Propane Tank Hazards

 

Liquefied Propane Gas (LPG) tanks are commonly found in the wildland urban interface and present hazards to firefighters in that environment. LPG tanks may be found around motor homes, travel trailers, grills, camp stoves, lanterns, etc. Directly attacking LPG tank fires is a structural fire task involving hazardous materials and should only be attempted by trained personnel using full structural personal protective equipment and equipped with a volume of water adequate to safely attack the fire.

Boiling Liquid Expanding Vapor Explosions (BLEVE)

  • The most recognized hazard with LPG tanks is BLEVE or sudden complete failure of the tank. Some training courses have directed responders to approach the tank from the sides, believing that the force of the explosion will occur on the ends of the tank. However, this is not a guarantee that you will be safe from projectiles or missiles from the explosion as they may travel in all directions up to 2,500 feet away. Leave the area immediately if you smell propane, hear a rising sound from venting safety devices, or see discoloration or deformation of the tank. Move at least 2,500 feet away, and do not go downwind or downslope of the leaking propane. BLEVEs are a major hazard to emergency responders!

Fuel Reduction Around Tanks

  • Wildland firefighters may take action to prevent direct flame impingement on LPG tanks by removing wildland fuels in the area. However, be aware that lines from the tank to structures may be above or below ground and may be cut by tools or equipment. Propane gas is heavier than air. It may move along the ground at some distance and may ignite when in reaches open flame or another ignition source. Use extreme caution when doing fuels reduction around tanks, and flag any lines you encounter.

Other Wildland Fire Considerations

  • Do not position engines or other apparatus near LPG tanks or downwind/downslope from tanks.
  • Do not deploy fire shelters near LPG tanks or downwind or downslope from tanks.

Cooling Tanks

  • In light fuels such as grasses, where any heat exposure to the tank will be very limited, the rapid application of cooling water on the outside of the tank above the liquid level can reduce the likelihood of container failure by lowering the external temperature of the shell of the exposed tank. Water should not be directed at the valve safety devices, due to the potential of icing the valve closed.
  • In heavy fuels where long duration heat exposure to the LPG tank is likely, evacuate all personnel and equipment to 2,500 feet away and not downwind or downslope. The National Fire Protection Association (NFPA) says that direct flame impingement protection requires water flow of at least 500 gallons per minute from an unmanned monitor nozzle. This is a situation for properly trained, equipped, and supported structural firefighters.

Please contact: Leadership Committee

NWCG is excited to announce that the Quarter Two materials for the 2025/2026 Wildland Fire Leadership Campaign are now available! This annual initiative invites all leadership and wildland fire management students to engage with essential skills and knowledge needed to lead effectively in dynamic environments.

This quarter focuses on Leadership Level 2: New Leader (Conveying Intent). Conveying intent is a crucial leadership competency in the high-risk, dynamic environment of wildland firefighting. Months 4 - 6 will concentrate on how successfully conveying intent enhances situational awareness, promotes shared understanding, and empowers firefighters to exercise initiative and adapt to changing conditions.

NWCG is currently recruiting SMEs for the following positions:

  • Aircraft Timekeeper (ATIM)
  • Compensation/Claims Unit Leader (COMP)
  • Cost Unit Leader (COST)
  • Crew Representative (CREP)
  • Deck Coordinator (DECK)
  • Fire Effects Monitor (FEMO)
  • Field Observer (FOBS)
  • Geographic Information System Specialist (GISS)
  • Ordering Manager (ORDM)
  • Receiving/Distribution Manager (RCDM)
  • Staging Area Manager (STAM)

Projects begin April/May 2026 and require 15–20 hours per month for 6–8 months, including a five-day workshop in Boise, Idaho this May. Apply by February 27, 2026, at the link below and review the attached document for details.
