This height is typically recommended for safety reasons, as it provides a sufficient barrier to prevent falls or accidents. The intermediate rail and posts are also important components of the railing system, providing additional support and stability.

  • 7.

    • A.

      Good housekeeping

    • B.

      Install more light curtains

    • C.

      Fines for not cleaning up your workstation

    • D.

      Round-Robin system

    Correct Answer
    A. Good housekeeping
    Explanation
    Good housekeeping is the first step in reducing trips and falls in any workplace. This involves keeping the workplace clean, organized, and free from hazards such as clutter, spills, and obstacles. By maintaining good housekeeping practices, employees can prevent accidents and injuries caused by slips, trips, and falls. Regular cleaning, proper storage of materials, and clear pathways contribute to a safe working environment. Installing more light curtains, implementing fines for not cleaning up workstations, or using a round-robin system may not directly address the root cause of trips and falls, which is poor housekeeping.

    Rate this question:

  • 8. 

    Why are toe boards required in addition to guardrails in many industrial situations?

    • A.

      To prevent objects from falling onto workers below.

    • B.

      Toe boards serve to delineate the outer edge of the surface via contact rather than vision.

    • C.

      Toe boards add structural rigidity to guardrails.

    • D.

      Toe boards allow ladders to be “toed-in” for support when work must be performed above the surface.

    Correct Answer
    A. To prevent objects from falling onto workers below.
    Explanation
    Toe boards are required in addition to guardrails in many industrial situations to prevent objects from falling onto workers below. This is because toe boards serve as a physical barrier that blocks the edge of the surface, preventing any objects from accidentally rolling or falling off. By providing this extra layer of protection, toe boards help to ensure the safety of workers by minimizing the risk of objects causing injury or damage when working at heights.
