That is not an express requirement of OHS Regulations in Saskatchewan or, to my knowledge, in any other province. However, keep in mind that the OHS regulations aren’t the primary source of requirements governing fire alarms in workplaces. In fact, the OHS regulations get into these issues in only a general way. It’s also imperative to check the requirements of fire codes, starting with the National Fire Code of Canada, 2020. Provincial and municipal fire and building codes may also apply. These laws provide the nuts and bolts details on fire alarms and equipment. Hope this helps. Glenn Demby, Editor In Chief, OHS Insider
