,Q1. A construction contractor proposes to use a silica-generating process on a site.
Under Alberta OHS legislation, which combination of controls must be implemented
to achieve the highest level of worker protection?
A. Substitute with a non-silica abrasive, then use local exhaust ventilation and
respiratory protection as backup
B. Provide respirators as the primary control, supplemented by administrative controls
like job rotation
C. Implement wet methods, then conduct air monitoring and require medical
surveillance
D. Use water suppression alone, as it eliminates the hazard entirely
Correct Answer: A. Substitute with a non-silica abrasive, then use local exhaust
ventilation and respiratory protection as backup
Rationale: The hierarchy of controls mandates elimination/substitution first, followed by
engineering controls, then administrative controls, and finally PPE. Option A correctly
sequences substitution, engineering (ventilation), and PPE as backup. Options B, C, and D
either prioritize PPE or fail to address the hierarchy properly.
Why Wrong:
B - PPE is the least effective control and should not be primary when higher-order
controls are feasible.
C - Wet methods and monitoring are engineering/admin controls, but they do not
include substitution, which is higher in the hierarchy.
D - Water suppression reduces but does not eliminate the hazard; it must be used with
other controls.

Chemical Hazards, Silica.
Q2. During a worksite audit, you observe a worker operating a forklift without a
seatbelt. According to the Alberta OHS Code, which of the following is the employer's
primary obligation?
A. Immediately discipline the worker to deter future non-compliance
B. Ensure the worker uses the seatbelt and take measures to prevent recurrence
C. Retrain the worker on forklift operation and document it
D. Report the incident to OHS within 24 hours
Correct Answer: B. Ensure the worker uses the seatbelt and take measures to prevent
recurrence
Rationale: Employers must ensure workers use required protective equipment and take
corrective action. Discipline alone (A) is not sufficient; retraining (C) is part of but not the
primary obligation; reporting (D) is only for serious incidents.
Page 3
, Why Wrong:
A - Discipline is not the primary obligation; ensuring compliance and prevention is.
C - Retraining is a component but does not address immediate enforcement of safety
equipment use.
D - Reporting is required only for serious injuries or incidents, not minor
non-compliance.
Reference: Government of Alberta. (2023). Occupational Health and Safety Act, Section
2(1) and OHS Code Part 18.
Q3. A safety officer is investigating a fall from a ladder that resulted in a serious
injury. Which sequence of steps best follows the incident investigation process?
A. Secure the scene, gather evidence, interview witnesses, analyze root causes, write
report, implement corrective actions
B. Interview witnesses first, then secure the scene, analyze data, write report,
implement corrective actions
C. Analyze root causes, then gather evidence, interview witnesses, write report,
implement corrective actions
D. Write report immediately, then secure the scene, interview witnesses, analyze root
causes, implement corrective actions
Correct Answer: A. Secure the scene, gather evidence, interview witnesses, analyze
root causes, write report, implement corrective actions
Rationale: Proper investigation requires securing the scene to preserve evidence, then
systematic data collection (evidence, interviews), analysis, reporting, and corrective
actions. Options B, C, D misorder steps, risking evidence loss or premature conclusions.
Why Wrong:
B - Interviews before securing the scene can compromise evidence and lead to biased
information.
C - Analysis before evidence collection is premature and unsupported.
D - Writing the report before investigation is illogical and unprofessional.

Materials.
Q4. According to Alberta OHS regulations, which of the following situations requires
the employer to conduct a formal hazard assessment?
A. Before any work begins at a new site, and whenever there is a change in work
conditions
B. Only when a worker reports a hazard
C. Annually, regardless of changes
D. Only after an incident occurs
