1. What is the primary purpose of a job hazard analysis (JHA)?
A) To create a project budget
B) To identify potential hazards and control measures
C) To determine the required tools and equipment for the job
D) To select workers for the job
Answer: B) To identify potential hazards and control measures
Rationale: A JHA helps identify hazards that could cause injury or harm on a construction site
and outlines the necessary control measures to mitigate those risks.
2. Which of the following is an essential part of a construction safety program?
A) Providing employees with personal protective equipment (PPE) only
B) Ensuring all workers are trained in safety procedures
C) Ignoring worker input on safety concerns
D) Focusing solely on safety inspections
Answer: B) Ensuring all workers are trained in safety procedures
Rationale: Effective safety programs require worker involvement, including safety training, to
ensure workers understand risks and know how to mitigate them.
3. What does the acronym PPE stand for?
A) Proper Personnel Equipment
B) Personal Protective Equipment
C) Pre-project Evaluation
D) Personal Project Equipment
Answer: B) Personal Protective Equipment
Rationale: PPE refers to gear such as helmets, gloves, goggles, and safety harnesses designed to
protect workers from injury on construction sites.
4. Which of the following is NOT a common hazard found on construction sites?
A) Falling debris
B) Slips, trips, and falls
C) Noise-induced hearing loss
D) Excessive lighting
,Answer: D) Excessive lighting
Rationale: Excessive lighting is typically not considered a hazard. The other options (falling
debris, slips, trips, and falls, noise) are common hazards in construction environments.
5. Which of the following is a key responsibility of the National Construction
Safety Officer (NCSO)?
A) To perform all on-site work activities
B) To enforce safety rules and regulations
C) To develop marketing strategies for the construction company
D) To supervise workers directly
Answer: B) To enforce safety rules and regulations
Rationale: The NCSO is responsible for overseeing safety policies, enforcing safety rules, and
ensuring compliance with safety regulations on construction sites.
6. Which regulation requires employers to protect workers from falling when
working at heights?
A) Occupational Health and Safety Act (OHSA)
B) Construction Safety Regulations (CSR)
C) National Building Code (NBC)
D) Workers Compensation Act
Answer: A) Occupational Health and Safety Act (OHSA)
Rationale: The OHSA outlines requirements for fall protection, ensuring that workers are
provided with appropriate safety measures when working at heights.
7. When should safety meetings be held on a construction site?
A) Only when a serious incident occurs
B) At the start of every shift and as necessary
C) Only when new workers are hired
D) When the weather is unsafe
Answer: B) At the start of every shift and as necessary
Rationale: Safety meetings, such as toolbox talks, are typically held at the beginning of shifts
and whenever necessary to address new risks or incidents.
, 8. What is the purpose of a safety data sheet (SDS)?
A) To record employees' safety performance
B) To provide information on how to safely store materials
C) To offer details on hazardous chemicals used on-site
D) To monitor the weather conditions
Answer: C) To offer details on hazardous chemicals used on-site
Rationale: An SDS provides information on the handling, storage, hazards, and first aid
measures related to chemicals used on-site.
9. Which of the following is the most effective control for preventing accidents
related to electrical hazards on construction sites?
A) Using proper PPE only
B) De-energizing equipment when not in use
C) Installing warning signs around electrical panels
D) Providing training for workers
Answer: B) De-energizing equipment when not in use
Rationale: De-energizing electrical equipment eliminates the risk of electrocution. While other
measures are also important, this is the most effective control.
10. Which of the following is a major cause of falls in the construction industry?
A) Lack of proper signage
B) Inadequate lighting
C) Poor housekeeping
D) Lack of insurance coverage
Answer: C) Poor housekeeping
Rationale: Poor housekeeping, such as scattered debris, unmarked hazards, and cluttered
walkways, is a common cause of falls on construction sites.
11. What is a critical factor in ensuring proper use of scaffolding on construction
sites?
A) Ensuring scaffolds are erected by untrained workers
B) Ensuring scaffolds are regularly inspected for safety
A) To create a project budget
B) To identify potential hazards and control measures
