A. Cleaning Requirements – General Requirements

● All personnel shall be trained and certified in accordance with regulatory lead hazards and shall also be trained and certified in accordance with applicable local environmental cleanup requirements.

● The IFR ventilation system shall be on during all maintenance and cleanings.

● Place walk-off sticky mats just outside of all access/exit doors to the IFR.

● Collect spent brass shells in 2 to 5 gallon sealable bucket(s) labeled “brass only”. Collect spent lead in in 2 to 5 gallon sealable bucket(s) labeled “lead only”. Store buckets in a secure area (i.e. bullet trap room if available) until the disposal/recycling pickup.

● Inspect, clean and maintain firearm accidental discharge clearing trap per manufacturer’s recommendations.

● Cleaning of the range areas will be done in a sequential manner to minimize the spread of dust (i.e. from clean to less clean - start cleaning from the control room side moving towards the backstop and backstop access area.

● Wet wipe with a lead specific cleaner all surfaces in the firing range, control room, gun cleaning area, storage room, secured storage room, and backstop service room (if present) including; but not limited to walls, baffles, ceilings, firing lane partitions, target rails, backstop, bullet trap, doors and knobs, light switches, countertops, shelves, exhaust filter frames/housings, ducting, etc.

● Floors and surfaces that are not smooth and, consequently, cannot be wet wiped shall be HEPA vacuumed. This will include all noise reduction insulation (i.e. walls and ceiling).

HEPA vacuum all areas within 15 feet outside of bullet trap access door and any range exit doors.

● Verify that all alarms and fan interlocks are working properly and document any issues on the Table 4 - Inspection Checklist .

● Inspect signage, lighting, targeting systems, storage areas, and cleaning facilities associated with the IFR. Repair if possible, any signage, lighting, storage areas, and cleaning facilities.

Clearly document any identified damage or items needing repair on the Table 4 - Inspection Checklist notes section.

● Dura Block Type backstop o Inspect the Dura Blocks for excessive damage, o Replace heavily damaged Dura blocks, and o Move lightly to moderately damaged Dura blocks to perimeters of backstop.

● HVAC System and Filters o Determine the pressure drop for each filter level including pre-filter and HEPA filter.

o If there are no pressure sensors installed to measure pressure differential before/after filter levels, sensors must be installed or portable monitors used.

� The installed pressure sensors shall feed to the DDC of the IFR (if applicable).

� If only one (1) pressure differential sensor is installed to measure the pressure drop of both the pre-filters and final filters and the pressure drop is significant, February 7, 2022 replace the pre-filters and check full pressure drop of both filter sections combined.

o Measure full volumetric exhausted airflow (cfm).

� Calculate airflow (cfm) for each HEPA filter. Use this number to compare to filter manufacturer’s pressure drop vs. airflow volume to determine change out requirements.

o Replace HVAC filters (pre-filters and/or HEPA) only if there indicates a pressure drop more than twice the manufacturer’s pressure drop for the designed air flow (i.e. 1” wg @ 2400 cfm for HEPA filters).

o Filters requiring replacement per above will be replaced by GSA-furnished filters that meet the specifications of USMS Publication 64, Section A10.2. The filters shall consist of a pre-filter stage of a minimum MERV 8 rating followed by a final filtration stage.

Final HEPA filter(s) shall have a minimum MERV 17 rating (99.97% capture efficiency at 0.3µ IEST type A).

o Wet wipe the inside of the exhaust filter housing if potential exists for contamination .1

February 7, 2022

● The sampler shall locate the smoke generator at the locations where the guns will be discharged (i.e. hold smoke generator with arms outstretched in front of shooter for approximately 10 seconds) for each of the locations and positions listed in #1 above. Allow for normalization of position (about 10 seconds) before recording smoke movement in sketch.

● Please provide a sketch of the smoke movement from each lane and the 3 positions.

o Ideal sketch will use three colors, one color each for the shooters/samplers positions.

o Green color indicating standing position, blue indicating kneeling position, and red indicating prone position.

o Smoke movement lines should be sketched onto the diagrams provided.

o These sketched lines should start on the diagrams from the shooting location (estimate) and be drawn through to the perspective where the smoke disappears or becomes too diluted to observe. The length of the sketched lines should proportionally estimate the actual length and direction(s) the smoke traveled onto the provided diagram (i.e. a 4’ actual is equal to about 1/2” on diagram).

● Record airflow velocities (fpm) in the breathing zone of the shooter (or sampler) for each of the lanes/positions indicated in #1 above. Breathing zone is identified as within approximately 1 foot of the nose/mouth, preferably to the side in this case.

● Downrange airflow velocities (fpm) (mid-range and in front of backstop) should be taken in the middle of each lane, approximately midway from the floor to the bottom of the ceiling baffles.

● Supply air volumetric measurements (cfm) should be taken at the outside air supply vent using applicable procedures for accurate measurements.

● Exhaust air volumetric measurements (cfm) should be taken at the final outside air exhaust vent using applicable procedures for accurate measurements.

o If this is not a single pass HVAC system (i.e. with return air ducting, shared ventilation with other areas, etc.) please note on Table 4 - Inspection Checklist notes section.

Notes:

*Measurements of total volumetric airflows may be done using the measured ESP at both the supply fan and exhaust fan locations. Volumetric airflow can then be calculated using the fan manufacturer’s airflow / fan speed curves.

ACTIVITY

• Check unit and record any unusual bearing noise, vibration, odor, corrosion, and structural damage.

• Throw unit power disconnect switch to off position. Use appropriate Lock Out/Tag Out

(LOTO) procedures and lockout tools to assure power isn’t initiated accidentally.

• Install new filters if pd for filter stage is greater than 2x manufacturers recommendations for the specified airflow. Record filter information. Replacement with filters in accordance to USMS Pub 64.

• Remove old filters and place into white plastic garbage bags.

• Mark garbage bags as lead containing waste and follow USMS Pub 64 for disposal/recycle.

• Check that filter doors and access panels are secure with no air leakage. Repair seals as needed.

• Throw unit power disconnect switch back to the on position. Use appropriate LOTO procedures and appropriately remove lockout tools and tags.

• Clean up and secure work area.
