  1. Under OSHA's Hazard Communication Standard (29 CFR 1910.1200), how many hazard categories does the GHS system define for flammable liquids?

    Answer: 4

    GHS classifies flammable liquids into 4 categories based on flash point ranges, with Category 1 being most hazardous (flash point below 23°C and boiling point ≤35°C).

  2. What standard governs the design and use of falsework (temporary support structures for concrete formwork) in the United States?

    Answer: ANSI A10.9

    ANSI A10.9 (Safety Requirements for Concrete and Masonry Work) covers falsework design, erection, use, and removal requirements on US construction sites.

  3. When is a Permit-to-Work system legally required on construction sites under OSHA regulations?

    Answer: For confined space entry, hot work, and lockout/tagout activities

    OSHA mandates written permit systems specifically for confined space entry (1926.1203), hot work, and energy control (lockout/tagout) procedures on construction sites.

  4. Per NFPA 241, what minimum fire extinguisher rating is required for general construction site use protecting combustible materials?

    Answer: 2-A

    NFPA 241 requires a minimum 2-A rated extinguisher for ordinary combustibles in construction areas, ensuring adequate extinguishing capacity.

  5. Under ASME B30.5, what is the maximum allowable wind speed for operating a mobile crane?

    Answer: 30 mph

    ASME B30.5 specifies that crane operations should cease when wind speeds exceed 30 mph, though manufacturer specifications may require lower limits.

  6. What does the 'competent person' designation mean under OSHA construction regulations?

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

    OSHA defines a 'competent person' as one capable of identifying existing and predictable hazards and who has authority to take prompt corrective measures to eliminate them.

  7. According to OSHA 1926.405, what is the maximum voltage allowed for temporary lighting circuits on construction sites without additional insulation requirements?

    Answer: 120V

    OSHA 1926.405 limits temporary lighting circuits to 120 volts for standard portable hand lamps and construction lighting applications.
