 

The fresh air base attendant will receive the problem 

and map at the same time. From this point on, the 

team members should discuss the conditions presented by the problem and the map. On the map, solid 

lines will denote actual workings. Although locations 

may not be totally accurate within the six (6) foot map 

requirement, solid lines will represent known conditions. Dotted lines will denote projections and may 

or may not be accurate. These conditions should be 

studied carefully so that proper procedures may be 

decided in advance. 
25

Equipment Checks and Procedures 

No testing of equipment is required at the fresh air 

base. Testing of equipment used by the team will be 

performed while the team is in isolation before reporting to the field. This testing will not be judged; however, 

if any defects occur while working the problem, discounts will be assessed. Random checks of equipment 

to ensure reliability may be made upon completion of 

the problem. 

Standard Communications and Signals

A portable communication system, utilizing hard 

wire, will be used to inform the fresh air base of all 

conditions encountered. External speakers will not 

be permitted at the fresh air base while working the 

problem. In the event of a communication failure, the 

team will be required to return to the fresh air base to 

repair or replace the system. 

The following standard horn blasts or other audible 

signals between team members will be used:

1 blast on the horn will mean for the team to 

“stop” if in motion

2 blasts on the horn will mean “advance”

3 blasts on the horn will mean “retreat”

4 blasts on the horn will mean “distress” 

Hoist Signals 

The following signals will be used for the Mine 

Rescue Field Competition. The conveyance shall 

not be moved without a command signal: when 

persons are to be hoisted or lowered, they must enter 

the conveyance and close the door; then give the 

signal for the desired level followed by either “Hoist 

Persons” (3-1 bells) or “Lower Persons” (3-2 bells). 
26

9 Bells: Emergency - then ring mine level signal where 

emergency exists.

Team Safety 

Team members must follow established procedures, 

per this booklet for the type of equipment used, when 

getting under oxygen. 

The team captain must now check each member’s apparatus. A team member must make the same checks 

on the captain’s apparatus. The judges will observe the 

operation and adjustment of the apparatuses. 

The captain should see that the team line is properly 

stretched out and that the team members are holding 

or are attached to the team line. 

If a team encounters smoke, an apparatus check or 

personnel check is required before entering smoke. 

The captain must now have the team count off either 

orally or visually by the raising of hands. In smoke, all 

team members must have hold of, or be fastened to, a 

lifeline. 
27

The captain must give the signal to advance. The 

stretcher bearers should pick up the stretchers, and 

the rear captain shall relay the signal to the fresh air 

base. When the signal is returned, the team may now 

advance into the mine. 

Entrances to all mine openings shall be examined while 

under oxygen. In air clear of smoke, these checks may 

be made without a lifeline, provided the entire team 

does not go into the entrance. This examination should 

not cover more than twenty-five (25) feet.

For Contest purposes, a placard denoting “clear air” 

will mean that the atmosphere is free of smoke and all 

dangerous and/or harmful concentrations of flammable, combustible, noxious, and/or toxic contaminants.

Teams shall never travel through water over knee 

deep.

Checking for loose ground (loose roof or rib) is done 

visually by the team captain as the team advances. 

The captain must verbally indicate that he is checking 

for loose ground at every location required. The team 

captain must orally warn the team each time loose 

ground conditions are encountered. A similar warning 

must be given upon retreat. 

First Team Stop

After advancing into the mine, not more than fifty (50) 

feet from the cage or portal, the captain shall give a 

signal for the team to stop. The co-captain may take 

no more than two steps forward after the signal before 

stopping. The captain now checks the members and 

their apparatus to see if they are in good condition and 

a team member checks the captain and his/her apparatus. (This check must not be made on the cage.) The 

procedure shall be followed at not more than twenty 

(20) minute intervals while the team is working the 
28

problem. Additionally, apparatus removed in order to 

enter a confined area or apparatus that has sustained 

possible damage from impact must be checked before 

continuing. 

If all the apparatus are operating properly and the 

members are in good condition, the team can now 

continue into the mine. 

