  3. Inspect power-head (engine) for freeness of all moving parts, ensuring that the crankshaft, piston/cylinder and all engine bearings are not damaged.
  4. Check for loose and/or missing parts or mounting hardware; tighten or replace where needed.

  8. Ensure that the recoil starter operates properly and that the rope is not frayed or Ensure proper condition of battery (if equipped).
  9. Ensure all decals (operations and warning) are affixed and legible.

C. Test for Performance

  1. Refer to the owner’s manual for operations and specifications information specific to generator model.
  2. Ensure gasoline is fresh prior to starting the engine. Use a fuel stabilizer in fuel during testing to help ensure proper operation of engine at post storage start up.
  3. Ensure recoil starter functions properly. Check for damage or fraying of pull cord; repair or replace as necessary.
  4. Engine should start easily, run smoothly, be free from fuel leaks, and provide sufficient power to the electrical generator.
  5. Ensure all engine operational controls are functioning properly; stop switch, throttle and choke.
  6. Test for engine performance and electrical output (see owner’s manual for specific performance data).
  7. Should any function fail a test, refer to the manufacturer’s repair manual and troubleshooting guide to correct the problem.
  8. Remove all gasoline from fuel tank and run engine until carburetor is completely empty of fuel.

D. Repackaging

  1. Ensure grounding rod is attached to frame.
  2. Use a nylon “zip-tie” to tie off (seal) starter rope to the frame. 
  3. Attach a certification tag that indicates date last tested (DLT), property #, and name of inspector certifying the performance.
  4. Ensure that all identification (property #, serial #, owner ID) is affixed and legible.

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.
