Emergencies & HazardsCâu 90 / 120
You are using a fire extinguisher on a small cargo fire. What is the correct technique?
a.Stand as close as possible and aim at the top of the flames
b.Empty the extinguisher into the smoke above the fire
c.Stay upwind, position yourself about 6 to 10 feet away, pull the pin, aim at the base of the fire, and sweep side to side
d.Approach from downwind so the wind carries the agent in
Giải thích
Aiming at the base attacks the fuel source, and staying upwind and back keeps you clear of heat and fumes. Standing too close, spraying smoke, or approaching from downwind exposes you to the fire and wastes the extinguisher's limited charge.