The cage door must be closed and the signal to 

release conveyance to a standby mode must be sent 

after the cage has been unloaded. 

Advancing 

When stops are made at the openings of crosscuts, 

intersections, or drifts turned off the drift that is being 

traveled, separate gas tests must be made across 

each entry (rib-to-rib) within 25 feet of each opening 

to the place turned off the entry. No place, which 

intersects entry direction, should be passed without 

first checking the condition of that place. Examination 

of any intersection or entry shall not exceed 25 feet 

from the rear captain. This means the captain can 

extend out into openings and take gas readings within 

the limits of the team line. 

In case of entries turned from the entry being traveled, 

it is a matter of choice which entry is to be followed 

and many things must be taken into consideration 

in making the choice. However, the openings of all 

places must be checked before that place is passed. 

A team will be considered to have passed an opening 

or intersection when the number 5 member is past the 

opening. 

While advancing, if a team encounters an impassable 

fall or other condition that prevents the members from 

following the normal course of travel into an area, they 

may break a stopping and enter that area. If it becomes 
29

necessary to break a stopping, the team shall erect a 

temporary stopping or stoppings that would have the 

same effect on the area that the original stopping would 

have provided. 

Doors shall not be opened without prior knowledge 

of the effects of the mine ventilation system, unless 

a temporary stopping has been erected. However, in 

any case, if the conditions behind the stopping or door 

are unknown and there is a potential that missing miners are located in the enclosed area, these ventilation 

controls should be treated like a “barricade” and the 

same precautions must be taken as prescribed in the 

section below.

Regulators shall not be opened without prior knowledge of the effects of the mine ventilation system, 

unless a temporary regulator has been erected. 

Where crosscuts are blocked, no team member may 

advance more than three (3) feet beyond the second 

(2nd) intersection before tying across and/or behind 

into all unexplored areas that intersect. The second 

intersection will be determined by two crosscuts on 

either side of the entry being traveled. The first intersection will be the blocked intersection. However, a 

team will be permitted to tie across to adjacent drifts 

to tie in behind.

Barricades 

If a barricade is found, the team will take action to protect the barricaded persons as indicated by the conditions found outside the barricade. For the purposes of 

contest work, no barricade will be breached without 

ventilating in front of the barricade if an Immediately 

Dangerous to Life or Health (IDLH) atmosphere is 

present, including: Oxygen (O2) is below 17.0%; or 

Carbon Monoxide (CO) exceeds 1200 ppm (0.12%); 
30

or Hydrogen Sulfide (H2S) exceeds 100 ppm (0.01%); 

or Nitrogen Dioxide (NO2) exceeds 20 ppm (0.002%); 

or Sulfur Dioxide (SO2) exceeds 100 ppm (0.01%); or 

Carbon Dioxide (CO2) exceeds 4.0%. In the event that 

gases other than these are encountered or indicated 

by the problem, the team must ask for stain tubes 

or testing devices for these gases if they don’t have 

them.

If conditions behind the barricade are unknown, the 

barricade cannot be breached unless the team erects 

a reasonably airtight temporary stopping. The space 

between the barricade and the temporary stopping 

should be as little as feasible; however, it should be 

large enough for the team to enter. When entering the 

barricaded area, the opening in the barricade should 

be kept to a minimum, the roof in the area shall be 

tested, and gas tests made. 

If survivors are found and conditions warrant (i.e., 

survivor will travel through an IDLH atmosphere), they 

shall be given proper respiratory protection which can 

include an approved 1-hour oxygen generating unit. If 

a survivor is unconscious, an approved 4-hour oxygen 

breathing apparatus equipped with a full face-piece 

must be used. 

Note: If a survivor is found and is wearing an approved 

1-hour oxygen-generating self-contained self-rescue 

(SCSR) device, the team will not be required to 

replace it with either a 4-hour or a 1-hour oxygen 

generating self-contained self-rescue unit unless the 

SCSR has been depleted. 

