Indoor firing ranges have been built in armories for many years. Each range design reflects the
current emphasis and technology on protecting the health and safety of the shooter. Older ranges may
not meet the current standards deemed necessary to accomplish this. However, under controlled
conditions, many older ranges will not expose users to hazardous conditions.

1-17. Classification of ranges
Based on inspection data collected on the range inspection checklist (Figure 1-2), ranges shall be
classified as “safe”, “limited use” or “unsafe”. Safe ranges permit authorized firing for military and
civilian use. Limited use rariges permit use only under controlled conditions based on the personnel
exposure limits for intermittent Lead exposure. (Figure 1-1). Unsafe ranges are not authorized for use
under any conditions.

a. Building envelope. (Design standards may be found in DG 415-1, Appendix A or CEHND
4110-1-18).

a material that will protect these items and prevent ricochets.

(c) Baffles do not disrupt the uniform airflow in the range.

(d) In older ranges, sidewall windows in front of the firing line have been removed and the
openings sealed flush to the wall with materials compatible with the adjacent walls. New ranges are not
built with windows in front of the firing line.

(2) Unsafe ranges.

(a) All firing lanes are less than 4 feet wide. If any one firing lane is less than 4 feet wide, that lane
shall not be used for firing.

(b) Pipes, conduits or walls are not sealed to prevent migration of Lead dust to other areas of the
range. (See the Addendum for wipe sample procedures used to determine if Lead dust is leaking from
the range).

APPENDIX A
GENERAL PROCEDURES FOR COLLECTING WIPE SAMPLES

A-1 If multiple samples are to be collected at the work site, prepare a rough sketch of the area(s) or
room(s), which are to be wipe sampled.

A-2 A new set of clean, impervious gloves should be used for each sample to avoid contamination of the
media by previous samples and to prevent contact with the substance.

A-3 (1) If using Ghost WipesTM, tear open the individually sealed package. Remove the moistened wipe.
Unfold the wipe.

(2) If using a dry media such as MCE or Whatman" filter, moisten the filter with distilled or deionized
water prior to sampling.

A-4 Place a 10 cm by 10 cm template on the area to be wiped.
A-5 Apply uniform firm pressure while wiping the area inside the template.

A-6 To insure that all portions of the partitioned area are wiped, start at the outside edge and progress
toward the center making progress toward the center making concentric squares decreasing in size.

A-7 After collecting a sample, fold the filter or wipe inward and place into a container and number it. Note
the number at the sample location on the sketch.

A-8 At least one biank filter treated in the same fashion but without wiping, should be submitted to the
laboratory.

APPENDIX B
SAMPLING STRATEGY FOR COLLECTION OF WIPE SAMPLES

B-1 Prior to cleaning the ranges, the three samples must be collected and analyzed for total lead dust on
each surface, i.e., floor, celling, backstop, and wall to include the plenum wall, if applicable. In addition, a
total of 3 samples should be collected from areas which have been least disturbed by airflow.
Established walkways should be avoided.

B-2 Samples should be staggered to different areas of the range. A grid system should be utilized. Each
range surface areas should be divided evenly into 3 by 3 sections. Samples should not be collected on
all one section of a wall or end of the building. .

APPENDIX C
INTERPRETATION OF SAMPLE RESULTS (PRIOR TO CLEANING)

C-1 200 micrograms/sq ft or LESS
If all sample results are 200-micrograms/sq ft or less, the range can be converted and/or used for any

purpose.

C-2 BETWEEN 201 and 200,000 micrograms/sq ft
Range must be decontaminated. Continued with cleaning instructions listed in paragraph 9 Sample
results will be used fo establish a baseline.

C-3 Over 200,000 micrograms/sq ft

Your sample media may not be capable of collecting additional lead dust and results that are above
200,000 micrograms/sq ft, and should be considered suspect.

b. Equipment located near the bullet trap and firing line should be cleaned first and then removed.
The cleaning method depends on the size of the equipment and the material it is comprised of, i.e. metal,
wood, concrete, porus, non-porus, smooth or rough finish etc. However, either HEPA vacuum or the wet
wipe method will be used. Refer to paragraph 9 for additional guidance.

c. Every attempt should be made to clean and reclaim items since disposing of equipment, as
hazardous waste is costly and wasteful. Only as a last resort will the item be discarded as hazardous
waste. Porous items, such as office partitions and carpet that were present during firing should be
considered grossly contaminated and be discarded unless analysis proves otherwise. Consult your State
Environmental Office for the proper hazardous waste disposal methods.

