A health and safety professional is reviewing the concept of due diligence in
occupational health and safety. Which three factors contribute to demonstrating due
diligence?
a. Foreseeability, Preventability, and Control
b. Liability, Accountability, and Responsibility
c. Training, Supervision, and Monitoring
d. Compliance, Documentation, and Reporting
✔️ Correct Answer: A
Rationale:
Due diligence requires that a person does everything reasonable to prevent harmful
outcomes. The three key factors are foreseeability (the ability to anticipate hazards),
preventability (the ability to take action to prevent harm), and control (the ability to
influence or manage the situation). Option A is correct. Liability, accountability, training,
and documentation are related concepts but are not the three specific factors of due
diligence.
,A safety coordinator is calculating the Lost Time Frequency Rate (LTFR) for a company.
Which formula correctly calculates the LTFR?
a. (Lost time cases × 200,000) / Total employee hours of exposure
b. (Lost work days × 200,000) / Total employee hours of exposure
c. (Lost time cases + medical aids + modified work cases) × 200,000 / Total employee
hours of exposure
d. (Total recordable cases × 200,000) / Total employee hours of exposure
✔️ Correct Answer: A
Rationale:
The Lost Time Frequency Rate (LTFR) is calculated by multiplying the number of lost
time cases by 200,000 and dividing by the total employee hours of exposure. This
standardizes the rate per 100 full-time equivalent workers. Option A is correct. Option B
calculates the Injury Severity Rate (IRS), Option C calculates the Total Recordable
Incident Frequency (TRIF), and Option D is a general recordable rate calculation.
A safety manager is evaluating a company's Health and Safety Management System
(HSMS). Which type of system maintains high standards throughout every part of a
company's organization?
a. Quality Management System (QMS)
b. Health and Safety Management System (HSMS)
c. Environmental Management System (EMS)
d. Incident Management System (IMS)
✔️ Correct Answer: B
Rationale:
A Health and Safety Management System (HSMS) is a complete system that maintains
high standards throughout every part of a company's organization by integrating health
and safety into all operations and decision-making processes. Option B is correct. QMS
focuses on quality, EMS on environmental issues, and IMS on incident response.
A safety professional is calculating the Injury Severity Rate (IRS). Which formula is used
to determine the IRS?
, a. (Lost time cases × 200,000) / Total employee hours of exposure
b. (Lost work days × 200,000) / Total employee hours of exposure
c. (Lost time cases + medical aids + modified work cases) × 200,000 / Total employee
hours of exposure
d. (Total recordable cases × 200,000) / Total employee hours of exposure
✔️ Correct Answer: B
Rationale:
The Injury Severity Rate (IRS) measures the severity of injuries by calculating the number
of lost work days per 200,000 hours of exposure. The formula is (Lost work days ×
200,000) / Total employee hours of exposure. Option B is correct. Option A calculates
LTFR, Option C calculates TRIF, and Option D is a general recordable rate.
On a construction project with multiple employers, who is responsible for developing a
collaborative environmental management program?
a. Each individual subcontractor
b. The prime contractor
c. The government regulatory agency
d. The joint health and safety committee
✔️ Correct Answer: B
Rationale:
The prime contractor has the overall responsibility for developing and coordinating
environmental management programs on a project site with multiple employers. This
ensures consistency and collaboration across all parties. Option B is correct.
Subcontractors implement their parts, but the prime contractor coordinates. Regulatory
agencies enforce but do not develop programs.
A safety manager is developing an Action Plan to improve the Health and Safety
Management System (HSMS). What is the primary purpose of an Action Plan?
a. To document all safety violations
b. To provide a plan to improve the HSMS over the upcoming year
c. To assign blame for incidents
d. To reduce insurance premiums
