  1. Which OSHA standard specifically governs excavation and trenching safety on field construction sites?

    Answer: 29 CFR 1926.650-.652

    OSHA 29 CFR 1926.650-.652 (Subpart P) covers excavations, trenching, and shoring requirements for construction sites.

  2. A field builder notices a trench is 6 feet deep with no protective system in place. What is the correct immediate action?

    Answer: Stop work and evacuate workers from the trench

    OSHA requires a protective system (sloping, shoring, or shielding) for any trench 5 feet or deeper; workers must be evacuated until it is in place.

  3. What does the term 'competent person' mean in the context of OSHA excavation standards?

    Answer: Someone capable of identifying hazards and authorized to take corrective action

    OSHA defines a competent person as one who can identify existing and predictable hazards and has authority to eliminate them.

  4. Under NFPA 70E, an arc flash boundary is established to protect workers from which hazard?

    Answer: Incident energy that could cause a second-degree burn

    The arc flash boundary marks the distance at which incident energy equals 1.2 cal/cm², the threshold for a curable second-degree burn.

  5. Which document must be completed before workers begin hot work (welding/cutting) on a field construction project?

    Answer: Hot work permit

    A hot work permit authorizes and controls ignition-source activities, ensuring fire watch and extinguisher requirements are met beforehand.

  6. What is the minimum safe approach distance for an unqualified worker near an energized overhead power line operating at 50 kV?

    Answer: 10 feet

    OSHA 1926.1408 requires a 10-foot minimum clearance for voltages up to 50 kV for unqualified workers.

  7. A field builder discovers a spill of a hazardous chemical on site. According to HAZCOM standards, where should they first look for handling instructions?

    Answer: The Safety Data Sheet (SDS) for that chemical

    OSHA's Hazard Communication Standard (29 CFR 1910.1200) requires SDS documents to be accessible on-site for every hazardous chemical in use.
