Fuel Geyser Incident Reporting Form

This form is to be used to report fuel geyser incidents from any gas powered equipment, fuel storage or transport container.

Fuel geysering is the rapid and energetic expulsion of vapor/liquid fuel when the fuel tank is exposed to heat and then rapidly depressurized. This similar to a BLEVE - Boiling Liquid Expanding Vapor Explosion.

Information collected in this form will be used by the US Forest Service, National Technology Development Program and industry partners to develop and evaluated engineering solutions.  The information will also assist NWCG to inform power equipment users about effective methods and tools to reduce or eliminate fuel geyser incidents.

All questions in this form are optional, but the more you tell us the better our data is to support geyser mitigation efforts.

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.
