Accepted Answer

People with pacemakers should avoid working on or near strong magnets, as they can interfere with the functioning of the pacemaker.

Question 2

A class C type fire extinguisher can be used on what type of fires?

Accepted Answer

Class C fire extinguishers are designed for fires involving electrical equipment or wiring.

Question 3

Technician A removes a battery by disconnecting the positive cable first. Technician B uses a battery lifting strap to lift the battery out of the vehicle. Who is correct?

Accepted Answer

Technician B is correct because using a battery lifting strap is a safe method to lift a battery out of a vehicle. Disconnecting the negative cable first, not the positive, is the recommended practice to prevent short circuits.

Question 4

Which of the following  extinguishers  is recommended to put out electrical fires?

Accepted Answer

Type C extinguishers are specifically designed for electrical fires, as they use non-conductive substances to extinguish the fire without the risk of electric shock.

Question 5

Ergonomic hazards are being discussed. Technician A says they impede normal body position and motion. Technician B says they are the result of noise or vibrations. Who is correct?

Accepted Answer

Technician A is correct because ergonomic hazards indeed impede normal body position and motion, affecting musculoskeletal health. Technician B is incorrect because noise or vibrations are considered physical hazards, not ergonomic.

Question 6

Failure to report a hazardous waste spill can result in a penalty of ______.

Accepted Answer

Failure to report a hazardous waste spill can result in both financial penalties and imprisonment, indicating that both a fine (such as $10,000) and a term in jail (such as one year) can be imposed as penalties.

Question 7

Technician A says OSHA regulates vehicle emission standards. Technician B says the Environmental Protection Agency [EPA] regulates the disposal of hazardous wastes. Who is correct?

Accepted Answer

The Environmental Protection Agency (EPA) is responsible for regulating the disposal of hazardous wastes, not OSHA. OSHA focuses on workplace safety and health, not vehicle emission standards.

Question 8

The high voltage electrical cables (harness cover)of a hybrid vehicle are colored ______.

Accepted Answer

The high voltage electrical cables in a hybrid vehicle are typically colored orange to indicate caution due to the high voltage they carry. This color coding helps in identifying and avoiding potential electrical hazards during maintenance or emergency services.

Question 9

Technician A says used engine oil may be burned in an EPA approved commercial space heater. Technician B says oil filters should be thrown in the trash immediately after being removed from the vehicle. Who is correct?

Accepted Answer

Technician A is correct because used engine oil can indeed be burned in an EPA-approved commercial space heater as a form of recycling and energy recovery. Technician B is incorrect because oil filters should not be thrown in the trash immediately after removal; they often contain residual oil and should be properly drained and recycled according to local regulations to prevent environmental contamination.

Question 10

When lifting heavy parts, Technician A twists at the waist to change direction. Technician B turns his whole body using his feet. Who is correct?

Accepted Answer

Twisting at the waist while lifting heavy objects can lead to back injuries. It is safer to turn the whole body using the feet, as this method reduces strain on the back.

Question 11

Technician A says all hazardous wastes must be properly labeled and sealed and kept in the recommended containers. Technician B says to reduce the amount of hazardous waste generated by a shop, parts should be initially cleaned with used solvent, then a second time with clean solvent. Who is correct?

Accepted Answer

Both technicians are correct. Technician A is correct because hazardous wastes must indeed be properly labeled, sealed, and stored in recommended containers to ensure safety and compliance with regulations. Technician B is correct in suggesting that using used solvent first for initial cleaning followed by a clean solvent for a second cleaning can help reduce the overall amount of hazardous waste generated by a shop, promoting more sustainable practices.

Question 12

An MSDS is being discussed. Technician A says it is the shop's responsibility to develop it. Technician B says it must be readily available to all shop personnel. Who is correct?

Accepted Answer

The responsibility to develop an MSDS (Material Safety Data Sheet) falls on the manufacturer of the product, not the shop. However, it is indeed the shop's responsibility to ensure that the MSDS is readily available to all personnel, making Technician B correct.

Question 13

Federal Right-to-Know laws concern ______.

Accepted Answer

Federal Right-to-Know laws specifically address the hazards associated with chemicals used in the workplace, ensuring that employees are informed about the dangers of chemicals they may be exposed to while performing their job duties.

Question 14

Technician A says that you wear shoes with nonslip soles in the shop. Technician B says safety shoes have steel plates built into the toe and shank to protect your feet. Who is correct?

Accepted Answer

Both statements are correct. Nonslip soles help prevent slips and falls in the shop, and safety shoes often have steel plates for added protection.

Question 15

What type of gloves should be worn when working on the electrical system of a hybrid vehicle?

Accepted Answer

Lineman's gloves are specifically designed for electrical work, providing the necessary insulation to protect against electric shock, which is crucial when working on the electrical systems of hybrid vehicles.

Question 16

Technician A says carbon monoxide has an odor similar to burnt oil. Technician B says a volatile liquid evaporates slowly. Who is correct?

Accepted Answer

Carbon monoxide is odorless, making it particularly dangerous because it's hard to detect without a proper detector. A volatile liquid, by definition, evaporates quickly, not slowly.

Question 17

Technician A uses a respiratory mask [respirator] when working with solvents and painting. Technician B uses a mask [particle mask] when working on or handling parts made with asbestos. Who is correct?

Accepted Answer

Both technicians are correct in their use of protective masks. Technician A uses a respirator for protection against solvent vapors and paint fumes, which is appropriate for those hazards. Technician B uses a particle mask for asbestos, which helps protect against inhaling asbestos fibers.

Question 18

Battery charging is being discussed. Technician A says the charger should be turned on before connecting the charger cables to the battery terminals. Technician B says a battery with frozen electrolyte should be charged for thirty minutes or until the electrolyte melts. Who is correct?

Accepted Answer

Turning on the charger before connecting it to the battery can cause sparks, which is dangerous. Charging a battery with frozen electrolyte can cause the battery case to rupture or explode, so it should not be charged until it has thawed.

Question 19

Technician A says vehicle refrigerants must be recovered and recycled. Technician B says splash goggles should be worn when servicing an air-conditioning system. Who is correct?

Accepted Answer

Both statements are correct. Vehicle refrigerants must indeed be recovered and recycled to prevent environmental damage and comply with regulations. Wearing splash goggles is a safety measure to protect the eyes from potential harm when servicing an air-conditioning system.

Question 20
