Question 23

Kim Sung is a member of the Joint Health and Safety Committee at her workplace and she has been asked to work with an outside safety expert to identify hazards from poor housekeeping throughout the hospital. A walk-through survey would be an effective way for them to collect this data.

Question 24

Question 25

As part of hazard identification, Ray was asked to describe how much time he spent on various tasks and to rank the importance of each of these tasks. This information was necessary for safety sampling.

Question 26

Read the scenario and answer questions. However, performers at Canada's famed Shaw and Stratford festivals encounter many hazards and OH&S incidents can occur. Imagine a theatre with suspended overhead lights, trapdoors in the stage, on-stage sets that look real but are built of flimsy materials, narrow hallways and stairs, and actors engaged in fight scenes using realistic weapons. The same process of hazard recognition, risk assessment, and control must take place.

A) equipment hazard
B) environment hazard
C) materials hazard
D) process hazard

Question 28

At the winery, part of Alain's job involves being lowered through a narrow opening into a giant tank to clean them out in between batches. The first step in the plan should be to vent the container and test the air quality to ensure all vapours have been removed.

Question 29

Read the scenario and answer questions. However, performers at Canada's famed Shaw and Stratford festivals encounter many hazards and OH&S incidents can occur. Imagine a theatre with suspended overhead lights, trapdoors in the stage, on-stage sets that look real but are built of flimsy materials, narrow hallways and stairs, and actors engaged in fight scenes using realistic weapons.
