Water causes a violent flare-up when applied to a fat fire because the liquid expands rapidly into steam.0:14 Fiberglass hulls burn uncontrollably once a fire takes hold, making abandonment to a life raft the only safe option if initial firefighting efforts fail.0:47 Life rafts lack fire resistance, so crews must evacuate before heat radiation becomes extreme.0:50 Proper extinguisher use requires aiming at the base of the fire and sweeping side to side.1:34 Foam extinguishers starve Class A and B fires of oxygen, while carbon dioxide extinguishers require close proximity to prevent wind from dispersing the gas.2:07 Users must avoid touching the CO2 nozzle, which freezes during discharge.2:14 A 2013 incident involving a yellow duck tour boat near Westminster illustrates the necessity of rapid evacuation, where 30 people jumped into the water after their vessel caught fire and was subsequently rescued by the London Fire Brigade and three RIBs.2:40
