As of September 17, 2021, both of these regulations are not available online.
The Workplace Safety and Health (First-Aid) Regulations, 2021
These regulations provide that every workplace must be equipped with a sufficient number of first aid boxes and maintain them properly. Workplaces that have 25 or more persons or that handle machinery, equipment and hazardous substances as specified in the Workplace Safety and Health Order, must designate one first-aider who has finished training of first-aid treatment out of every 50 employees. In addition, workplaces with more than 100 employees are required to have a first-aid room, and they are to be provided appropriate facilities for emergency treatment where there is a possibility of exposure to toxic and corrosive substances.
Workplace Safety and Health (General Provisions) (Amendment) Regulations, 2021
These regulations partially revised “Workplace Safety and Health (General Provisions) Regulations, 2014”. Occupiers of workplaces must ensure that one or more warning labels are attached to the containers/packaging of hazardous substances and must make the SDS available to all persons who may be exposed to those substances. These regulations also require the sellers or agents of hazardous substances to provide the buyer with a SDS which contains accurate and sufficient information about the substance. In addition, fall prevention measures are strengthened. Occupiers of workplaces must ensure that all openings in floors of the workplace are covered by fences or other means, except where covers or fences cannot be installed for operational reasons.
