What Alberta requires
- An employer assesses a work site and identifies existing and potential hazards before work begins, prepares a report of the results and the methods used to control or eliminate the hazards, records the date it was prepared or revised, and repeats it at reasonably practicable intervals, when a work process is introduced or changes, and before significant additions or alterations to the siteOccupational Health and Safety Code, Alta Reg 191/2021, s. 7
- The employer involves affected workers in the hazard assessment and in eliminating or controlling the hazards identified; a hazard is eliminated where reasonably practicable, otherwise controlled, using engineering controls first where reasonably practicableOccupational Health and Safety Code, ss. 8 (1), 9 (1), (2)
- An employer that regularly employs 20 or more workers establishes a joint health and safety committee, whose duties include dealing with workers' health and safety concerns, taking part in the employer's hazard assessment, making recommendations, and reviewing the employer's work site inspection documentationOccupational Health and Safety Act, SA 2020, c. O-2.2, s. 13 (1), (6)
- An employer that regularly employs 5 to 19 workers designates a worker who is not part of management as the health and safety representative, who carries out the same duties as a committee with a representative of the employerOccupational Health and Safety Act, s. 14 (1), (4)
- An employer that regularly employs 20 or more workers, or is directed to by a Director, establishes and implements a health and safety program subject to the OHS CodeOccupational Health and Safety Act, s. 16
- When a worker refuses dangerous work and the employer does not remedy the alleged undue hazard immediately, the employer, after talking with the worker, immediately inspects it, takes any action needed to remedy it, prepares a written report of the refusal, the inspection and the action taken, and gives the worker a copyOccupational Health and Safety Act, s. 17 (8), (9), (11), (12)
The hazard assessment comes first
Before work begins, the employer assesses the work site for existing and potential hazards and writes up the results and the controls, with the date. The assessment is repeated at reasonable intervals, when a work process is introduced or changes, and before significant changes to the site. Affected workers take part, and hazards are eliminated where possible, otherwise controlled, engineering controls first. An inspection checks that the assessment is current and its controls are actually in place.
Committees, representatives and programs
Employers with 20 or more workers have a joint health and safety committee and a health and safety program. Employers with 5 to 19 workers designate a non-management worker as health and safety representative. Either one takes part in hazard assessments, deals with workers' concerns, makes recommendations and reviews the employer's work site inspection documentation, so inspection reports need to be kept where they can see them.
When a worker refuses dangerous work
If a worker refuses work they believe is an undue hazard and it is not fixed right away, the employer inspects it immediately after talking with the worker, fixes what needs fixing, writes a report of the refusal, the inspection and the action taken, and gives the worker a copy.
Common mistakes
- Inspecting against a hazard assessment written for different work.
- Doing the hazard assessment without the workers who do the job.
- Keeping inspection reports where the committee or representative cannot review them.
- No written report after inspecting a work refusal.
- Relying on gloves and glasses where an engineering control was practicable.
