The Workplace Hazardous Materials Information System (WHMIS) is a comprehensive system for providing health and safety information on hazardous products intended for use, handling, or storage in Canadian workplaces. The main components of WHMIS are hazard identification and product classification, labelling, safety data sheets, and worker education and training.

WHMIS

For products that fall under the Workplace Hazardous Materials Information System (WHMIS) regulations, the regulation covers all hazardous products that are used, handled, stored, or produced in the workplace. [WHMIS Reg. S. 2(1)] Hazardous products may not be used, handled, stored, or produced until all of the requirements of the regulations are followed, including labels or identifiers, safety data sheets, and worker education and training. [WHMIS Reg. S. 3]

Employers must inform all workers who work with or may be exposed to a hazardous product about the information received from the supplier, and any other information about the hazards of that product. [WHMIS Reg. S. 4] The education and training is to be developed and implemented at the workplace, in consultation with the committee or representative. [WHMIS Reg. S. 5(3)] This education and training must result in the worker being able to apply these skills to protect their health and safety. [WHMIS Reg. S. 5(4)] The information required includes: [WHMIS Reg. S. 5(2)]

  • content on a supplier label and workplace label, and the significance of that information;
  • content on a safety data sheet (SDS), and the significance of that information;
  • procedures for safe use, handling, storage, and disposal of the hazardous product;
  • procedures to follow when emissions are present; and
  • procedures to follow in an emergency.

Evaluation of the education or training may be done using written tests, practical demonstrations, or other suitable methods. [WHMIS Reg. S. 5(4)] A review of the education and training is required at least annually, or more frequently if there is a change in the work conditions or the information about the hazard. [WHMIS Reg. S. 5(5)]

Labels

Employers must make sure that:

  • all hazardous products or containers received at the workplace has the supplier affixed, printed, or attached to it; [WHMIS Reg. S. 6(1)]
  • the supplier label is not be removed, defaced, modified or altered [WHMIS Reg. S. 6(2)] except when the label is meant to be removed under normal use and is 3 ml or smaller; [WHMIS Reg. S. 6(4)]
  • if the label becomes unreadable (illegible) or is removed, the employer must replace with either a supplier or workplace label; [WHMIS Reg. S. 6(3)]
  • if the supplier provides significant new data, that the label is updated; and [WHMIS Reg. S. 6(5)]
  • if a product is received without a supplier label, that a workplace label is attached before it is used.

Workplace labels must state a product identifier (that is identical to the SDS), contain the information for safety handling, and state that a SDS, if supplied or produced, is available. [WHMIS Reg. S. 7(1)] Workplace labels must also be updated when significant new data is available. [WHMIS Reg. S. 7(2)] Workplace labels are also required when the hazardous product is produced in the workplace [WHMIS Reg. S. 8(1)], and on decanted products. [WHMIS Reg. S. 9(1)]

Alternate methods for labelling include using a colour code, label, placard, or other methods when the hazardous product is contained or transferred through a pipe, piping system, process vessel, reaction vessel, tank car, tank truck, ore care, conveyer belt, or similar. [WHMIS Reg. S. 10] Placarding may be used if the hazardous product is not in an container, in a container intended for export, or a container for sail or distribution that is otherwise labelled appropriately. Placards must show the information normally required on a workplace label, and be clearly placed and readable to workers. [WHMIS Reg. S. 11]

Safety Data Sheets (SDSs)

Employers must obtain (from the supplier) a safety data sheet for each hazardous product used, handled or stored at the workplace. [WHMIS Reg. S. 13(1)] SDSs must be available to each worker who works with a hazardous product or who may be exposed to it, and to the committee or representative. The employer can work with the committee or representative to best determine how to make the SDSs available. [WHMIS Reg. S. 16] SDSs may be provided in a format different than the SDS as long as there is no less content, and the employer’s sheets state that an SDS is available. [WHMIS Reg. S. 13(4)]

The employer must update the SDS with any significant new data about the hazardous product as soon as reasonably practicable after the data or information is provided by the supplier or the employer otherwise determines. [WHMIS Reg. S. 13(3)]

When a hazardous product is produced at the workplace, the employer must prepare an SDS for that product according to the Hazardous Products Regulations, and keep the SDS updated not later than 90 days after significant new information becomes available to the employer. [WHMIS Reg. S. 14] The toxicological data used to prepare the SDS must be made available to an officer, a worker, committee or representative on request. [WHMIS Reg. S. 15]

Laboratory samples

When an employer receives a laboratory sample, the label must:

  • display the chemical name or generic chemical name (if known) that is present individually or in a mixture; and
  • contain the statement "Hazardous Laboratory Sample. For hazard information or in an emergency, call/ Échantillon pour laboratoire de produit dangereux. Pour obtenir des renseignements sur les dangers ou en cas d’urgence, composez", and have an emergency telephone number.

Certain labelling requirements do not apply if the hazardous product is a laboratory sample or produced in the laboratory, it is intended solely for use, analysis, testing or evaluation in a laboratory or for testing for research and development, and is clearly identified. Workers must be educated and trained in the safe use, handling and storage of the hazardous product. [WHMIS Reg. S. 12(3) and 12(4)]

"hazardous product" means any product, mixture, material or substance that is classified in accordance with the regulations made under subsection 15(1) of the Hazardous Products Act (Canada) in a category or subcategory of a hazard class listed in Schedule 2 of that Act. These regulations do not apply where the hazardous product is: (a) wood or a product made of wood; (b) tobacco or a tobacco product as defined in section 2 of the Tobacco Act (Canada); (c) a manufactured article; or (d) a product being transported or handled pursuant to the requirements of the Transportation of Dangerous Goods Act, 1992 (Canada). These regulations also do not apply to hazardous waste but the employer must make sure that the waste is safely stored and handled through a combination of clear identification and worker education and training.
An employer may store a hazardous product at a workplace while actively seeking information required by these regulations about the hazardous product.
Some products are exempt, including: 2. (2) The provisions of these regulations in respect of supplier labels and safety data sheets do not apply where the hazardous product is (a) an explosive as defined in section 2 of the Explosives Act applicable (Canada); (b) a cosmetic, device, drug or food as defined in section 2 of the Food and Drugs Act (Canada); (c) a pest control product as defined in subsection 2(1) of the Pest Control Products Act (Canada);
Procedures are also required for safe use, handling, storage and disposal when the hazardous product is contained or transferred in: (i) a pipe or a piping system including valves, (ii) a process vessel or reaction vessel, or (iii) a tank car, tank truck, ore car, conveyer belt or similar conveyance.
This review is done by the employer, in consultation with the committee or representative.
"significant new data" means new data regarding the hazard presented by a hazardous product that (i) changes its classification in a category or subcategory of a hazard class, (ii) results in its classification in another hazard class, or (iii) changes the ways to protect against the hazard presented by the hazardous product.
Workplace labels are not required on portable containers if all of the hazardous product will be used immediately, or if the container will be under the control of that worker only, and only used for that shift.
