  1. When conducting a Job Hazard Analysis (JHA), what is the FIRST step a supervisor should take?

    Answer: Select the job to be analyzed

    The first step in a JHA is selecting the job to be analyzed, typically prioritizing jobs with high injury rates or severe potential consequences.

  2. Which type of hazard control is considered MOST effective according to the hierarchy of controls?

    Answer: Elimination

    Elimination — physically removing the hazard — is the most effective control because it completely removes the risk from the workplace.

  3. A construction worker notices a trench wall showing signs of cracking and bulging. This is an example of which type of hazard?

    Answer: Physical hazard

    Cracking and bulging trench walls indicate an imminent cave-in, which is a physical hazard involving structural instability.

  4. What does the term 'near miss' mean in the context of construction safety?

    Answer: An unplanned event that did not result in injury but had the potential to do so

    A near miss is an unplanned event with potential to cause injury or damage but did not — it is a critical leading indicator for preventing future accidents.

  5. Which federal standard requires construction employers to have a written Hazard Communication program when hazardous chemicals are present?

    Answer: 29 CFR 1926.59

    29 CFR 1926.59 (Hazard Communication) requires construction employers to maintain a written HazCom program and ensure workers are informed about chemical hazards.

  6. A supervisor identifies a hazard that cannot be immediately eliminated. What is the BEST immediate action?

    Answer: Implement interim controls and warn affected workers while pursuing a permanent fix

    When a hazard cannot be immediately eliminated, supervisors should implement interim controls and communicate the hazard to workers while working toward a permanent solution.

  7. What is the purpose of a 'toolbox talk' related to hazard identification?

    Answer: To brief workers on specific hazards and safe practices before starting daily work

    Toolbox talks are brief pre-work safety meetings used to alert workers to daily hazards, reinforce safe practices, and promote a safety culture on the jobsite.
