A) 6 feet
B) 1 meter
C) 10 feet
D) 3 meters

Accepted Answer

OSHA regulations state that fall arrest systems must be used when working at heights of 6 feet or more above a lower level. Therefore, the correct answer is A.

Question 6

Accidents involving electricity can lead to burns and tissue damage or cardiac arrest.

Accepted Answer

Accidents involving electricity can cause burns and tissue damage due to thermal energy and can also cause cardiac arrest due to disruption of the heart's electrical activity.

Question 7

Smoking is the most common cause of residential fires.

Accepted Answer

Cooking is the most common cause of residential fires, not smoking.

Question 8

Electrical Shock occurs when a person becomes part of an electrical circuit.

Accepted Answer

Electrical shock occurs when a person becomes a part of an electrical circuit, which can happen when they come into contact with an electrical source while also touching the ground or other conductive material. This can lead to electric current passing through the person's body, which can cause injury or even death.

Question 9

The Occupational Safety and Health Act requires __________ to provide a safe and healthful workplace free of recognized hazards and to follow OSHA standards.
A) employers
B) bureau of workmens' compensation
C) OSHA
D) All of the above

Accepted Answer

The Occupational Safety and Health Act requires employers to provide a safe and healthful workplace free of recognized hazards and to follow OSHA standards. The Bureau of Workmens' Compensation is a state-run program that provides benefits to employees who are injured or become ill due to their job, but is not responsible for ensuring workplace safety. OSHA is a federal agency responsible for setting and enforcing safety standards, but it is not the party required to provide a safe workplace - that falls on the employer.

Question 10

Fires that involve fuels such as oil and gas are classified as Class __________ fires.
A) A
B) B
C) C
D) D

Accepted Answer

Class B fires involve flammable liquids and gases, such as gasoline, oil, and propane. Class A fires involve common combustibles like wood and paper, Class C fires involve electrical equipment, and Class D fires involve combustible metals.

Question 11

Outdated chemicals should be taken directly to a landfill.

Accepted Answer

Outdated chemicals should not be taken directly to a landfill as they can pose a risk to the environment and human health. They should be disposed of properly through hazardous waste collection or other specialized disposal methods.

Question 12

A(n) _____ is a device that will deenergize the circuit when a small electrical leak to the ground has been detected, thus preventing the flow of electricity to a receptacle.
A) PPE
B) ASTME
C) GFCI
D) AED

Accepted Answer

The device described in the question is a Ground Fault Circuit Interrupter (GFCI). Options A, B, and D are unrelated to the description provided.

Question 13

Fires that involve ordinary materials such as paper, cardboard, and wood are classified as Class __________ fires.
A) A
B) B
C) C
D) D

Accepted Answer

Class A fires involve ordinary combustible materials such as paper, wood, cardboard, and most plastics. These materials require a water or water-based extinguishing medium.

Question 14

When using a ladder on the job site, it should be made of __________.
A) metal amalgam
B) fiberglass
C) aluminum
D) Either A or B

Accepted Answer

Fiberglass ladders are non-conductive, making them a safer choice when working around electrical hazards. They are also lightweight and resistant to moisture, chemicals, and corrosion. Metal amalgam and aluminum ladders conduct electricity and can be dangerous if used improperly.

Question 15

Hard hats, ear protection, and eye protection are part of _____ intended to be worn by people at work.
A) ACME
B) OSHA
C) NIOSH
D) PPE

Accepted Answer

PPE stands for Personal Protective Equipment and includes items such as hard hats, ear protection, and eye protection that are intended to be worn by people at work for their safety. ACME is a brand and not related to workplace safety, while OSHA and NIOSH are government organizations that promote workplace safety but are not specifically related to PPE.

Question 16

This class involves energized electrical equipment. Class ________ fire extinguishers usually use a dry powder to smother the fire.
A) A
B) B
C) C
D) D

Accepted Answer

Class C fire extinguishers are designed for fires involving energized electrical equipment, where the use of a non-conductive extinguishing agent is necessary to prevent electrical shock. Dry powder is commonly used in these extinguishers to smother the fire without conducting electricity.

Question 17

Preventing accidents has a direct effect on the bottom line of a project.

Accepted Answer

Preventing accidents can reduce costs associated with injuries, damage to equipment or property, and delays in the project timeline. It can also improve worker morale and productivity.

Question 18

Ergonomic principles can reduce workplace accidents.

Accepted Answer

Ergonomic principles are designed to optimize the fit between the worker and their work environment, reducing the physical strain on the body and minimizing the risk of injury. By implementing ergonomic solutions, such as adjusting equipment and workstations, providing proper training and promoting good posture, workplaces can reduce the number of accidents and injuries.

Question 19

General safety principles can eliminate workplace accidents.

Accepted Answer

General safety principles can significantly reduce the risk of workplace accidents but cannot eliminate them entirely due to unforeseen variables and human error.

Question 20

Wooden or fiberglass ladders are safe when in contact with live electric wires.

Accepted Answer

Both wooden and fiberglass ladders are not safe when in contact with live electric wires. A non-conductive ladder, such as a fiberglass or wooden ladder, may reduce the danger of electrocution, but it is not entirely safe as it can still conduct electricity under certain conditions. It is recommended to use specialized non-conductive ladders made specifically for working around live electrical wires.