If more than one (1) survivor is behind the barricade 

and proper protection cannot be provided for all of 

them, the team in retreating should keep the openings 

in the barricade and temporary stopping to a minimum 

so that as little irrespirable air will get into the barricade 
31

as possible. If the area beyond the last survivor can be 

explored without advancing the survivor, this should 

be done before retreating with the survivor. When all 

the survivors have been removed from the barricaded 

area, the enclosure may be opened (or breached) as 

wide as necessary for easy exit. Survivors must be 

secured to the stretcher and covered with a blanket 

unless first aid procedures indicate other treatment is 

proper. If a person is found behind a barricade or in a 

refuge chamber and the area is not entered, the team 

may advance beyond the chamber for exploration. 

However, if survivor(s) can be safely evacuated without 

changing conditions, they shall be evacuated before 

any further exploration is done. 

Dates and Initials 

The date and the captain’s initials must be marked at 

the point of farthest advance of the team in any direction such as at stoppings, faces of rooms and drifts, 

water over knee deep, impassable falls, barricades, 

fires out of control, and at the location of any survivors 

or bodies. The captain must verbally indicate to the 

judges each time initials and date are simulated. 

Maps and Timing Device

The map person and fresh air base attendant must 

use the standardized map legend provided in this rule 

booklet. If a symbol is not available on the legend, 

the team must write out the exact information contained on the placards on both maps. Teams will be 

expected to accurately map all required items on the 

maps maintained by the team and the fresh air base 

attendant.

An additional map will be provided to the team for use 

by the team alternate, if they so choose. However, 

deficiencies found on this map will not be counted 

toward the team’s cumulative score.
32

After the team has completed its 50 foot check, they 

will not be allowed to physically compare the team 

map with the fresh air base map. That is, no side by 

side comparison will be allowed and no changes 

(edits) can be made to either map while the team is at 

the fresh air base or out of the mine. When the team 

has explored all accessible areas, accounted for all 

miners and completed all required work, they should 

return to the fresh air base and count off. At that time, 

no other changes can be made to either map and the 

captain should present all three maps to the person in 

charge of the mine and stop the timing device. 

The marked maps must show: the condition of all 

faces, stoppings and doors; the location of all placards 

or materials; the location of fires and barricades; and 

the location of dead bodies and survivors (including 

identification). Temporary stoppings that are erected 

shall also be shown as well as the location of any gas 

found or indicated by placards. The maps must show 

all locations dated and initialed by the team captain. 

If a team fails to explore the entire mine, the furthest 

point of advance shall be indicated on the maps by a 

line drawn across the entry with the appropriate mine 

map legend symbol. 

Ventilation

Under no circumstances should mine ventilation 

be altered without knowing the full effects of those 

changes and without notification of the changes to 

the mine manager.

A contaminant or explosive gas, when indicated on 

a placard and regardless of the mass, is considered 

moved throughout the established ventilation course 

until exhausted from the mine. 
33

Unless otherwise documented by placards indicating 

air movement, the mine is not considered to have 

natural ventilation or airflow. All airflow is provided 

by the existence of mine fans or other mechanical 

ventilation. However, before the team can breach, 

open, or alter an existing ventilation control (bulkhead, 

door, stopping, or regulator) without the knowledge of 

the effects on the existing mine ventilation system, the 

team must follow the necessary precautions outlined 

in the “Advancing” section of these rules.

Ventilation changes will be considered as starting, 

stopping, altering, and/or redirecting the air current. 

The direction of airflow depends upon where the team 

constructs ventilation controls. A standard brattice 

frame and curtain are 10 feet. Therefore, if the team 

elects to build a ventilation control at a distance 

greater than 10 feet, such as diagonally across an 

intersection, they must utilize a second brattice frame 

and curtain. 

If existing check curtains are to be used to direct ventilation, the check curtain must first be converted into 

a temporary stopping.

Regulating airflow to control a fire is not considered a 

ventilation change.

