  1. Under OSHA 1926.1431, what maximum angle from vertical is permitted when using a personnel platform suspended from a crane?

    Answer: 5 degrees

    OSHA 1926.1431 requires that a personnel platform (man basket) suspended from a crane shall not be tilted more than 5 degrees from level during lifting.

  2. What is the standard wall thickness designation system used for steel pipe in US construction specifications?

    Answer: Nominal Pipe Size (NPS) with Schedule numbers

    Steel pipe in US construction is specified using Nominal Pipe Size (NPS) combined with Schedule numbers (e.g., Schedule 40, 80) that define wall thickness.

  3. According to IBC (International Building Code) Chapter 33, when must a licensed engineer review and approve shoring and bracing plans for construction?

    Answer: Whenever shoring supports an occupied structure

    IBC Chapter 33 requires engineered shoring and bracing plans whenever construction operations could affect the stability of occupied or adjacent structures.

  4. Per OSHA 1926.602, what is required before operating heavy equipment (scrapers, loaders, dozers) near excavations on a construction site?

    Answer: A banksman/spotter must be present at all times

    OSHA 1926.602 requires that a spotter (banksman) be used to guide heavy equipment operators when working near excavations, drop-offs, or areas where visibility is limited.

    Answer: 25 feet

    NFPA 58 requires a 500-gallon LP-Gas container to be located at least 25 feet from buildings, property lines, and sources of ignition.

  6. What does the term 'design working life' refer to in structural engineering specifications for construction?

    Answer: The assumed period for which a structure is designed to perform its intended purpose

    Design working life is the assumed period during which a structure or component is intended to perform its required function without major repair, typically 50 years for buildings.

  7. According to OSHA 1926.859, what action must be taken before demolishing any structure that previously contained hazardous materials?

    Answer: Conduct a pre-demolition engineering survey and hazardous material assessment

    OSHA 1926.859 mandates an engineering survey and hazardous material assessment (including asbestos and lead) before any demolition work begins.
