Emergencies & HazardsCâu 101 / 120
A tire on your trailer catches fire at a rest area and you have a 10 B:C extinguisher. What is the realistic limitation you must plan for?
a.The extinguisher will smother the tire fire in a few seconds
b.A burning tire holds heat deep inside and usually needs large amounts of water, so the extinguisher may only slow it while you keep people away and call the fire department
c.Tire fires go out on their own once the vehicle stops
d.Dry chemical is prohibited for use near tires
Giải thích
Tires reignite because the fire burns inside the casing where a dry chemical agent cannot reach, so the priority is evacuation and calling for help. Tire fires do not self-extinguish, and dry chemical is not prohibited, it is simply not sufficient.
