IHSA Risk Analysis & Hazard Identification 5

Question 1

Under the Canadian Occupational Health and Safety framework, the 'Internal Responsibility System (IRS)' requires that hazard identification is:

Accepted Answer

A shared responsibility among employers, supervisors, and workers at all levels

Answer

The IRS holds every workplace party — employer, supervisor, and worker — jointly responsible for identifying and controlling hazards.

Question 2

A 'critical incident stress' following a workplace fatality can affect risk perception by:

Accepted Answer

Causing workers to underestimate future risks once initial shock fades

Answer

After initial heightened awareness fades, workers may revert to or exceed prior risk normalization, a phenomenon known as risk habituation.

Question 3

Which factor most increases the likelihood that a hazard will cause an incident?

Accepted Answer

Workers are routinely exposed to the hazard without adequate controls

Answer

Routine, uncontrolled exposure to a hazard significantly raises the probability of it causing harm.

Question 4

A 'management of change (MOC)' process is triggered in infrastructure projects to:

Accepted Answer

Systematically evaluate hazards introduced by modifications to equipment, processes, or procedures

Answer

MOC ensures that any planned change is reviewed for new or increased hazards before implementation, preventing unintended consequences.

Question 5

In the context of IHSA coaching, 'safety climate' most directly influences hazard identification by affecting:

Accepted Answer

Workers' willingness to report hazards without fear of reprisal

Answer

A positive safety climate where reporting is encouraged and blame-free leads to more hazards being identified and corrected before incidents occur.