11. Contaminated Sand and Lead Waste
Consult your State Environmental Office for specific disposal guidance to ensure compliance with local
laws and regulations.

42. Medical Surveillance
a. A pre-placement medical examination is required for all individuats involved with range cleanup
operations. Consult 29 CFR 1910.1025 for additional information on medical surveillance requirements.
A medical examination must include—
(1) A detailed work and medical history
(2) A thorough physical examination
(3) A respirator use evaluation
(4) A blood pressure measurement
(5) Blood sample analysis to include:
(a) A baseline blood lead level
(b) A complete blood count (CBC)
(c) Blood urea nitrogen (BUN)
(6) Serum creatinine
(7) Zinc protoporphyrin
(8) A routine urine analysis
(8) Recordkeeping
b. Air Monitoring. Worker breathing zone (BZ) air samples must be collected to ensure personnel are
not overexposed fo airborne lead during the cleanup phase. Representative air samples will be collected
on ail personnel involved in the cleanup operation. These exposure levels will be used to evaluate work
practices and personal protective equipment. Within five (5) working days after receipt of monitoring
results, each employee will be notified in writing of the air sampling results. Contact your Regional
Industrial Hygiene Office for additional information pertaining to air sampling.

13. Worker Education
OSHA 29 CFR 1910.1025 requires that workers who are potentially exposed to any lead level shall be
informed of the content of Appendix A and B of this standard. A training program must be instituted for all
individuals who are subject to exposure to lead at or above the action level or for whom the possibility of
skin or eye irritations exists. The training program shall be repeated for personnel currently invoived in
range cleanup operations, at least annually, this training must be documented on DD Form 1556 or DD
Form 1556-1 and filed permanently in the employee’s Official Personnel File (OPF) or the soldier’s Official
Military Personnel File (OMPF). As a minimum, complete blocks 1, 2, 3, 7, 8, 11, 12, 13, 17, 18, 24, 33
and 36 of DD Form 1556. Place the following statement in block 18, “Do not destroy, retain this record for
the duration of employment/service plus 30 years." The employer will assure that each employee is
informed of the following:
. The content of the standard and its appendices.
. The specific nature of operations that could result in exposure to lead above the action level.
. The purpose, proper selection, fitting, use and limitations of respirators.
|. The purpose and a description of medical surveillance program.
. Eating and drinking are prohibited in lead contaminated areas.

Smoking and smoking materials will not be permitted in contaminated areas.

4-34, Maximum exposure hours

Personnel exposure limits for intermittent atmospheric Lead contamination has been developed by the
U.S. Army Medical Command (MEDCOM) in the form of a table of Lead exposure limits (Figure 1-1).
This table was developed to control intermittent Lead exposure and to establish maximum allowable
hours of exposure based on the airborne Lead concentration and the number of days firing per year.
Intermittent exposures to Lead in indoor firing ranges shall be controlled according to the criteria provided
in the table of Lead exposure limits as an interim control measure only. Maximum effort shall be made to
introduce permanent control measures to reduce the airborne Lead levels to 0.03 mg/m? or less.
Exposure records shall be maintained by the commander of the facility on all personnel who use the firing
range when the airborne Lead levels exceed 0.03 mg/m’, These records shall contain the airborne
Lead concentrations and the amount of time spent on the range for each individual. Other potential Lead
exposure, including off duty firing, may contribute to an individuals overall exposure and should be
considered in establishing maximum allowable exposure time.

1-35. Extent of use

a. The extent of use for any indoor firing range shall be based on permissible exposure of all using
personnel to concentrations of airborne Lead dust.

b. Under no circumstances shall pregnant women be permitted in an indoor firing range, IAW 29 CFR
1910.1025, Appendix C, Section II (5).

c. Personnel under 17 years of age are prohibited from entering any range area with a Lead
concentration greater than 0.100 mgim®. For ranges with Lead concentrations less than 0.100 mgim®,
follow the guidelines in Figure 1-1.

d. Use of the indoor firing range by non-military organizations shall be approved and documented in
writing by the State Safety Manager.

41-36. Medical surveillance

a. Personnel who are or may be exposed to Lead above the action level (0.03 mg/m’) for
more than 30 days per year shall be enrolled in the Medical Surveillance Program.

b. Medical surveillance is not required for intermittent users of indoor firing ranges if the maximum
allowable exposure hours shown in Figure 1-1 is not exceeded.

