  1. Under OSHA 1926.502(d), when a worker is using a body harness in a personal fall arrest system, the total fall distance (including deceleration) must not exceed:

    Answer: 12 feet

    The total fall distance including deceleration distance cannot exceed 12 feet under OSHA 1926.502(d).

  2. Which document establishes the minimum safety and health requirements for a permit-required confined space entry program?

    Class D fires involving combustible metals like magnesium require specialized dry powder agents such as Met-L-X, not standard extinguishers.

  4. What is the OSHA permissible exposure limit (PEL) for silica (respirable crystalline) in construction under 29 CFR 1926.1153?

    Answer: 50 µg/m³ as an 8-hour TWA

    OSHA's PEL for respirable crystalline silica in construction is 50 µg/m³ as an 8-hour time-weighted average.

  5. A safety technician observes workers using a powder-actuated tool without wearing hearing protection. Under OSHA standards, this tool requires hearing protection because noise levels typically exceed:

    Answer: 90 dBA

    OSHA's 1926.52 action level is 90 dBA for an 8-hour TWA; powder-actuated tools often exceed this threshold.

  6. What is the minimum distance a spoil pile must be kept from the edge of an excavation under OSHA 1926.651?

    Answer: 2 feet

    OSHA requires spoil piles to be placed at least 2 feet from the edge of an excavation to prevent cave-ins.

  7. During a toolbox talk on struck-by hazards, which control is considered most effective for protecting workers from swing radius hazards when a crane is operating?

    Answer: Establishing and enforcing physical barricades around the swing radius

    Physical barricades prevent unauthorized entry into the swing radius, eliminating the exposure rather than relying on worker behavior.
