A COMPARISON OF "DRY POWDER" AND CHLOROBROMOMETHANE FOR FIRST-AID APPLICATION TO AIRCRAFT CRASH FIRES
Kingman, F.E.T. and Nash, P., 1954. A COMPARISON OF "DRY POWDER" AND CHLOROBROMOMETHANE FOR FIRST-AID APPLICATION TO AIRCRAFT CRASH FIRES. Fire Research Notes99
This report describes tests made to compare "dry powder" and
chlorobromomethane as materials for first-aid applications to aircraft
crash fires. The tests showed chlorobromomethane to be slightly
superior as an extinguishing agent on the size of fire described and
under the weather conditions prevailing. Both materials suffered
from the disadvantage of permitting "flashing back". With the dry
powder was associated a sudden transient increase of the air
temperatures in the aircraft cockpit, while under certain circumstances
the atmosphere produced by the use of chlorobromomethane contained an
undesirably high proportion of toxic products.
