That was the only luck I had that day it was an old system and was CO2 not powder. No mess only ruined the food cooking and shut down the gas main.
I did see a powder system at a gas station go now that was a mess. We had finished the job and the suppression company came to test the system. One of the sensors was defective when tested it looked ok and they connected the system. Then the about 2 hours later it tripped when some poor guy opened his car hood. When I got there the powder was everywhere including about an inch deep inside his engine compartment!