1-37. Terms

a. Backsplatter-This refers to the small particles, which break off of a bullet as it impacts the bullet
trap. Variables such as the bullet composition, angle of the bullet trap, and the velocity of the impact
dictate the amount and pattern of the backsplatter. A ricochet occurs when the main body of the bullet is
deflected off the surface of the bullet trap.

b. Competent person-An individual who has been specifically trained to identify safety and
occupational health hazards associated with Lead dust and indoor firing ranges. The individual is aware
of current regulations governing indoor firing ranges and of ventilation principles and terminology, air
sampling media and collection requirements and can interpret air sample results. He can provide
appropriate guidance in the abatement of known hazards and has the authority to do so. He can
correctly use diagnostic ventilation evaluation equipment and interpret results. He has received written
authorization from the regional industrial hygiene office to properly evaluate indoor firing ranges.

¢. Plenum-This term refers to a chamber used to build static pressure before the air enters the firing
range. Air is introduced into the plenum from the side, top, or back and is forced through a perforated
wall (calted the plenum wall) behind the firing fine.

d. Smoke Testing-To conduct a smoke test, a smoke candle is ignited behind the firing line. The
smoke is used to check the airflow at and in front of the firing line. There should be laminar flow down the
range to the bullet trap and no turbulence at the firing line. It is also important to ensure the smoke does
not circle back behind the firing line.

a. Reduced-Lead and Lead-free ammunition (non-Lead containing bullets) has become commercially
available. These alternatives to conventional ammunition should be considered for training use if
command policy allows. .

b. Lead-free ammunition is being developed which shall have the same ballistic properties as the
Lead counterparts. The potential exists for some Lead containing ammunition to be completely replaced
by Lead-free ammunition for training and operational uses.

¢. Until Lead-free ammunition is available, Lead exposure can be significantly reduced by the use of
jacketed rounds. Most bullet traps are rated for the use of jacketed ammunition, but this should be
verified with the bullet trap manufacturer.

4-32. Maintenance requirements
a. The following are minimum maintenance requirements, which shail be performed every three
months by the range custodian or by a person designated by the facility commander:
(1) Inspect the ventilation system fan for condition of belts to ensure that the belts are not torn or
frayed and that they are not slipping.
(2) Evaluate static pressure and compare to the baseline static pressure reading. Any changes shall
be reported to the State Safety and Occupational Health Office for further evaluation.
(3) Inspect louvers, if applicable, to ensure they are opening fully.
(4) Lubricate the bullet trap (if applicable).
(5) Inspect the bullet trap for pitting or other damage and for sharp edges on venetian blind type
bullet traps.
b. See the Addendum for a complete list of maintenance requirements for the bullet trap.

1-33. Housekeeping

a. The ventilation system shall be in operation during all cleanup operations.

b. An approved National Institute for Occupational Safety and Health (NIOSH) respirator (P-100) for
Lead exposure shail be used during cleanup operations.

c. During range cleaning operations, workers shall wear coveralls or similar full-body clothing, gloves,
hat and change of shoes or disposable booties, face shields and goggles, or other equipment to protect
the workers skin and eyes.

d. Blowing, shaking or any other means, which disperses Lead into the air, shai/ not be used to
remove Lead dust accumulated on worker's clothing or equipment. A designated area shall be used for
changing clothes to prohibit the spread of contamination. Workers shall shower and change clothes
before release from work.

e. Wet cleaning methods or vacuum cleaning with HEPA filtration shall be utilized during normal
cleaning operations. Dry sweeping, dusting, wiping or blowing with compressed air shall not be
permitted,

f. The range shall be cleaned at the end of each firing day with a HEPA vacuum or wet mop method.

g. When performing the cleaning, clean the floor and all horizontal surfaces fifteen feet in front of and
behind the firing line, or when there is a visible accumulation of lead dust.

h. Wash water contaminated with Lead can be collected and allowed to slowly evaporate leaving
Lead deposits/siudge that may be collected in plastic containers, placed in metal drums, and stored for
future delivery to an authorized hazardous waste disposal site. Drums shail be properly labeled to
identify contents. Disposal of containerized waste shall be coordinated [AW state hazardous waste
program requirements.

i. The State Environmental Office shall coordinate removal and disposal of all containerized
hazardous waste derived from routine use, cleaning, and maintenance of IFRs. Contact your State
Environmental Office for proper disposal instructions when bullet trap catch trays are % full. Spent
cartridge cases shall be collected and processed in accordance with local ammunition inventory and
accountability procedures, AR 710-2, and DA PAM 710-2-1.

j. Prior to converting an indoor firing range to other uses, the entire range area shall be properly
decontaminated of any Lead residue. For cleaning and decontamination instructions, see the Addendum.

