CA firefighters dealt with fuel containers, ammo, and propane tanks during a fire at Clovis Avenue Self Storage in East Fresno. From firehouse.com :
Firefighters were challenged by the presence of the combustibles as they sought to quell the blaze that eventually spread to 22 separate units, Donis said. Twelve of the units were heavily damaged.
To aggressively fight such a blaze, firefighters typically try to remove all items in a unit to be certain that the fire is eradicated. However, the presence of the highly flammable items, including some detonating ammunition, forced the firefighters to move into a defensive position and pour water on the units from ladders.
