## E. 	When smoke is encountered, it will be considered to extend to a placard stating the “end of smoke” or a separation intended or indicated to be airtight.
 If carbon monoxide, methane, or oxygen deficiency is found in an opening containing a separation intended or indicated to be airtight, the gas will be considered to extend to the airtight separation or to a placard indicating a change in the gas constituents.  If carbon monoxide, methane or oxygen deficiency is encountered in other locations, it will be considered to extend to the next normal area to be tested for that gas, depending on direction of team travel, at which time the continuance or discontinuance of the gas will be determined by placards or by results of the tests.  See Figure 4.

- Removing water roofed
- When retreating out of a barricade or coming back through a stopping where an airlock has been erected, it will not be necessary to airlock on the way out if this will not change any existing ventilation.

## Person behind the barricade, stopping, etc.
No airlock for “airtight”
An airlock is formed by erecting a temporary stopping at a location(s) that will provide the equivalent airtight separation as the airtight structure or condition breached by the team.  An equivalent airtight separation would require an airlock built for each airtight structure removed within one crosscut. An equivalent airtight separation must also be maintained when pumping water roofed.

- No airlock for “airtight”
- An airlock is formed by erecting a temporary stopping at a location(s) that will provide the equivalent airtight separation as the airtight structure or condition breached by the team.  An equivalent airtight separation would require an airlock built for each airtight structure removed within one crosscut. An equivalent airtight separation must also be maintained when pumping water roofed.

- If the water roofed is in an entry or crosscut one build is required; a 3-way intersection two builds are required; a 4-way intersection three builds are required.  If there are two sides blocked, one airlock is needed.  If there are three sides blocked, two airlocks are needed.  If four sides are blocked, three airlocks are needed.  This is the minimum requirements for a solid line map and may not prevent air movement on a dotted line map.

## 43. Failure to erect temporary stopping, reasonably airtight, each infraction___2

## 44. Failure of team to explore or examine workings systematically and thoroughly, each omission___4
Inaccessible: All areas of the mine where team travel is blocked by one or more of the following conditions:
Seals
Unsafe roof rib to rib
Inextinguishable fires
Water over knee deep 
Caved areas

- Inaccessible: All areas of the mine where team travel is blocked by one or more of the following conditions:
- Seals
- Unsafe roof rib to rib
- Inextinguishable fires
- Water over knee deep
- Caved areas

- Opening: Any entry or mining that was performed off an entry, room, or crosscut that may or may not connect to another entry, room, or crosscut.
- Crosscut: An opening that connects two entries.
- Contaminant:	Any one or more of the following:
- Smoke
- Carbon monoxide above 10 PPM
- Methane above one percent
- Less than 19.5 percent oxygen

## Unless blocked, teams must advance in the contaminated entry or in entries adjacent to the contaminated entry.  When a contaminated entry and adjacent entries are blocked, teams may explore/advance in other nearest accessible entries.  However, the team will be discounted if it fails to return to the contaminated or adjacent entry at the first open crosscut, and if not blocked, make all further explorations in the contaminated or adjacent entries before advancing into other areas of the mine.

If the team encounters contaminants in multiple entries, the team has the option of which entry to examine first. As the team advances into a contaminated entry and subsequently encounters a placard indicating that all contaminants are cleared prior to reaching an intersection, the team must stop (prior to the captain passing the placard(s)) and make further advances in the other contaminated or adjacent entry.

- If the team encounters contaminants in multiple entries, the team has the option of which entry to examine first. As the team advances into a contaminated entry and subsequently encounters a placard indicating that all contaminants are cleared prior to reaching an intersection, the team must stop (prior to the captain passing the placard(s)) and make further advances in the other contaminated or adjacent entry.

## When advancing in an entry and an intersection is encountered with open crosscuts on both sides, the team would be required to tie across into the contaminated crosscut first unless the team is required to return to a contaminated entry.

**If the team encounters a contaminant in both crosscuts, the team has the option of which crosscut to examine first.  As the team advances into a contaminated crosscut and subsequently encounters ****a placard indicating that all contaminants are clear**** prior to reaching an intersection, the team must stop (prior to captain passing the placard****(s)****) and make further advances in the other contaminated crosscut.**

## Passing or failing to explore an open crosscut.
Team would be required to travel into this opening and tie across into the next intersection.  Teams cannot advance from this intersection before tying outby unless the outby entry is blocked.  Teams advancing inby an opening to a point that the No. 5 team member is at or inby the inby rib line will be considered to have passed that opening. If a contaminant is found in an open crosscut, teams would be required to tie across in this crosscut after accessible outby areas have been explored. 

- Team would be required to travel into this opening and tie across into the next intersection.  Teams cannot advance from this intersection before tying outby unless the outby entry is blocked.  Teams advancing inby an opening to a point that the No. 5 team member is at or inby the inby rib line will be considered to have passed that opening. If a contaminant is found in an open crosscut, teams would be required to tie across in this crosscut after accessible outby areas have been explored.

## Where crosscuts are blocked, the No. 5 team member may not advance beyond the inby corner of the second crosscut before the team ties across and/or behind into all accessible areas outby that crosscut. After the accessible areas outby are completely explored to the side where the two crosscuts were determined, the team will be permitted to explore the original entry until it encounters the second crosscut to the other side. This may require building an airlock or ventilation controls such as a stopping, door, etc., or returning to the fresh-air base, and exploring into other entries at the discretion of the team and according to the conditions of the mine.
This rule requires team to make all accessible areas outby the second crosscut limit (this would include all sides of areas that are inaccessible such as caved, etc.).

- This rule requires team to make all accessible areas outby the second crosscut limit (this would include all sides of areas that are inaccessible such as caved, etc.).

## Inaccessible areas need not be explored unless the team has explored all accessible areas and there are unaccounted for persons or an explosive mixture to be moved through the inaccessible (unexplored) areas.
Teams will be required to pump water or support the roof to explore the inaccessible areas in these cases, if the necessary materials are provided in the problem.
Exploration behind seals is not necessary unless required by the problem

- Teams will be required to pump water or support the roof to explore the inaccessible areas in these cases, if the necessary materials are provided in the problem.
- Exploration behind seals is not necessary unless required by the problem

## 45. Only the ventilation material provided will be permitted to be used during the working of the problem.  Erected walls of overcasts/undercasts cannot be removed or altered by the team.  An overcast cannot be rebuilt as an overcast if completely destroyed, but if the materials from the destroyed overcast are on the field they can be used to build temporary stoppings.  Other structures located on the course shall be completely disassembled when moved to other locations.___10

(Exception: Brattice frames and brattice cloth may be used to erect a line curtain which can only extend from a face or barricade to the outby intersection.)
Team members holding up brattice cloth in an attempt to clear a contaminant shall be discounted under this rule and the contaminant shall not be cleared.
