  1. What does the acronym IDLH stand for in industrial hygiene?

    Answer: Immediate Danger to Life and Health

    IDLH stands for Immediately Dangerous to Life or Health and represents the maximum airborne concentration from which a worker could escape in 30 minutes without irreversible health effects.

  2. A worker exposed to benzene over many years develops leukemia. This is an example of what type of health hazard?

    Answer: Chronic health effect

    Chronic health effects develop after prolonged or repeated exposure over a long period, such as benzene-induced leukemia.

  3. Which route of entry is typically the MOST common pathway for workplace chemical exposure?

    Answer: Inhalation

    Inhalation is the most common route of entry for workplace chemical hazards because workers breathe contaminated air continuously throughout their shift.

  4. What is the primary purpose of a Threshold Limit Value (TLV) as published by ACGIH?

    Answer: To define concentrations below which nearly all workers can be repeatedly exposed without adverse health effects

    ACGIH TLVs are occupational exposure guidelines representing conditions under which nearly all workers may be repeatedly exposed without adverse health effects.

  5. Which type of ventilation system captures contaminants at or near their source before they enter the workroom air?

    Answer: Local exhaust ventilation

    Local exhaust ventilation (LEV) captures airborne contaminants at the point of generation, preventing them from dispersing into the workplace.

  6. A safety supervisor notices workers experiencing headaches, dizziness, and nausea in an enclosed area. Which hazard should be suspected FIRST?

    Answer: Carbon monoxide poisoning

    Carbon monoxide is an odorless, colorless gas that causes headache, dizziness, and nausea and is a primary suspect in enclosed-space illness outbreaks.
