Question

technician a says that gasoline vapors are lighter than air, so inspection pits do not have a fire hazard like above ground hoists. technician b says that you should never exceed the lifting capacity of the hoist. who is correct?

○ a. technician a

○ b. technician b

○ c. both technician a and technician b

○ d. neither technician a nor technician b

Explanation:

• Technician A: Gasoline vapors are heavier than air (not lighter), so inspection pits can accumulate them, creating a fire hazard. So A is wrong.
• Technician B: Exceeding a hoist’s lifting capacity is unsafe (can cause failure), so B is correct.

Answer:

b. Technician B
