Question 1

Rubber gloves are always the best choice for any type of job.

Accepted Answer

Rubber gloves are suitable for certain tasks, especially those involving chemicals or cleaning, but not all jobs. Different tasks may require different types of gloves for optimal protection and performance.

Question 2

Water can be used to extinguish any type of fire.

Accepted Answer

Water is not suitable for extinguishing fires involving flammable liquids, electrical equipment, or reactive metals, as it can spread the fire or cause dangerous reactions.

Question 3

GFCI outlet is designed to prevent excessive current from flowing through an electric circuit.

Accepted Answer

A GFCI (Ground Fault Circuit Interrupter) outlet is designed to protect against electrical shock by detecting ground faults and interrupting the circuit, not by preventing excessive current flow.

Question 4

Lead-acid batteries cannot explode since they only contain lead and water.

Accepted Answer

Lead-acid batteries can explode due to the production of hydrogen gas during charging, which can ignite if exposed to a spark or flame.

Question 5

Chemicals are only dangerous if you breathe in vapors, accidentally swallow some of the chemical, or get the chemical in your eyes.

Accepted Answer

Chemicals can also be dangerous through skin contact, prolonged exposure, or if they react with other substances to produce harmful byproducts.

Question 6

The best way to prevent an eye injury is to__________.

Accepted Answer

Wearing approved safety glasses is the most effective way to protect your eyes from potential injuries when working with metal or other hazardous materials.

Question 7

Technician A says that an MSDS would be consulted to determine the specific type of personal protective equipment that should be worn when working with a chemical. Technician B says that non-flammable chemicals cannot hurt you. Who is correct?

Accepted Answer

Technician A is correct because an MSDS (Material Safety Data Sheet) provides information on the safe handling and use of chemicals, including the appropriate personal protective equipment. Technician B is incorrect because non-flammable chemicals can still be harmful in other ways, such as being toxic or corrosive.

Question 8

Who is ultimately responsible for personal safety?

Accepted Answer

Each technician is ultimately responsible for their own personal safety, as they must follow safety protocols and use protective equipment correctly.

Question 9

Technician A says that the third prong on a North American 120V AC electric cord always indicates a three-phase voltage. Technician B says that the third prong on a 120V AC electric cord can be broken off if an extension cord is used. Who is correct?

Accepted Answer

The third prong on a North American 120V AC electric cord is a ground prong, not an indicator of three-phase voltage. It is a safety feature and should not be broken off.

Question 10

While working with diesel fuel, a fellow technician approaches you and lights up a cigarette. What should you do?

Accepted Answer

Smoking near diesel fuel is a safety hazard due to the risk of fire or explosion. It is important to ask the technician to go to an approved smoking area to ensure safety.

Question 11

Accepted Answer

Hearing protection should be worn in all the situations listed as they all involve exposure to potentially harmful noise levels.

Question 12

Which of the following should NOT be worn in a truck repair facility?

Accepted Answer

Baggy or loose clothing, jewelry, and sandals can pose safety hazards in a truck repair facility, so none of them should be worn.

Question 13

A hybrid-electric truck is being serviced. Technician A says that orange-colored wire insulation indicates 12V circuits. Technician B says that although he has no experience working with hybrid electric trucks, the only way to learn is by doing. Who is correct?

Accepted Answer

Orange-colored wire insulation in hybrid-electric vehicles typically indicates high-voltage circuits, not 12V circuits. Technician B's approach is unsafe as working on high-voltage systems without proper training can be dangerous.

Question 14

Which of the following is a true statement?

Accepted Answer

High voltage electric repair should be left to those who are properly trained because it involves significant risks and requires specialized knowledge to ensure safety.

Question 15