If there is no clear air separation, indicated by placards, 

stoppings, caved air tight, the entire area is considered contaminated. Once the team has established an 

airflow course, areas that contain contaminants that 

are not directly in the established air course, and have 

two or more openings, could potentially be drawn from 

those areas unless isolation and/or ventilation controls 

are established to prevent movement. An example is 

in an uncontrollable fire area where regulators were 

constructed. Until all but one regulator is closed, airflow 

will draw from those regulators into the established air 

course.
34

Blankets or other porous materials cannot be used as 

curtains to direct airflow. All brattice material, including 

wing curtains, will be provided for each problem so 

that adequate ventilation can be established to work 

the problem correctly. Teams need not carry additional 

brattice materials on their stretcher. 

All problems will be designed with at least one clear 

and systematic ventilation solution. When the team 

alters and/or constructs ventilation controls, and the 

effects of those changes do not clear the air and the 

placards do not change, the team has missed a critical adjustment to the ventilation solution.

Mine Fires 

When a mine rescue team encounters a noncombatible fire, indicated by “intense heat” or “fire out 

of control,” the team shall, without undue delay, seal 

the fire or regulate the fire, so as to restrict the air flow 

to the fire and prevent its further advance. Regulating 

airflow to control a fire is not considered a ventilation 

change. The team must then, without undue delay, 

find all other approaches to the fire and seal or regulate them. This does not preclude systematic exploration of the area. Whether to use regulators to control 

the fire or to entirely seal the fire must be decided by 

the team. The team must inform the official in charge 

prior to making any ventilation changes. This decision 

will take into consideration the safety of the team and 

any survivor(s), the classification of the mine (gassy/

non-gassy), the presence of any explosive gases, 

the possible effects of any ventilation change(s), and 

other pertinent data. A regulated fire, left unsealed, 

has the potential to emit contaminants into the mine 

atmosphere.
35

Roof or Ground Control

The following illustration (Figure 1) shows the proper 

method of setting roof supports through an unsafe 

area using the safe ribs as support. 

• 5-foot maximum spacing between temporary 

roof supports. 

• The first support is set a maximum of 1 foot 

from the area designated as unsafe. 

• The rib can be used as support unless designated as unsafe. 

• Once a post has been set to correct and support an unsafe roof condition, it cannot be 

removed.

If the unsafe roof is less than 5 feet in length, a minimum of three supports must be set; one on each end 

and one under the unsafe roof.

The team must simulate setting support and then 

place placard (or other material provided by the contest officials) on the floor in the proper location.

(See Figure 1 on next page)

and one under the unsafe roof. 

The team must simulate setting support and then place 

placard (or other material provided by the contest officials) on the floor in the proper location.

 Note: If the team decides to travel through the intersection to the east or the west, additional supports will 

need to be installed (as shown in green on the illustration).
39

Figure 4

The following illustrations (Figures 4 and 5) show the 

proper method of setting roof supports to recover a 

patient located under an area of unsafe roof or back.

roof supports. 

• The first support is set a maximum of 1 foot

from the area designated as unsafe. 

• Once a post has been set to correct and 

support an unsafe roof condition, it cannot be 

removed.

If the unsafe roof is less than 5 feet in length, a minimum of three supports must be set; one on each end 

and one under the unsafe roof. 

In each situation, the team must simulate setting supports and then place placards (or other material provided by the contest officials) on the floor in the proper 

location.
40

Figure 5

Note: If the miner is alive and requires first aid, 

additional supports will need to be installed (as shown 

in green on the illustration) so that additional team 

members can safely access the area and provide 

necessary treatment.
41

Gas Field Testing

Gas testing proficiency will be conducted during 

the working of the mine rescue field competition. At 

the fresh Air Base, the team will find a gas box (gas 

cylinder and tubing) containing an “unknown” mixture of gases. Each mine rescue team will need to 

provide their own calibration cups for their multi-gas 

instruments and will be expected to report all required 

concentrations within acceptable limits: O2, CH4, CO, 

and NO2.

