Did you know subcontractors are required to report any hazards that may affect their company or other companies on site?

Employing contractors to work for you is a common practice, but are you clear on your responsibilities regarding their health and safety? What if you are the subcontractor, are you clear on your responsibilities? Whether you are a general contractor or subcontractor working at a project or workplace in Nova Scotia you have legal duties and requirements prescribed under the Occupational Health and Safety Act and Regulations to ensure work is performed in a safe and healthy manner. Employers should document, in writing, how they are complying with or exceeding regulations in relation to their general contractors or subcontractors. This documentation will give the employer a history of how the company's occupational health and safety program has progressed over time. Second, it will provide up-to-date documentation that can be used as a defense to charges in case an incident occurs despite an employer's efforts.

A duty imposed by the Act and Regulations on an employer, is also imposed on any contractor, constructor, supplier, employee (including a dependent contractor), owner, or self-employed person, to the extent of their authority and ability to discharge the duty in the circumstances.

Risks of not fulfilling these duties and responsibilities include:

  • Injury or death
  • Property damage
  • Financial impacts, such as from downtime, fines, breach of contract, and loss of business
  • Conviction under the OHS Act and/or regulations
  • Conviction under the Criminal Code

Internal Responsibility System

The Internal Responsibility System (IRS) is the foundation of the OHS Act. Everyone at a project or workplace who can affect the health and safety of persons there, shares responsibility for protecting themselves and others. Everyone must work together to create and maintain a safe and healthy workplace by taking every precaution that is reasonably practicable under the circumstances, to the extent of their authority and ability to do so. The IRS includes a framework for four basic worker rights: the right to Know, the right to Participate, the right to Refuse unsafe work, and the right to Grieve/Complain. The Occupational Health and Safety Division of the Department of Labour and Advanced Education supplements the IRS by establishing and clarifying responsibilities under the law, supporting persons in carrying out their responsibilities, and intervening appropriately when those responsibilities are not met.

The extent of Duties and Requirements

At a project or workplace where there are multiple persons with prescribed health and safety duties and requirements, it is important to determine who has the greatest degree of control over these matters. This person bears primary responsibility for complying with the duties and requirements prescribed in the Act and Regulations.

The person with the greatest authority and ability to ensure that a duty is discharged or a requirement is met, is presumed to be the person with the greatest degree of control. This includes an owner, where a lease or other property right agreement is prima facie evidence that they have the greatest degree of control over that land or premises.

Where the person with the greatest degree of control complies as prescribed; the person(s) with lesser control are relieved of the obligation, with these provisions only:

  • for the time during which the person with the greatest degree of control complies;
  • where simultaneous compliance would result in unnecessary duplication of effort and expense; and
  • where the health and safety of persons at the workplace is not put at risk by compliance by only one person.

Where the person with the greatest degree of control fails to comply as prescribed; the person(s) with lesser control shall comply with the provision, where possible. In that case, the remaining person(s) with lesser control is relieved of the obligations, with the same provisions as above.

Take note that a specific duty or requirement, such as those listed below, does not limit the generality of any other duty or requirement imposed by the Act or the regulations.

Specific Duties and Requirements

  • At a project, take every precaution that is reasonable in the circumstances to ensure:
