The United States Fire Administration has noted with growing concern the number of flash fire incidents linked to lightweight, portable oxygen equipment. The following report describes the general hazards associated with oxygen-enriched atmospheres, including aluminum in contact with high-pressure oxygen, a number of recent incidents, maintenance recommendations, and contributing factors are also included. This report contains information on ten flash fire incidents that involved either fire service or emergency medical service personnel. No attempt was made to analyze experience from the other applications. The incidents resulted in serious injuries to emergency personnel and property damage, including the loss of two ambulances and considerable destruction to a fire station. Patient treatment was affected in some incidents as the newly injured had to be attended to and additional equipment and service providers placed into service.