This segment of the contest will be scored by the 

judging officials as follows: at each gas box, there will 

be fifteen (15) discount points deducted per gas if the 

team does not report the respective gas concentration 

within the acceptable limits below:

 a. Oxygen readings are considered to be correct if 

within plus or minus 0.5% by volume;

 b. Methane readings are considered to be correct 

if within plus or minus 0.2% by volume (LEL 

readings are not acceptable) with an instrument 

equipped with a catalytic sensor. Note: For those 

instruments equipped with an infrared sensor, 

the readings would be rounded to the nearest 

whole number. Therefore, a team must use an 

instrument equipped with a catalytic sensor in 

order to be within the required tolerance;

 c. Carbon Monoxide readings are considered to be 

correct if within plus or minus 10% of the actual 

value present; and

 d. Nitrogen Dioxide readings are considered to be 

correct if within plus or minus 3 ppm of the actual 

value present.

 lowered to the level to be explored, then raising 

 it to the collar.

 2. not having non-sparking tools in a gassy mine 

 or when explosive gases are found in a non-

 gassy mine.

 3. changing conditions of the mine ventilation 

 system in such a manner that an explosive 

 mixture is moved over an ignition source. 

 Changing conditions of the mine ventilation 

 system in such a manner that an explosive 

 mixture is moved over an unexplored area. If a 
50

 team explores all sides of an overcast or an 

 undercast, both ends of a ventilation shaft, or 

 the top and bottom of shafts when the shaft 

 cannot be traveled, the in-between areas are 

 considered explored for ventilation purposes.

 4. continuing exploration after conditions are

 found to indicate an imminent explosion is 

 possible by the presence of an explosive mixture 

 and the evidence of fire (smoke or carbon 

 monoxide) and the location of the fire is unknown. 

 A team must continue to explore if it knows there 

 is a continuous nonexplosive separation between 

 the explosive mixture and the evidence of fire.

5. utilizing electric or battery-powered equipment 

 in explosive air/gas atmosphere. Ignition sources 

 would include any communication device, unless

 designated as sound-powered or intrinsically safe. 

 6. failure to take a functioning wire communication 

 system into the mine or committing an act that 

 causes the communications system to break or 

 fail while underground.

 7. removing a post that has been set to correct and

11. This will be assessed for not exploring all areas of 

the mine that can be explored without endangering 

team, if problem requires entire mine to be explored. 

All accessible areas must be tied across and behind 

before advancing. Where crosscuts are blocked, no 

team member may advance more than three (3) feet 

beyond the second intersection before tying across and/

or behind into all unexplored areas that intersect. This 

may require building an air lock or returning to the fresh 

air base and exploring into other drifts at the discretion of 

the team and according to conditions of the mine. Shafts 

must be checked for possible damage, water, or fire, and 

must be traveled to be considered explored. All shafts 

must be traveled, if possible, before proceeding more 

than three (3) feet beyond the second intersection. 
51

12. Personnel checks, not necessarily an apparatus check. 

The person making the check must obtain assurance 

from person being checked that he/she is all right 

(asking if person is okay will suffice).

13. Sealing or fighting a fire does not relieve the team of 

the responsibility of systematic exploration.

18. An act which does not endanger the team, but may 

injure or result in the death of a survivor. Some 

examples of this would be:

a. Breaching a barricade with an IDLH atmosphere 

 outside

b. Directing an IDLH atmosphere over survivor(s) 