(2) Unacceptable Media consists of but is not limited to—
(a) Cotton balls
(b) Baby wipes or wet wipes
b. Documentation of Sample Collection. A Surface Wipe Sample Sheet must be completed and
submitted with samples to your supporting laboratory. A copy of this form is located in Appendix G.
Refer to Appendix A on how to collect wipe samples.

8. Wipe Sampling Protocol
See Appendix A.

9. Ranges Cleaning Instructions

a. Written procedures, such as a scope of work, or Standing Operating Procedure (SOP) that complies
with all federal, state and local regulations must be established prior to decontamination operations, The
range ventilation system will be in operation during range cleaning to ensure that a negative pressure
environment is maintained. In the absence of mechanical ventilation system, all doors and windows will
be sealed to eliminate fugitive emissions. A High Efficiency Particulate Air (HEPA) filtered vacuum
system is the preferred method of cleanup followed by wet wiping of the range. The HEPA vacuum is
designed to collect loose surface lead dust particles.

b. Any general purpose cleaning solution can be used. However, Spic and SpanTM has been found to
be an effective cleaning solution by other Army organizations. Mix new solutions of cleaning solution
frequency. Wet wiping will require dual containers of water; one container for wetting the applicator
(mops, rags, sponge, etc.) and the other container for rinsing the applicator after the dust has been wiped
from the surfaces. When placed in containers, wastewater should be left fo evaporate.

c. PROPERLY DISPOSE OF ALL HAZARDOUS WASTE, DO NOT PLACE LEAD CONTAMINATED
WASTE INTO THE SEWER SYSTEM OR ONTO THE GROUND.

d. Mop-heads, sponges and rags will be discarded as hazardous waste following cleanup.

e. Wet cleaning by a high-pressure system is prohibited, as this method may embed the lead into the
substratum and generate large quantities of unwanted hazardous waste.

f. Dry sweeping is not permitted.

g. All surface areas of the range must be cleaned. Do not remove the coating on smooth painted
surfaces that are properly sealed.

h. Wood floors should receive a coat of deck enamel or urethane; concrete floors should be sealed
with deck enamel and linoleum or tile floors should be waxed.

i. A progression of cleaning from top to bottom and from behind the steel backstop to the firing line
should be used. After removing the sand, if applicable, and the steel backstop, areas in front of and
behind the bullet trap along with the stee! backstop plate(s) should be cleaned. Next, clean the ceiling,
lights, baffles, retrieval system, heating system(s), and ventilation duct(s). Acoustical material should be
vacuumed and removed rather than painted over.

j. A Toxic Characteristic Leaching Procedures (TCLP) test for lead only may need to be performed on
the acoustical material. A TCLP test will determine if the material is classified as “hazardous” and can be
disposed of in a sanitary landfill. Contact your State Environmental Office for assistance before arranging
for this laboratory testing. The floor should be the last surface cleaned, starting at the bullet trap and
ending behind the firing line.

k. After wet wiping all surfaces, permit the area to dry. Vacuum all surface areas until no dust or
residue can be seen using the HEPA.

|. A thorough visual inspection to detect dust should be made following cleanup and prior to collecting

3. Explanation of Abbreviations and Terms
Abbreviations and special terms used in this publication are listed in the glossary.

4. Policy and Procedures
Conversion of Ranges. Indoor firing ranges can be safely rehabilitated or converted for other uses, such
as a storage area, kitchen, or office space, provided the following —

a. Previously active ranges must be thoroughly decontaminated and cleaned to acceptable levels.

b. The level of cleanliness is to be determined by sampling. The Occupational Safety and Health
Administration's (OSHA) Technical Manual, & Edition, provides guidance on the methods and techniques
needed to collect wipe samples (Appendix A).

(1) Wipe samples must be collected and analyzed prior to and after cleaning.

(2) Post-cleaning surface wipe sample results must be less than or equal to 200 micrograms per
square feet (ug/sq ft). The sampling strategy, which is the amount and location of wipe samples to be
collected, is provided in Appendix B. Methods for interpreting the sample results are contained in
Appendix C and D.

c. Equipment/ltems previously stored in the range must be decontaminated and cleaned to acceptable
levels.

(1} Samples must be collected from equipment/items stored in the range. Sample selection is critical,
because the number of items stored and length of storage differs from range to range. The amount and
location of the samples, should be representative of the areas where lead dust is most likely to
accumulate. The more samples collected, the better the statistical comparison of the results.

(2) Samples must be collected from the smooth surfaces of the equipment/items, in so much as
possible. Results of samples collected from a rough surface will be inaccurate due to the minimal surface
contact of the media. Further, the likelihood of tearing the media filter is greater on rough surfaces.

