    (c) Staying out of the swing radius of cranes
    (d) Ensuring the operator has a clear view before signaling movement

    12. Why is visibility critical when working near moving vehicles?
    (a) It helps identify workers’ seniority

    (c) It improves air circulation on site
    (d) It reduces fatigue caused by glare

    True/False Questions

    13. True/False: Struck-by hazards occur only when an object falls from above.
    14. True/False: Powder-actuated tools can cause flying object hazards because their fasteners can penetrate wood, concrete, or steel.
    15. True/False: Windy conditions increase the risk of struck-by swinging object incidents.
    16. True/False: Wearing reflective high-visibility clothing is required for workers near public roadways.
    17. True/False: Hard hats must be replaced only when lost, not when damaged.
    18. True/False: Toeboards and guardrails should be used during overhead work to prevent tools and materials from falling.
    19. True/False: Employers are required to provide PPE, but workers must purchase replacements themselves.
    20. True/False: It is acceptable to use powder-actuated tools without training as long as they are inspected daily.
    21. True/False: Never position yourself between moving and fixed objects.
    22. True/False: Wearing high-visibility clothes near equipment/vehicles helps to prevent struck-by hazards.
    23. True/False: A worker inside the swing radius of a crane is safe as long as the operator is certified.