 through a change in ventilation

c. In the case of multiple survivors, leaving the higher 

 priority patient and taking a less injured patient out

d. Improperly protecting survivor(s) from an IDLH 

 atmosphere

e. Continuing exploration beyond a miner (potential 

 survivor) who is clearly visible to the team and 

located under unsafe roof after an adequate supply 

 of roof support materials have become available 

for his/her safe recovery (applies to similar areas 

 as shown in Figure 1 through Figure 5 under the

MINE RESCUE DISCOUNTS AND INTERPRETATIONS 

Underground Interpretation 

Judge #2 

 1. Tests for gases must be made at face areas, stoppings, 

doors, regulators, barricades and other areas where 

conditions are unknown. When stops are made at the 

openings of crosscuts, intersections, or drifts turned off 

the drift that is being traveled, separate gas tests must 

be made across each entry within 25 feet of the rear 

captain’s position. No place shall be passed without first 

checking the condition of that place. That is, if a room 

is turned from the entry, that room shall be checked 

before examining the entry beyond the opening. This 

does not necessarily hold true in cases of entries. In 

cases of entries turned from the entry being traveled, it 

is a matter of choice which entry is to be followed and 

many things must be taken into consideration in making 

the choice. However, all places must be checked before 

that place is passed. A team will be considered to have 

passed an opening or intersection when the No. 5 

member is past the opening. All areas that have been 

cleared of smoke and toxic or dangerous gases that the 

teams elect to travel through must be rechecked prior 

to the team’s reentering. Upon re-entry into these areas 

where the ventilation has been changed, teams shall 

make gas tests (rib-to-rib) at all openings along the 

route they travel.

 2. This will depend on type of instrument used. Improper 

procedure when testing includes the location of the 

instrument when testing or using a gas detection 

device beyond its limits or range. For example, a 

methane detector must be held overhead when testing 

because methane (CH4) is light and will be found in 

high places near the back or roof. Nitrogen dioxide 

(NO2) is relatively heavy and will be found in greater 

concentrations along the floor and in low places. 

Therefore, this test must be made with the tester below 

the waist. Carbon monoxide (CO) is slightly lighter than 

air so this test must be made at chest height. 
58

 3. Self-explanatory.

 4. Self-explanatory.

 5. This does not apply to checking mine entrances prior to 

working the problem.

 6. Teams traveling obviously faster than a normal walk 

(both judges must concur on this) shall be discounted.

 7. Do not hesitate to assess this discount; however, 

explain and name unauthorized person on discount 

card and state instructions given, if known.

 8. Self-explanatory.

 9. The No. 5 member may move from side to side to give 

captain more area when team is connected by lifeline 

in smoke or by communication line as long as he/she 

does not pull or give line. All team members must hold 

or be attached to the lifeline at all times while traveling. 

If taglines are used between team members and the 

team line, they shall be no longer than 3 feet in length.

10. Stoppings, doors, regulators, and barricades require 

construction of temporary stoppings by a team before a 

team may make openings in the pre-existing stoppings, 

doors, etc. Doors shall not be opened without prior 

knowledge of the effects of the mine ventilation system, 

unless a temporary stopping has been erected. 

Regulators shall not be opened without prior knowledge 

of the effects of the mine ventilation system, unless a 

temporary regulator has been erected. This does not 

apply to existing check curtains used to direct the air 

current. When retreating out of a barricade or coming 

back through a stopping where an air lock has been 

erected, it will not be necessary to air lock on the way 

out, if this will not change any existing ventilation.

11. During a ventilation change, a curtain that directs 

airflow is required to be upgraded to a temporary 

barricade, seal, or stopping and must be fastened at 

top and sides.

12. Teams must inform the official in charge before 

changing the ventilation or electric power, and such 

things as explosive gases and the safety of trapped 

miners and rescue personnel must be considered. 

Teams do not have to exit the mine to change 

power or ventilation. Teams can inform the fresh air 
59

base attendant by approved communication devices 

available, and the fresh air base attendant must inform 

the official in charge before changing ventilation 

or electric power. Informing the official in charge of 

the fresh air base does not relieve the team of the 

responsibility of their decision.

13. Survivor must be secured to stretcher by at least two 

bandages or straps, one around trunk of body and one 

around legs, covered with blanket, and placed so as not 

to crimp air hoses. (Hands of unconscious person must 

be secured.)

