The positive tree provides a graphical representation of how a job should not be done.

Which of the following is NOT a general lifting guideline?

keep lower body straight

Which of the following is an example of a repetitive strain injury?

Raynaud's syndrome

The performing arts (theatre, dance, music) do not always come to mind when hazardous workplaces are being discussed. 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. Under what legislation could the theatre be liable for failing to maintain the stage in a better condition?

Canada Labour Code

A hazard is any activity that may occur on a day-to-day basis as a direct or indirect result of some human or human-related undertaking.

False

At the winery, part of Alain's job involves being lowered through a narrow opening into a giant tank to clean it 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.

Fault tree

In order to accurately describe the risks involved in using various types of lasers by surgeons at the clinic, Oleg must consider both likelihood and severity of both overt traumatic and overexertion injuries.

True

Jeremy works in a large shipping area of a courier company. A guard placed around the perimeter of a conveyor is an example of an engineering control.

True

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.

True

Working in an awkward position is an example of an overexertion injury.

True

Which of the following most closely reflects the definition of a hazard, as given in the textbook?
