2.

Gasoline should always be stored in a closed container.

True
False

Correct Answer

A. True

Explanation

Gasoline should always be stored in a closed container to prevent evaporation, reduce the risk of fire or explosion, and minimize exposure to air and moisture which can degrade its quality. Storing gasoline in an open container increases the likelihood of fumes escaping, which can be highly flammable. Additionally, exposure to air and moisture can cause gasoline to oxidize and become less effective as a fuel. Therefore, it is important to store gasoline in a closed container to ensure safety and maintain its quality.

Oily or dirty floors can cause people to_________________

Lose their tools
Dance
Fall

Correct Answer

A. Fall

Explanation

Oily or dirty floors can cause people to fall. When floors are oily or dirty, they become slippery and increase the risk of losing balance and falling. The lack of traction makes it difficult for people to maintain their footing, leading to accidents and potential injuries. Therefore, it is important to keep floors clean and free from oil or dirt to ensure the safety of individuals.

Power tools should not be operated without proper safety shrouds?

True
False

Correct Answer

A. True

Explanation

Power tools should not be operated without proper safety shrouds because safety shrouds are designed to protect the user from potential hazards such as flying debris, sparks, or accidental contact with the tool's moving parts. These shrouds act as a barrier between the user and the tool, reducing the risk of injuries. Operating power tools without safety shrouds can increase the chances of accidents and injuries, making it important to always use the appropriate safety equipment when using power tools.

Fire extinguishers are categorized by the type of fire they are designed to suppress.

True
False

Correct Answer

A. True

Explanation

Fire extinguishers are indeed categorized by the type of fire they are designed to suppress. Different types of fires require different extinguishing agents, as using the wrong type of extinguisher can be ineffective or even dangerous. Common types of fire extinguishers include those designed for Class A fires (ordinary combustibles like wood and paper), Class B fires (flammable liquids and gases), Class C fires (electrical fires), and Class K fires (cooking oils and fats). By categorizing fire extinguishers based on the type of fire, it ensures that the appropriate extinguishing agent is used to effectively suppress the fire.

Electrical malfunction is the most common cause of shop fires.

True
False

Correct Answer

A. True

Explanation

Electrical malfunction is a common cause of shop fires because faulty wiring, overloaded circuits, or malfunctioning electrical equipment can generate sparks or heat that can ignite flammable materials. Additionally, poor maintenance of electrical systems or improper installation can also increase the risk of electrical malfunctions and subsequent fires. Therefore, it is important for shop owners to regularly inspect and maintain their electrical systems to prevent potential fire hazards.

7.

Small engine ignition systems can produce more than 30,000 volts.

True
False

Correct Answer

A. True

Explanation

Small engine ignition systems can produce more than 30,000 volts. This is because ignition systems need a high voltage spark to ignite the air-fuel mixture in the engine's combustion chamber. The high voltage is necessary to create a strong spark that can jump the gap between the spark plug electrodes. Therefore, it is true that small engine ignition systems can produce more than 30,000 volts.

To prevent injury when working around small engines, avoid wearing_____________

Loose clothing
Jewelry
Neckties
All of the above

Correct Answer

A. All of the above

Explanation

When working around small engines, it is important to avoid wearing loose clothing, jewelry, and neckties. Loose clothing can get caught in the moving parts of the engine, leading to injury. Jewelry can also get caught or snagged, causing harm. Neckties pose a similar risk as they can become entangled in the engine. Therefore, to prevent injury, it is best to avoid wearing all of the mentioned items.

Carbon monoxide is both ____and

Red, blue
Pungent, void
Colorless, ordorless

Correct Answer

A. Colorless, ordorless

Explanation

Carbon monoxide is a colorless and odorless gas. This means that it does not have a distinct color that can be seen and it does not have a noticeable smell.

10.

A flammable liquid frequently used in the small engine shop is _____________

Oil
Gasoline
Mountain dew

Correct Answer

A. Gasoline

Explanation

Gasoline is a flammable liquid commonly used in small engine shops because it is the fuel that powers most small engines. It is highly volatile and ignites easily, making it suitable for use in engines. Oil, on the other hand, is not typically used as a fuel but rather as a lubricant in engines. Mountain Dew is a carbonated soft drink and has no relevance to small engine shops or flammable liquids.

OSHA establishes regulations for _____________.

Engine repair
Getting your driver's license
Safe work practices

Correct Answer

A. Safe work practices

Explanation

OSHA, which stands for Occupational Safety and Health Administration, is a regulatory agency in the United States that sets and enforces standards for workplace safety. They establish regulations to ensure safe work practices in various industries and workplaces. This includes guidelines for handling hazardous materials, using protective equipment, preventing accidents, and promoting overall safety in the workplace. Therefore, the correct answer for this question is safe work practices.

Never use compressed air to clean __ or _

Gears, motors
The classroom
Clothing, hair

Correct Answer

A. Clothing, hair

Explanation

Using compressed air to clean clothing or hair can be dangerous and potentially harmful. The high pressure of the air can cause injury to the skin or eyes, and can also force debris or particles deeper into the clothing or hair, making it more difficult to remove. It is recommended to use alternative methods, such as brushing or washing, to clean clothing and hair.

Always lift without your _____________.

Arms
Legs
Back
All of the above

Correct Answer

A. Legs

Explanation

When lifting heavy objects, it is important to use your legs rather than your back or arms. This is because the leg muscles are much stronger and more capable of handling the weight, while the back and arm muscles are more prone to injury. By using your legs to lift, you can distribute the weight evenly and reduce the strain on your back.

14.

Batteries produce __ when charging or discharging.

Oxygen sulfide
Hydrogen gas
Carbon monoxide

Correct Answer

A. Hydrogen gas

Explanation

Batteries produce hydrogen gas when charging or discharging because the chemical reactions that occur within the battery involve the movement of electrons. These reactions cause the breakdown of water molecules into hydrogen and oxygen ions. The hydrogen ions then combine to form hydrogen gas, which is released as a byproduct of the battery's operation.
