  2. Inspect hoses for cracks, inspecting for breaks by flexing.
  3. Inspect hose or valve for foreign material that might cause a blocked line.
  4. Inspect O-rings on supply hose and replace if needed.
  5. Inspect for out-of-round fittings by screwing regulator into tank POL fitting.
  6. Return to stock if item passes initial inspection, passes Testing for Performance, is clean, and is serviceable.
  7. Refurbish heater if any damage is repairable, missing or damaged components are available, and it’s economically feasible to refurbish.
  8. Dispose of heaters that have structural damage that prevents repair. Salvage parts that are serviceable for future repairs. Dispose of damaged regulators and cracked or damaged hoses.

Refurbishing Procedures

A. Cleaning

  1. Clean the outside of the heater using a damp cloth. DO NOT clean the heater by spraying water on it.
  2. Clean the inside of the heater using compressed air.

B. Repair

  2. Replace or straighten any damaged or bent parts.
  3. Repair or replace auto shut off valve if not working properly (if applicable.)
  4. Replace any damaged or cracked hose or hose connections.

C. Testing for Performance

  1. Prior to testing use an air hose to blow unit off of any dust, dirt or debris.
  2. Perform initial inspections prior to testing.
  3. Ensure a fire extinguisher is in the work area prior to lighting any heater.
  4. Mount or connect the heater to a LP-Gas supply cylinder.
  5. Turn on gas supply to the heater and check all fittings and connections for gas leaks using mild soap and water solution. NEVER INSPECT FOR LEAKS USING A MATCH OR ANY OTHER TYPE OF FLAME. Should a gas leak occur, shut off the gas supply to the heater immediately and wait a minimum of five minutes before repairing the leak.

RMC Safety Bulletin 26-001: Rhabdomyolysis in Wildland Firefighters

Date:  May 28, 2026
Questions? 
Please contact: Risk Management Committee

The Risk Management Committee (RMC) has issued Safety Bulletin 26-001: Rhabdomyolysis in Wildland Firefighters. Research from 2016 to 2025 shows that 88 cases of rhabdomyolysis (rhabdo) were reported. Analysis of reports from eSafety, the Safety Management Information System (SMIS), and the Wildland Fire Lessons Learned Center (LLC) indicates that rhabdo is common during this time of year due to Work Capacity Tests and contributing factors such as weather, hydration, nutrition, and medication or supplement use.

RMC issued this safety bulletin to raise awareness in the Wildland Fire Community, and to provide research findings and educational resources that support reducing future cases of rhabdo.
