  1. What is the employer's responsibility regarding PPE under OSHA 29 CFR 1926.28?

    Answer: Employers must provide and ensure use of appropriate PPE at no cost to employees

    OSHA 1926.28 and the PPE payment rule (29 CFR 1910.132(h)) require employers to provide PPE at no cost to employees, except for safety-toed footwear, prescription safety glasses, and logging boots (which employers may require workers to provide).

  2. A worker is using a half-face air-purifying respirator (APR) with organic vapor (OV) cartridges in an environment with unknown contaminant concentration. Why is this potentially unsafe?

    Answer: APRs cannot be used when contaminant concentration is unknown or may exceed 10 times the PEL (IDLH or above)

    Air-purifying respirators require a known, non-IDLH atmosphere to be safely used. When concentrations are unknown, air-purifying respirators may not provide adequate protection — supplied-air or SCBA is required for unknown or IDLH atmospheres.

  3. Under OSHA's respiratory protection standard (29 CFR 1910.134), what must be included in a written respiratory protection program?

    Answer: Procedures for respirator selection, employee training, medical evaluation, fit testing, maintenance, and program evaluation

    OSHA 1910.134(c) requires a written respiratory protection program containing: selection procedures, medical evaluation requirements, fit testing procedures, use requirements, maintenance and care, training, and program effectiveness evaluation.

  4. A construction worker needs eye protection for grinding operations. Which eye protection is the MINIMUM required?

    Answer: Safety glasses with side shields meeting ANSI Z87.1

    For grinding, OSHA 1926.102 requires eye protection against flying particles. Safety glasses with side shields meeting ANSI Z87.1 are the minimum requirement for grinding, though goggles may be preferable for fine particle operations.

  5. What is the correct action if a hard hat sustains a significant impact, even if no visible damage is evident?

    Answer: Remove it from service and replace it — internal damage may compromise protection

    Hard hat shells can absorb impact energy through internal structural damage invisible to the naked eye. Any hard hat that sustains a significant impact must be removed from service and replaced, regardless of external appearance.

  6. A construction site supervisor is developing a heat stress prevention program. Which PPE consideration is MOST IMPORTANT when workers must wear extensive body-covering PPE (chemical suits, high-visibility vests, coveralls) in hot weather?

    Answer: Accounting for heat burden added by PPE in the heat stress assessment and implementing work-rest cycles

    PPE adds a metabolic heat burden (clothing heat correction factor) because it traps body heat and may impair sweat evaporation. Heat stress assessments using WBGT or heat index must account for PPE heat burden, and work-rest cycles must be adjusted accordingly.
