  1. What is the maximum permissible noise exposure for a construction worker at 95 dBA without hearing protection under OSHA standards?

    Answer: 4 hours

    OSHA 1926.52 allows a maximum of 4 hours of exposure at 95 dBA without engineering controls or hearing protection in construction.

  2. During a toolbox talk, a foreman asks which class of hard hat protects against high-voltage electrical hazards up to 20,000 volts. The correct answer is:

    Answer: Class B

    Class B (Type II) hard hats are tested to protect against high-voltage electrical hazards up to 20,000 volts.

  3. A CHST is implementing a hierarchy of controls for a struck-by hazard from overhead crane operations. Which control should be implemented FIRST?

    Answer: Eliminate overhead lifting by using ground-level assembly

    Elimination is the highest and most effective level of the hierarchy of controls, removing the hazard entirely rather than mitigating exposure to it.

  4. Which document establishes minimum safety and health program requirements that are widely referenced by safety professionals and used as a framework for construction SMS?

    Answer: ANSI/ASSP Z10

    ANSI/ASSP Z10 is the American national standard for Occupational Health and Safety Management Systems, widely used as a construction SMS framework.

  5. Under 29 CFR 1926.502, what is the maximum force a personal fall arrest system must be able to withstand during a fall arrest event?

    Answer: 5,000 pounds

    OSHA requires anchorage points for personal fall arrest systems to support at least 5,000 pounds per attached worker.

  6. A safety audit of scaffolding reveals planks with a working load of 50 psf. If a scaffold platform is 5 feet wide and 10 feet long, what is the maximum load the platform should support?

    Answer: 2,500 lbs

    50 psf × (5 ft × 10 ft) = 50 × 50 = 2,500 lbs maximum allowable load for this scaffold platform.

  7. When conducting a pre-task safety analysis for hot work near flammable materials, a CHST should verify that a fire watch remains on duty for at least how long after welding is complete?

    Answer: 30 minutes

    NFPA 51B and most hot work permit programs require a fire watch to remain for a minimum of 30 minutes after hot work is completed.
