  1. When selecting gloves for protection against chemical hazards, what is the most important factor to consider?

    Answer: The chemical compatibility of the glove material with the specific substance

    Chemical compatibility must be verified because no single glove material protects against all chemicals, and an incompatible glove can degrade rapidly and allow exposure.

  2. ANSI/ISEA Z41 (now ASTM F2413) governs which category of personal protective equipment?

    Answer: Safety footwear including toe protection

    ASTM F2413 (formerly ANSI Z41) is the standard for performance requirements for protective footwear, including impact and compression resistance ratings.

  3. A full-body harness used in a personal fall arrest system must be inspected by a competent person:

    Answer: Before each use and after any fall event

    OSHA requires fall arrest equipment to be inspected before each use and immediately removed from service after any fall event, as internal damage may not be visible.

  4. Which OSHA standard requires that employees who use tight-fitting respirators pass a fit test before using the respirator in the workplace?

    Answer: 29 CFR 1910.134 – Respiratory Protection

    29 CFR 1910.134 requires fit testing for all tight-fitting respirators to ensure an adequate seal is achieved, protecting the wearer from airborne hazards.

  5. High-visibility safety apparel (HVSA) is classified under ANSI/ISEA 107. Which class is required for workers exposed to high-speed traffic environments such as highway construction zones?

    Answer: Class 3 — highest visibility for high-risk environments

    ANSI/ISEA 107 Class 3 provides the greatest amount of high-visibility material and retroreflectivity, required where workers are exposed to high-speed vehicle traffic.

  6. What distinguishes a Type I hard hat from a Type II hard hat?

    Answer: Type I only reduces force on the top of the head; Type II also protects the sides

    Type I hard hats only provide top-of-head impact protection, while Type II hard hats offer additional lateral impact protection to the sides of the head.

  7. When using a combination of hearing protectors (earplugs and earmuffs together), how is the effective NRR calculated?

    Answer: Add 5 dB to the higher NRR rather than adding both values together

    When dual hearing protection is used, OSHA and NIOSH recommend adding only 5 dB to the higher NRR value, as the skull itself becomes a sound conduction path limiting additional attenuation.
