  5. Question: Which of the following is a common hazard associated with trenching and excavation work?
    • A) Overhead lighting
    • B) Heat exhaustion
    • C) Cave-ins
    • D) Loud noises
    Answer: C) Cave-insExplanation: Cave-ins are a significant risk associated with trenching and excavation work. Protective measures such as trench boxes or shoring must be implemented to prevent collapse-related accidents.
  6. Question: What should workers do if they encounter damaged or defective personal protective equipment (PPE)?
    • A) Continue using it until the end of the shift
    • B) Report it immediately and replace it
    • C) Ignore it if it doesn’t impact safety directly
    • D) Modify it to make it usable
    Answer: B) Report it immediately and replace itExplanation: Any damaged or defective Personal Protective Equipment (PPE) should be reported immediately and replaced to ensure worker safety. Continued use of compromised PPE can increase the risk of injuries.
  7. Question: Which type of scaffolding provides the most maneuverability on a construction site?
    • A) Single pole scaffold
    • B) Suspended scaffold
    • C) Mobile scaffold
    • D) Cantilever scaffold
    Answer: C) Mobile scaffoldExplanation: Mobile scaffolding offers easy mobility and flexibility on construction sites, allowing workers to move it to various locations as needed.
  8. Question: What is the purpose of a “confined space entry permit” in construction safety?
    • A) To allow unrestricted access to confined spaces
    • B) To document hazards and safety measures for entering confined spaces
    • C) To limit the number of workers in confined spaces
    • D) To ignore safety protocols in confined spaces
    Answer: B) To document hazards and safety measures for entering confined spacesExplanation: The permit documents hazards and safety measures required for entry into confined spaces, ensuring proper safety protocols are followed before accessing such areas.
  9. Question: Which type of hazard does “struck-by” refer to in construction safety?
    • A) Falls
    • B) Being hit by moving objects
    • C) Electrical shocks
    • D) Exposure to hazardous chemicals
    Answer: B) Being hit by moving objectsExplanation: “Struck-by” refers to the risk of being hit by moving objects on a construction site, highlighting the importance of wearing appropriate protective gear and being aware of surroundings.
  10. Question: What is the purpose of conducting regular safety toolbox talks on a construction site?
    • A) To discuss the latest sports newsB) To educate workers about safety procedures and hazardsC) To promote sales of construction equipmentD) To plan social events for workers
    Answer: B) To educate workers about safety procedures and hazardsExplanation: Toolbox talks are conducted to educate workers about safety procedures, potential hazards, and best practices on-site, fostering a safety-oriented work environment.
