Vacuum Truck Explosion Safety Alert
A vacuum truck operator was in the process of unloading cold heavy crude when he noticed that the 6-inch rubber hose downstream of the blower was smoldering. The truck operator proceeded to discharge his fire extinguisher on the hose and then turned off the blower and closed the truck and tank valves. Shortly thereafter a loud popping sound was heard and then the truck operator was engulfed in flames.
