Q1. Which type of system is described as a complete system that maintains high
standards throughout every part of a company's organization? [Multiple Choice]
A) Health and Safety Management System HSMS
1
, B) Action Plan
C) Project Safety Plan
D) SECOR
Answer: Health and Safety Management System HSMS
Explanation: A Health and Safety Management System (HSMS) is an organization-wide system
designed to keep standards high across all parts of a company. A Project Safety Plan is the
guiding document for employers on a specific site, not the company-wide system. An Action Plan
is a yearly plan to improve the HSMS, not the overall system itself. SECOR is an evaluation
program for small employers; it is not the system that maintains standards.
Q2. Communication is the expression or exchange of which four things? [Multiple
Choice]
A) Words, Sounds, Signs, Visuals
B) Tell, Show, Do, Review
C) Information, Ideas, Thoughts, Feelings
D) Plan, Organize, Lead, Control
Answer: Information, Ideas, Thoughts, Feelings
Explanation: Communication is defined here as exchanging information, ideas, thoughts, and
feelings — the content of communication. 'Words, Sounds, Signs, Visuals' are the channels or
methods individuals use to communicate, not the content itself. 'Tell, Show, Do, Review' are
instructional steps for OJT, and 'Plan, Organize, Lead, Control' are management functions.
Q3. According to the material, what are the two main types of hazards? [Multiple
Choice]
A) Plan & Organize
B) Words & Sounds
C) Health & Safety
D) Formal & Site-specific
Answer: Health & Safety
Explanation: The source distinguishes hazards by type as health hazards and safety hazards —
together 'Health & Safety'. 'Formal & Site-specific' are two types of hazard-assessment
processes, not hazard types. 'Plan & Organize' are management tasks for leading an HSMS, and
'Words & Sounds' are means people use to communicate; neither pair describes hazard types.

,Q4. Which three rights make up the workers' basic rights in Canada as listed in
the material? [Multiple Choice]
A) Plan, Organize, Lead
B) Tell, Show, Do
C) Right to Know, Right to Participate, Right to Refuse
D) Words, Sounds, Signs
Answer: Right to Know, Right to Participate, Right to Refuse
Explanation: The three basic workers' rights are the right to know (about hazards), the right to
participate (in safety processes), and the right to refuse unsafe work. 'Plan, Organize, Lead' are
management duties. 'Tell, Show, Do' are steps in OJT instruction. 'Words, Sounds, Signs' are
modes of communication. None of those are the workers' legal rights.
Q5. Explain how the steps 'verifying understanding' and 'reflecting' complete the
effective communication process and why each is important. [Short Answer]
Answer: Verifying understanding confirms the receiver interpreted the message as
intended, closing the feedback loop and allowing correction if needed; reflecting lets
participants consider what worked and why, so future messages can be improved.
Together they ensure accurate exchange and continual improvement of communication.
Explanation: A complete answer shows that verifying understanding is about checking the
receiver’s interpretation (so misunderstandings can be caught) and that reflecting is about
learning from the interaction to improve future communication. This explains the roles of
feedback and review in making the communication process effective rather than merely listing
steps.
Q6. Which description matches a safety hazard as defined in the source
material? [Multiple Choice]
A) Has the potential to cause immediate injury or damage
B) Absolute Losses
C) Has the potential to cause an acute or chronic condition, illness, or disease
D) Lost Time Frequency Rate (LTFR)
Answer: Has the potential to cause immediate injury or damage
Explanation: A safety hazard is one that can cause immediate injury or physical damage — it is
about acute events. 'Has the potential to cause an acute or chronic condition, illness, or disease'
describes a health hazard. 'Lost Time Frequency Rate (LTFR)' is an incident-rate metric, not a
3
, hazard description. 'Absolute Losses' refers to costs associated with loss-type incidents and is not
a hazard type.
Q7. Which formula correctly calculates the Lost Time Frequency Rate (LTFR)?
[Multiple Choice]
A) (lost time cases + medical aids + modified work cases) x 200,000 / Total employee
hours of exposure.
B) (Lost work days x 200,000) / Total employee hours of exposure.
C) (Lost time cases x 200,000) / Total Employee Hours of Exposure.
D) Absolute Losses
Answer: (Lost time cases x 200,000) / Total Employee Hours of Exposure.
Explanation: LTFR uses the count of lost time cases scaled per exposure hours: (Lost time cases ×
200,000) divided by total employee hours of exposure. The '(Lost work days × 200,000)...' formula
is the injury severity rate (it uses days, not cases). The combined-case formula with medical aids
and modified work cases is the TRIF calculation, not LTFR. 'Absolute Losses' is a type of cost
classification and not a frequency-rate formula.
Q8. Explain the significance of the final step, 'Repeat the process if there is a
change in condition,' in the five-step site-specific hazard assessment model. [Short
Answer]
Answer: Repeating the process when conditions change ensures that tasks, hazards, and
controls are re-evaluated so previously identified controls remain effective and new
hazards are addressed. It makes the assessment a continuous, adaptive cycle that
maintains safety as conditions evolve.
Explanation: A strong answer links the repeat step to the need for ongoing reassessment:
hazards and controls can change with conditions, so re-running the five steps keeps protections
current. This teaches why the model is iterative rather than a one-time checklist.
Q9. Which description matches a health hazard as defined in the source
material? [Multiple Choice]
A) Has the potential to cause an acute or chronic condition, illness, or disease
B) Has the potential to cause immediate injury or damage
C) Absolute Losses
D) Anyone responsible for product during its lifecycle
Answer: Has the potential to cause an acute or chronic condition, illness, or disease
