Initial Inspection/Disposal Criteria

  1. Visually inspect for evidence of use i.e., dust, oil, damage, loose or missing parts.
  2. Return to stock if there is no sign of use or damage and priming bulb can be squeezed easily.
  3. Refurbish as necessary if the assembly has been used, damaged or is incomplete.
  4. Dispose of the Fuel Line Assembly if it is not economically repairable.

Refurbishment procedures

A. Cleaning

  1. Remove dirt and oil using detergent and shop towels as necessary.
  2. Use pressure washer and degreaser to remove heavy deposits of oil and grease.

B. Repair

  1. Replace fuel hose if there are cuts, tears, burns or other defects.
  2. Tighten the quick disconnect fitting if loose.
  3. Replace cracked, torn or missing O-rings on quick disconnect fitting.
  4. Replace any ¼” fuel hose that is not gasoline, oil and ozone resistant. *Remove Goodyear INSTA-GRIP hose from service during the refurbishment process.
  5. Replace priming bulbs that are too stiff and cannot be squeezed easily.
  6. Replace fuel hose sections if assembly is not a minimum of 54” overall length.
  7. Replace worn brass swivel fittings that have been rounded over by wrenches.
  8. If assembly has an in-line fuel filter, replace the filter at each service.
  9. Secure hose connections using pinch type Ear Clamps (Oetiker® clamps).

C. Test for Performance

  1. Check function of priming bulb by squeezing; air should escape at hose-end opposite of quick disconnect fitting.
  2. Pressurize fuel line assembly to 8-10 psi and seal off, ensuring that there is no leak-down in pressure. If pressure will not hold, submerge in water or spray hose with soapy water to indicate source of air leak, repair as necessary and retest.

D. Repackaging

  • Local cache option.

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.
