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.
