What does Occupational Health and Safety Act say with regards to employer’s duties?

Before we delve deeper into fall protection training, this is a good starting point. In fact, Sec 25 of the Occupational Health and Safety Act sets out general and specific duties for an employer.

General duties:

The employer has the key general duties to:

  • Take all reasonable precautions for protecting workers’ health and safety
  • Ensure that the company maintains all equipment, material, and protective equipment in good condition
  • Provide workers with information, instruction, and supervision for protecting their health and safety
  • Cooperate with the Joint Health and Safety Committee

Specific duties:

The employer has the key specific duties to:
  • Comply with all the regulations made under the Occupational Health and Safety Act
  • Develop and implement an OHS program and policies
  • Provide Joint Health and Safety Committee with health and safety reports

Moreover, sub-section 1 of sec 23 of the OHS Act lists out the duties of a constructor.

Duties of a constructor:

The constructor has the duties to:
  • Ensure the company complies with all the measures and procedures prescribed by the OHS Act and its regulations
  • Make sure every employer and worker engaged in a construction project complies with the Act’s regulations and requirements

Working At Heights as a mandatory requirement in Ontario

What does the OHS Act say?

The Occupational Health and Safety Awareness and Training Regulation (Ontario Regulation 297/13) under the OHS Act clearly sets out WAH as a mandatory requirement.

Moreover, the regulation clearly specifies the training requirements for the working at heights program. Furthermore, the training will have a validity period of three years from the date of completion. Also, a participant needs to complete this training only through a CPO-approved training provider.

Employers have to ensure workers use fall protection

Under construction projects, sub-section 26.2 (1) of O. Reg. 213/91states that:

  • Employers will continue to have a duty to ensure that their workers who may use a fall protection system are trained properly
  • Moreover, the training can be through oral and written instructions provided by a competent person

Furthermore, please note that the Occupational Health and Safety Act defines a workplace as any land, premises, location or thing at, upon, in, or near which a worker works.

Therefore, the Occupational Health and Safety Act considers a construction site as the workplace for construction workers. Hence, employers should follow the construction regulations falling under the Act. Further, the regulations clearly state that working at heights is a mandatory requirement in Ontario.
