Read the first 7 Occupational Health and Industrial Hygiene flashcards as text

  1. Under OSHA's Hazard Communication Standard (HCS), Safety Data Sheets must contain how many standardized sections?

    Answer: 16

    The GHS-aligned HCS requires 16 standardized sections on every SDS to ensure consistent hazard information worldwide.

  2. What is the primary purpose of conducting a job hazard analysis (JHA) before assigning a new task to workers?

    Answer: To identify hazards and determine protective measures before the task begins

    A JHA systematically breaks down a job into steps, identifies associated hazards, and recommends controls, preventing incidents proactively.

  3. Which health effect is most closely associated with chronic inhalation of crystalline silica dust?

    Answer: Silicosis

    Silicosis is the irreversible fibrotic lung disease caused by prolonged inhalation of respirable crystalline silica particles.

  4. An industrial hygienist measures a TWA of 0.08 mg/m³ for respirable crystalline silica. OSHA's PEL (as a TWA) is 0.05 mg/m³. What must the employer do first?

    Answer: Implement feasible engineering and work-practice controls

    When exposure exceeds the PEL, OSHA's silica standard requires employers to first use feasible engineering and work-practice controls before relying on respirators.

  5. Which parameter is measured by a direct-reading photoionization detector (PID)?

    Answer: Volatile organic compound concentration

    PIDs use UV light to ionize gas molecules and measure the resulting current, making them ideal for detecting and quantifying VOCs.

  6. What does the term 'half-life' mean in the context of occupational toxicology?

    Answer: The time required for half the absorbed dose of a substance to be eliminated from the body

    Biological half-life describes how quickly the body clears a toxicant, which determines how long a substance accumulates during repeated exposures.

  7. Which OSHA record-keeping form is used to record each individual work-related injury or illness case?

    Answer: OSHA 301

    OSHA Form 301 (Injury and Illness Incident Report) captures the details of each individual case recorded on the OSHA 300 Log.
