Emergencies第 68 / 80 题
When should you use your fire extinguisher on a hazmat fire?
a.Always, no matter the size
b.Never under any condition
c.Only after the fire spreads to the cargo
d.Only on small fires you can safely control, such as a tire or engine fire before it reaches the cargo
解析
A driver's extinguisher is meant for small fires, like a tire or engine fire, caught early before they reach the hazardous cargo. Once flammable or reactive cargo is involved, the fire is too dangerous to fight without proper equipment. In that case, keep back and wait for trained responders.
