SAF Personal Protective Equipment 3

Question 1

Which PPE element is considered the LAST resort in the hierarchy of hazard controls?

Accepted Answer

Personal protective equipment

Answer

PPE sits at the bottom of the hierarchy of controls because it does not eliminate the hazard—it only protects the individual worker from exposure.

Question 2

Safety footwear with an ASTM F2413 rating is tested for which primary hazard?

Accepted Answer

Compression and impact to the toe

Answer

ASTM F2413 establishes performance requirements for protective toe footwear, primarily testing resistance to impact and compression at the toe.

Question 3

An employee working near unguarded electrical equipment energized above 50 volts should wear gloves rated for at least which class?

Accepted Answer

Class 1 or higher, depending on voltage

Answer

OSHA and NFPA 70E require rubber insulating gloves rated at the appropriate class for the voltage present; Class 1 protects up to 7,500 volts AC.

Question 4

What does an APF (Assigned Protection Factor) of 10 for a half-face air-purifying respirator mean?

Accepted Answer

The wearer can work in atmospheres up to 10 times the PEL

Answer

An APF of 10 means the respirator reduces the wearer's exposure so they experience no more than one-tenth of the ambient contaminant concentration.

Question 5

Hearing protection with an NRR of 30 dB is used in an environment measured at 100 dBA. What is the estimated protected exposure level using the OSHA field-use method?

Accepted Answer

85 dBA

Answer

OSHA's field-use method derates NRR by 50%: 100 − (30/2) = 100 − 15 = 85 dBA, which meets the OSHA 90 dBA PEL but approaches the action level.
