Bio-oil derived hydroprocessed renewable jet HRJ fuel blended with JP-8 is being evaluated for use in United States Air Force USAF aircraft and support equipment and vehicles. The fire protection safety risk to the first responder associated with this fuel must be established. This program was designed to determine if Military Specification MIL-F-24385F Aqueous Film Forming Foam AFFF has the capability of extinguishing large scale HRJJP-8 blended fuel fires. The assessment included quantity of agent required for extinguishment of 465 m2 5,000 ft2 using standard pressure and ultra high pressure delivered from a modified P-19 fire truck. The extinguishment characteristics of HRJ blend fuel fires were compared with fires using pure JP-8 fuel. Heat flux and ambient air temperature adjacent to the fire pit were also measured.