(3) Samples should also be collected on items stored the longest period of time, and which have not
been disturbed. Items stored closest to the bullet trap and firing line are likely to have higher
concentrations of lead dust. Methods for interpreting the sample results are contained in Appendix C and
D.

5. Goal

To ensure every indoor firing range is free of lead dust, and to reduce the number of unsafe ARNG indoor
firing ranges. ,
6. Background

The Environmental Protection Agency (EPA) identifies lead as a highly toxic metal. Elemental lead is
indestructible, and common in the environment. Lead can enter the body by inhalation (breathing) or
ingestion (eating). In addition, lead is a cumulative poison. it accumulates in the blood, bones, and
organs, including the kidneys, brain and liver. Effects include nervous and reproductive system disorders,
delays in neurological and physical development, cognitive and behavioral changes, and hypertension.
Symptoms include loss of appetite, difficulty sleeping, irritability, fatigue, headache, and inability to
concentrate. It can stay in the bones for decades. Worker awareness and training are important to
ensure that employees can recognize the symptoms of exposure and get prompt medical attention.

7. Wipe Sample Media
a. OSHA Technical Manual provides the necessary guidance on the technique needed to collect wipe
samples (Appendix A). Only distilled or deionized water will be used to saturate dry sample media. At
least one field blank filter must be submitted with each sample sheet. The field blank must be from the
same lot, and labeled as a blank on the sample sheet. Appendix E identifies how and where to obtain
sample media. Use the following guidance for determining media acceptability.
(1) Acceptable Media consists of -

(a) Ghost WipesTM (PREFERRED METHOD)- Pre moistened

(b) Thirty-seven (37) millimeters (mm) mixed cellulose ester (MCE) filters, with or without the
cassettes.

(c) Eleven (11) centimeter (cm) diameter Whatman TM #40 paper.

14. Personal Protective Equipment

For housekeeping and rehabilitation the employer shall select respirators from among those approved for
protection against lead dust, fume, and mist by the National Institute for Occupational Safety and Health
(NIOSH). The employer shall institute a respiratory protection program in accordance with 29 CFR
1910.134. As a minimum, personnel conducting the decontamination of the range will be provided with
the following personal protective equipment.

a. Employees engaged in range rehabilitation and/or range conversion, the employer shall provide at
no cost to the employee, and assure that the employee uses appropriate protective work clothing and
equipment such as, but not limited to:

(1) Protective coveralls with hood and shoe covers or disposable Tyvek TM full body suit.
(2) Disposable rubber gloves; and disposable shoe coverlets (If necessary).
(3) Full-face air purifying respirator with P-100 cartridges.

b. The employer shall provide the clothing required in a clean and dry condition at least daily to
employees engaged in the conversion of indoor firing ranges.

c. The employer shall provide for the cleaning, laundering, or disposal of used or contaminated
protective clothing and equipment.

d. The employer shall assure that all protective clothing is removed at the completion of a work shift
only in areas designated for that purpose (Change Areas or Change Rooms).

e. The employer will ensure that contaminated protective clothing that is to be cleaned, laundered, or
disposed of, is placed in a closed container in the change area that seals sufficiently enough to prevent
dispersion of lead dust.

f. The employer will further inform in writing any person who cleans or launders protective clothing or
equipment of the potentially harmful effects of exposure to lead.

15. Housekeeping

This chapter applies to all active indoor ranges classified as "safe" for use. To keep the range operating
properly and to keep possible hazards to a minimum, a routine housekeeping/ maintenance program is
essential.

a. The employer must establish a housekeeping program sufficient to maintain all surfaces as free as
practicable of accumulations of lead dust. To this end the range will be clean at the conclusion of each
firing day.

b. The range ventilation system will be in operation during ail cleaning operations, to ensure a
negative pressure environment Is maintained.

c. Ranges will be cleaned by using the wet method or vacuuming. A HEPA (High Efficiency
Particulate Air) filtered vacuum system is the preferred method of meeting this requirement. The use of
compressed air to clean floors is absolutely prohibited. If the wet method is utilized the floor should be
equipped with a floor drain, and collection system. When there is no collection system, the water can be
allowed to slowly evaporate leaving lead deposits/sludge. The deposits/siudge can then be collected,
placed in metal drums, and stored for future delivery to an authorized hazardous waste disposal site.
Drums must be labeled to identify contents, in accordance with the hazardous waste program.

d. ANIOSH approved respirator (P-100) for protection against lead dust, fume, and mist will be worn
at all times while cleaning.

e. When cleaning start behind the firing line forward, cleaning the floor and horizontal surfaces.
