  1. The hierarchy of hazard controls lists controls in what order from most to least effective?

    Answer: Elimination → Substitution → Engineering controls → Administrative controls → PPE

    NIOSH's hierarchy of controls ranks from most effective (elimination) to least effective (PPE), guiding hazard control selection.

  2. A Job Hazard Analysis (JHA) or Job Safety Analysis (JSA) is most effective when:

    Answer: Developed by the supervisor and workers who perform the task

    JHAs are most effective when developed collaboratively with workers who actually perform the task, as they have firsthand knowledge of the hazards.

  3. An 'engineering control' for controlling a noise hazard would be:

    Answer: Installing sound-dampening enclosures around loud machinery

    Engineering controls physically modify the work environment to reduce hazard exposure — in this case, enclosing the noise source.

  4. When should a pre-task safety plan be reviewed on a construction site?

    Answer: Every morning at the beginning of each shift (toolbox talk)

    Pre-task safety briefings (toolbox talks) should occur at the start of each shift to address daily hazards specific to that day's work.

  5. The term 'near miss' in construction safety refers to:

    Answer: A close call where no injury or damage occurred but could have

    A near miss is an unplanned event that did not result in injury or damage but had the potential to do so under slightly different circumstances.

  6. OSHA's General Duty Clause (Section 5(a)(1) of the OSH Act) requires employers to:

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

    The General Duty Clause requires employers to address recognized hazards even when no specific OSHA standard covers that hazard.
