Initial Inspection/Disposal Criteria

  1. Inspect for burrs and cracks, broken plastic, or fire damage. Inspect gasket and replace if missing, cracked, or stiff.  Inspect for screw and nylon washer.  Inspect hose coupling threads for damage.
  2. Barrel must turn freely.
  3. Return to stock if nozzle functions properly, is free of damage and clean.
  4. Refurbish if nozzle is repairable.
  5. Dispose of any nozzle that is damaged beyond repair, has burn damage, or fails Testing for Performance and deficiencies cannot be corrected. Old style KK: Inspect threads inside of barrel; if they are damaged, dispose of nozzle.

Refurbishing Procedures

A. Testing for Performance

  1. Replace gasket if necessary.
  2. Connect nozzles to pump or manifold. Confirm connection ends are not out of round and there is no damage to threads.
    1. Pressure Test:
      1. Start pump.
      2. Make sure nozzles are open. Let all air escape. Shut nozzles.
      3. Pressurize to 300 PSI and hold for 3 minutes
  3. Inspect for leak:
    • Around the gasket
    • Behind the barrel
    • The tip of the barrel
      ​Note: Due to manufacturing processes a water tight shut-off seal on NFES #000137 and #000138 is very difficult to attain. Minimal drips or slight mist spray from the tip are acceptable for RFI condition.

B. Cleaning

  1. All items will be washed and cleaned of foreign matter, such as mud, dirt, and grease. Clean in a mild detergent with brush and scouring pad, or high pressure wash as needed. Do not soak for extended periods of time as the detergent will corrode the metal.
  2. Rinse thoroughly.
  3. Stand upright with barrel in open position to drain water and dry.
  4. Lubricate threads on back of the barrel with appropriate dry lubricant (graphite).

C. Repair

  1. Replace gaskets, washers or screws as needed.
  2. If plastic nozzle is found defective, dispose (NFES #000137, #000138).

D. Retesting

  • Following completion of any repairs, retesting of nozzles must be completed following Testing for Performance, above.

E. Repackaging

  • Stand upright and dry completely prior to repackaging.
    • Use NFES #008064 carton (10” x 8” x 6”)
    • Use NFES #008018 carton (12” x 12” x 6”) 10 PER CARTON 
    • Use NFES #008017 carton (18” x 12” x 10”) 60 PER CARTON

ETC/RMC Safety Bulletin: 25-001 New Guidance on Laundering Wildland Fire Clothing to Reduce Contamination

Date: Aug 8, 2025
Questions? Please contact:
Equipment Technology Committee
 Risk Management Committee

The Equipment Technology Committee (ETC) and the Risk Management Committee (RMC) have issued Safety Bulletin 25-001: Laundering to Decontaminate Wildland Fire Clothing. Recent research revealed that wildland fire flame-resistant pants and shirts can be contaminated with chemicals from combustion byproducts, including carcinogens, and that common laundering practices can effectively remove these harmful contaminants from wildland firefighter clothing more effectively than previously understood. It is recommended to decontaminate wildland fire clothing as frequently as possible. 

Frequently Asked Questions about this new information and how to implement recommendations can be found on the NWCG Alerts page. Read the complete ETC/RMC Safety Bulletin: 25-001 to learn more.
