  1. A confined space is classified as 'permit-required' under OSHA 29 CFR 1910.146 if it has which characteristic?

    Answer: A space with a potential for a hazardous atmosphere or engulfment hazard

    A permit-required confined space has one or more serious hazards: hazardous atmosphere, engulfment risk, converging walls, or any recognized serious safety/health hazard.

  2. When conducting industrial hygiene air monitoring for a volatile hazardous substance, which sampling method collects a grab sample?

    Answer: Evacuated canister or Tedlar bag filled instantaneously

    Grab samples capture air instantaneously using evacuated canisters or Tedlar bags and represent conditions at a single point in time.

  3. What is the primary purpose of a Job Hazard Analysis (JHA) in occupational health and safety?

    Answer: To systematically identify hazards associated with each step of a job task

    A JHA breaks a job into steps, identifies hazards at each step, and recommends controls before work begins — a proactive prevention tool.

  4. Under the hierarchy of controls, which control measure is considered MOST effective for reducing occupational hazards?

    Answer: Elimination of the hazard

    Elimination — physically removing the hazard — is the most effective control because it prevents exposure entirely rather than managing it.

  5. NIOSH recommends what maximum recommended weight for a manual lifting task under ideal conditions (optimal frequency, coupling, and geometry)?

    Answer: 23 kg (51 lbs)

    NIOSH's lifting equation sets 23 kg (51 lbs) as the recommended weight limit (RWL) under ideal conditions, with multipliers reducing this for adverse conditions.

  6. Which chemical route of exposure bypasses many of the body's defense mechanisms and allows direct systemic absorption?

    Answer: Dermal absorption through intact skin

    Dermal absorption allows chemicals to enter the bloodstream directly through the skin, bypassing gastrointestinal and hepatic first-pass metabolism.

  7. What does OSHA's 'General Duty Clause' (Section 5(a)(1) of the OSH Act) require of employers?

    Answer: Provide a workplace free from recognized hazards likely to cause death or serious harm

    The General Duty Clause requires employers to provide a workplace free from recognized serious hazards even when no specific OSHA standard applies.
