  1. When conducting a Job Hazard Analysis (JHA), which step comes FIRST?

    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. A worker is exposed to a noise level of 95 dBA for 4 hours per day. According to OSHA's permissible exposure limits, this situation:

    Answer: Exceeds the PEL and requires immediate controls

    OSHA's PEL for 95 dBA is 4 hours, so 4 hours of exposure at 95 dBA exactly meets but does not exceed the PEL; however, if combined with other noise sources, it could exceed it.

  3. Which hierarchy of controls option is considered most effective for eliminating workplace hazards?

    Answer: Elimination

    Elimination physically removes the hazard from the workplace and is the most effective control method in the hierarchy.

  4. Under OSHA's Lockout/Tagout standard (29 CFR 1910.147), an 'authorized employee' is defined as one who:

    Answer: Locks out or tags out machines to perform servicing

    An authorized employee is specifically the person who locks out or tags out the machine or equipment to perform service or maintenance.

  5. What does the term 'residual risk' mean in safety management?

    Answer: Risk that remains after all feasible controls have been implemented

    Residual risk is the risk that remains after all practicable hazard controls have been implemented and is accepted by management.

  6. A safety professional discovers that a confined space contains an oxygen concentration of 19.0%. This atmosphere is classified as:

    Answer: Oxygen deficient and potentially hazardous

    OSHA defines an oxygen-deficient atmosphere as one with less than 19.5% oxygen by volume, making 19.0% oxygen deficient.

  7. Which type of fire extinguisher is specifically appropriate for use on energized electrical equipment fires (Class C)?

    Answer: CO2 or dry chemical extinguisher

    CO2 and dry chemical extinguishers are rated for Class C fires because they are non-conductive and will not cause electrical shock.
