Joseph M. Patterson


Firefighter/EMT Patterson and 2 other firefighters were in the process of draining compressed air from a number of used Self-Contained Underwater Breathing Apparatus (SCUBA) air cylinders in preparation for valve removal and hydrostatic testing.  In some cases, the cylinder valve was inoperable, so a firefighter was partially loosening the pressure-relief burst disc plugs on these cylinder valves.  In the process of draining a cylinder with a loosened plug, the plug separated from the cylinder and the air in the cylinder began to rapidly vent through the opening.  The cylinder became airborne and struck a wall, shearing off the cylinder valve.  The cylinder continued to be airborne, glancing off of an apparatus and striking Firefighter/EMT Patterson in the head.

Firefighters immediately came to the aid of Firefighter/EMT Patterson and he was flown by medical helicopter to a regional hospital.  Firefighter/EMT Patterson was pronounced dead at the hospital.  The cause of death was reported to be blunt force trauma.
