Question 1: Which of the following DOES NOT play a key role in figuring out how an electrocution event may affect a worker?
- The amount of electrically resistant material present in work boots and work gloves (Correct answer)
- The length of time an exposure to electricity occurs
- The path through the body the current takes
- The amount of electrical current passing through the body
Correct answer: The amount of electrically resistant material present in work boots and work gloves
The amount of current that flows through the body, the amount of time that a person is exposed to the current, and the precise direction the current follows all play a role in how an electrocution occurrence turns out.
Question 2: When workers are exposed to noise levels above an eight-hour time-weighted average of _________, OSHA regulation 29 CFR 1926.52 (Occupational Noise Exposure) requires the implementation of a hearing conservation program.
- 95 decibels (dB)
- 90 decibels (dB) (Correct answer)
- 75 decibels (dB)
- 60 decibels (dB)
Correct answer: 90 decibels (dB)
According to 29 CFR 1926.52, a Hearing Conservation Program, utilizing engineering and administrative controls, must be in place when the eight-hour time-weighted average of noise exceeds 90 dB.
Question 3: Which of the following is the maximum asbestos fiber concentration for an eight-hour exposure allowed by 29 CFR 1926.1101?
- 10 fibers per cubic centimeter of air
- 100 fibers per cubic centimeter of air
- 0.1 fibers per cubic centimeter of air (Correct answer)
- 0.25 fibers per cubic centimeter of air
Correct answer: 0.1 fibers per cubic centimeter of air
According to 29 CFR 1926.1101, an employer is required to make sure that no employee is exposed to more than 0.1 fibers of asbestos per cubic centimeter of air over the course of an eight-hour shift.
Question 4: The distance between landing platforms on a fixed ladder using a cage or well with several ladder sections shall be __________, in accordance with OSHA regulation 29 CFR 1926.1053.
- no greater than 50 feet (Correct answer)
- no greater than 36 feet
- no greater than 30 feet
- no greater than 24 feet
Correct answer: no greater than 50 feet
A fixed ladder using a cage or well with numerous ladder sections is required to provide landing platforms at a maximum distance of 50 feet, according to OSHA regulation 29 CFR 1926.1053(a)(19)(iii).
Question 5: How long must an employer retain records regarding a chemical to which an employee was exposed and for which they received medical care?
- Ten (10) years
- Thirty (30) years (Correct answer)
- Three (3) years
- Until the chemical is no longer used by the company
Correct answer: Thirty (30) years
Employers are required to retain Safety Data Sheets (SDSs) for any chemicals used in their work under the Hazard Communication Standard (29 CFR 1910.1200, as referenced in 29 CFR 1926.59). However, if a worker is exposed to a chemical and receives medical attention, the employer is still required to preserve records about that chemical for thirty (30) years beyond the date of the employee's exposure since some consequences of chemical exposure are latent, meaning they do not manifest themselves until after some amount of time has elapsed. The SDS is optional for employers to keep, but they are required by law to at the very least preserve a record of the chemical to show where and when it was used.
Question 6: Which of the following types of PPE is best for shielding the eyes from dust in a construction environment?
- Welding goggles
- Face shields
- Safety glasses
- Safety goggles (Correct answer)
Correct answer: Safety goggles
Safety glasses don't offer as much protection from airborne eye threats such dust as goggles that seal with the forehead and temples. They can offer protection from projectiles that are launched into the air if they are approved for impact protection.
Question 7: To make sure they are providing the necessary protection against electrical shock, how frequently must electrical insulating gloves be tested?
- As deemed appropriate by visual inspection
- Annually
- Biweekly
- Every six months (Correct answer)
Correct answer: Every six months
Electrical insulating gloves must undergo testing every six months in accordance with 29 CFR 1926.97.
