Tech A says that gasoline vapors are lighter than air, so inspection pits do not have a fire hazard like above ground hoists. Tech B says that you should never exceed the lifting capacity of the hoist. Who is correct? Tech A
Tech B
Both A and B
Neither A nor B

Tech B is correct.

Explanation:

First, It is international best practice never to exceed the lifting capacity of any hoist. To do so would expose those involved to risks that may prove to be fatal.

Second, research has shown that gasoline vapors, as well as vapor from almost all other flammable or ignitable liquids or substances, are heavier than air.

More specifically, Gasoline produces flammable vapors that are heavier than air by 3 to 4 times. This means they can travel for great distances along the ground. Worst still, inspection pits are must be kept free from gas vapors because they tend to accumulate in low or enclosed spaces.

Both technicians should and must observe all occupational, health, and safety rules and guidelines stipulated and required for their industry/practice.

professionals can use many types of technology that can them. some examples are, computers (they research and can use for programs for data, they are also used for job applications, school work, and even to make new ideas), speedometers (can get data for unknown data), sometimes something as small as a pen (used for rough drafts, to insert data, and again job applications).