14. This will be based on the Tenth Edition of Brady

“Emergency Medical Responder – First on the 

Scene”, Chapters: 3, 4, 6, 9, 10, 11, 12, 13, 14, 15, 

16, 17, 18, 19, 20, 21, 22, and 27, and MSHA 

Publication 3027 (IG 6) - Module 6, Rescue of 

Survivors and Recovery of Bodies. (This book may 

be ordered from the National Mine Health and 

Safety Academy. See page 18.)

15. To properly protect a survivor, a team must provide an 

approved 4-hour oxygen breathing apparatus and/or an 

approved 1-hour oxygen-generating unit. If a survivor 

is unconscious, an approved 4-hour oxygen breathing 

apparatus equipped with a full face-piece must be 

used. However, if a survivor is found and is wearing an 

approved 1-hour oxygen-generating self-contained selfrescue (SCSR) device, the team will not be required to 

replace it with one of the above mentioned units unless 

the SCSR has been depleted.

16. Applies to person sitting up unassisted or moving arms 

so as to help in putting on apparatus. (Only applies 

if person is member of the team and not an MSHA 

employee.)

TECHNICIAN TEAM COMPETITION

GENERAL RULES

 1. The Technician Team Competition will be held in a 

simulated mine rescue station and may consist of 

benching one self-contained breathing apparatus 

(which will be assembled) and at least one multi-gas 

instrument to ensure the field readiness of the team. 

Thus, with this practical approach at the conclusion 

of the competition, the technician team’s mine rescue 

team will be prepared to go underground and conduct a 

successful mine rescue mission. 

 2. The technician team will consist of two members of the 

8 person mine rescue team. Persons competing in the 

Technician Team Competition cannot be members of 

the first aid team.

 3. Registration will be made with the team registration.

 4. The Technician Team Competition will be held at 

designated location in conjunction with the first aid 

competition. Contestants will remain in isolation until 

they finish the Technician Team Competition or they will 

be disqualified.

team will be provided with one breathing apparatus 

(designated by each team at the time of registration) 

and at least one multi-gas instrument, equipment, tools, 

and supplies, as necessary to complete the problem. 

Only those tools, equipment, and supplies provided 

will be used by contestants to work the problem. It is 

imperative that each team provide the type and model 

of breathing apparatus that the team will be using 

during the field competition because the same type and 

model of breathing apparatus will be made available 

to the Technician Team at the “simulated mine rescue 

station” during the Technician Team competition. 
65

 8. Thirty (30) minutes will be allowed to complete the 

competition. There will be a five (5) minute warning 

given by the judge when the time is about to expire. If 

the technician team has not completed the competition 

when time expires, the judges will stop their activities. 

They will be scored based on their discounts to that 

point, including: appropriate discounts for items missed; 

and appropriate discounts for necessary actions not 

taken by the technician team to complete the assigned 

task. 

9. All defects in testing and preparation will result in the 

appropriate discounts.

10. ... WARNING ... Any team whose member(s) 

intentionally disturb or destroy any component on a 

competition field will immediately be assessed a 100 

point discount. Repeated offense may result in team 

disqualification at the discretion of the Contest Director.

11. When the 30-minute time limit expires, the judges will 

conduct a five-minute review of all discounts. After the 

review, both the judges and the technician team will 

sign the appropriate judge’s scorecard in the spaces 

provided. 

12. Only judges, contest officials, escorted photographers, 

and news media approved by the contest director will be 

permitted in the technician team simulated mine rescue 

station. A separate area will be provided for spectators 

to observe the teams during competition. 

13. A predetermined amount of trophies will be awarded for 

the Technician Team Competition. These will include 

separate trophies for the teams using Draeger BG-4 

apparatuses and those teams using Biomarine BioPak 

240R/S apparatuses.

The combined total discounts of the written tests and the 

individual segments of the competition will determine the 

winners. In the event of a tie, the written test scores will 

determine the winner. The total time will be the second 

tie-breaker. The winning teams will be announced during 

the banquet.
66

WRITTEN TEST

each incorrect or unanswered question. Any alterations 

to the test questions or answers will be determined to be 

incorrect by the test judge and discounts assessed.

