CERTIFICATION EXAM PREP WITH COMPLETE EXAM QUESTIONS
AND CORRECT VERIFIED ANSWERS/ ALREADY GRADED A+
1. A construction employer is developing a comprehensive health and
safety program and wants to ensure that workers understand both their
responsibilities and the procedures they must follow when hazards are
identified. Which approach is most effective?
A. Provide safety information only after an incident occurs
B. Establish clear policies, hazard-control procedures, training
requirements, reporting processes, and worker responsibilities
C. Allow each worker to determine independently which safety
procedures are necessary
D. Focus the program primarily on completing paperwork for regulatory
purposes
Answer: B
Rationale: An effective health and safety program establishes clear

2. During a site inspection, an NCSO observes an unguarded opening in
a work surface through which a worker could fall. What should be the
immediate priority?
A. Document the opening and wait until the next scheduled inspection
B. Identify the hazard, prevent exposure to workers, and ensure an
appropriate control is implemented
C. Ask workers to be more careful around the opening
D. Continue the inspection before addressing the hazard
Answer: B
Rationale: A serious fall hazard requires immediate action to prevent
worker exposure while an effective control is established.
3. A supervisor tells workers to wear personal protective equipment
instead of installing a physical guard around a hazardous machine.
Which principle of the hierarchy of controls is being overlooked?
A. Elimination and engineering controls should generally be considered
before relying on PPE
B. PPE is always more effective than engineering controls
C. Administrative controls should never be used
D. Hazard identification should occur only after an incident
,3|Page
Answer: A
Rationale: The hierarchy of controls prioritizes eliminating or reducing
hazards at their source before relying on administrative measures or
PPE.
4. A worker reports that a power tool has a damaged electrical cord.
What is the most appropriate response?
A. Allow continued use if the worker is experienced
B. Remove the defective tool from service and ensure it is appropriately
repaired or replaced
C. Cover the damaged section with any available material
D. Permit use only during daylight hours
Answer: B
Rationale: Defective equipment should be removed from service until it
has been properly repaired or replaced.
5. Before beginning a high-risk construction activity, the employer
conducts a hazard assessment and identifies several potential hazards.
What is the primary purpose of this assessment?
A. To determine who should receive disciplinary action
, 4|Page
B. To identify hazards, evaluate associated risks, and establish
appropriate controls before workers are exposed
C. To replace all worker training
D. To document hazards only after they cause injuries
Answer: B
Rationale: Hazard assessment is a proactive process used to identify
hazards and determine appropriate controls before work begins.
6. A worker reports a near miss involving a falling object, but nobody
was injured. What should the employer do?
A. Ignore the event because there was no injury
B. Investigate the near miss to identify contributing factors and prevent
recurrence
C. Discipline the worker automatically
D. Record the event only if an injury occurs later
Answer: B
Rationale: Near misses provide valuable information about weaknesses
in hazard controls and should be investigated to prevent future
incidents.