3. Scoring of the test will be completed by at least two 

qualified judges.

4. In special circumstances, individual team members 

may be given an oral test by one or more judges in 

lieu of a written test. Requests for consideration shall 

be presented to the Contest Director at the time of 

registration. All other team members will take the test at 

the same time. In any case, the judges will not explain 

the meaning of questions, but may explain a word or 

words in the questions.

JUDGES

 1. All judges will be trained as prescribed by the Contest 

Director.

 2. Judges must stand clear of team members.

 3. Prior to the competition, judges will ensure that the 

team’s breathing apparatus(es), multi-gas instrument(s), 

and communications system contain only the deficiencies 

as per the planned problem. 

 4. When unplanned deficiencies are encountered, judges 

will stop the clock, instruct the technician team to turn 

their backs to their respective area, at which time the 

judge will correct the unplanned deficiencies. Judges 

shall instruct the technician team that upon turning back 

to their area, the clock will restart. If the deficiencies are 

caused by either team member, the clock will not be 

stopped.

APPEALS

 1. After the five-minute review, the technician team will be 

notified to report to the area designated for 20-minute 

looks. The team will have 20 minutes for reviewing the 

judges’ scorecards and written test scores. A discount 

summary sheet will be used to list the discounts. All 

discounts will be listed and totaled. Both the technician 
68

team and the review judges will sign the discount sheet 

to certify they have reviewed the discounts and verified 

the totals (see page 95). After the completion of the 

review, the technician team will have an additional 30 

minutes to prepare and submit any appeals. All appeals 

must be in writing and must clearly state the team’s

PROCEDURES FOR GETTING UNDER OXYGEN 

DRAEGER BG-4 BREATHING APPARATUS 

Procedures for getting under oxygen:

 1. Prior to donning the apparatus, make sure a filled 

cylinder, a fresh soda lime pack, and an ice block 

for the breathing air cooler are installed. Don the 

apparatus and adjust the harness and belt.

 2. Don the facepiece by spreading the head harness 

with hands; put chin into chin support and pull 

harness over the head. Tighten the chin straps 

first, then the temple straps, and then the top 

head strap. The facepiece must be sufficiently 

tight on the face to prevent leakage of the 

breathing air which could shorten the duration of 

the apparatus.

 3. Open cylinder valve fully.

 4. Check the digital pressure gauge to see that a 

sufficient oxygen supply remains. The green LED 

light should be displayed. Press the by-pass valve 

to check the by-pass valve operation.

 5. Check the facepiece tightness by tightly closing 

both breathing hoses and inhaling. The facepiece 

should collapse against the face, indicating there 

are no leaks.

 6. Each team member and apparatus should be 

rechecked by the team captain. The team captain 

and apparatus should be rechecked by a team 

member. 

Items to be checked prior to going underground 

and at 20 minute intervals:

 1. Visually check apparatus.

 2. Check pressure gauge.

 3. Question member as to member’s ability to 

continue.

for Horn. When the 240R RMS finishes its battery 

test and horn test and then flashes green, the 

contestant may then turn off the oxygen cylinder 

and bleed the unit by depressing the bypass. This 

takes approximately 50-60 seconds to do this test 

due to the gauge line flow restrictor.

c. A successful test is one in which: 1) Oxygen does 

not leak out of the regulator; 2) Gauge goes to 

flow; 3) Proper RMS light sequence which ends 

up with a green light; and 4) Horn goes on and 

off.

d. Bleed the unit properly by depressing the bypass.

the same mistakes in the same problem. For example; 

improper bandaging on two separate wounds (2 times 

the appropriate discount), three granny knots (3 times 

the appropriate discount), etc.

 4. Teams will not be discounted for doing more than the 

problem calls for, unless it is detrimental to the patient 

or improper care.

 5. If the discount is not listed on the discount sheet and if 

it is not covered under one of the approved rules of the 

contest, judges will not improvise a discount to cover 

the suspected violation.
