WHMIS and Chemical Management

[OHS Regs., s.xx] Follow these links to related legislation.

Highlighted words reveal definitions when selected.

Every workplace has hazardous products - ranging from cleaning products to full chemical production. Taking steps to manage chemicals present at the workplace will reduce health and safety risks, lower environmental impact, and reduce operation costs. If chemicals are not used, stored and handled properly, they can cause injury, illness, disease, fire, explosions, property damage, or harm to the environment. For example, chemical exposure occurs when we breathe them in, absorb them through the skin, or when they are unintentionally swallowed.

The workplace hazardous materials information system (WHMIS) is a standardized system which includes rules for hazard classification, labelling, safety data sheets (SDSs), and worker education and training. It provides workers with important health and safety information about hazardous products in the workplace.

Employer Responsibilities

Employers must:

  • Conduct a risk assessment and develop written rescue and evacuation procedures where employees use, store, or handle hazardous products at a work site and there is a potential need to evacuate or rescue workers. [OHS Regs., s. 38]
  • Establish and maintain a chemical control program that is appropriate for the risks to worker health and safety. [OHS Regs., s. 12(1)(h)] [OHS Regs., s. 42(2)]
  • Eliminate hazardous products in the workplace, or substitute with a less hazardous product, if possible. Where elimination or substitution is not possible, use engineering and administrative controls to make sure that hazardous products are used, stored and handled safely. Consult the SDS or consumer product safety information for advice on suitable controls. [OHS Regs., s. 42(3), (4) and (5)]
  • Make sure hazardous products are used, stored, and handled only when all safety and legislative requirements are satisfied. For hazardous products, WHMIS requirements include labels, identifiers, SDS, and worker education and training. Where WHMIS requirements are not met, an employer is only permitted to store a hazardous product at the workplace while they are actively looking for the required information. [WHMIS Regs., s. 4]
  • Develop policies and procedures to protect a worker from exposure to a reproductive toxin (when pregnant or trying to conceive) or a sensitizer, if applicable. Actions must include informing workers of the hazard, identifying ways to reduce or eliminate exposure, and may include protective reassignment. [OHS Regs., s. 42(10) and (12)]
  • Clean up spills involving solvents, oils, greases, paints and other flammable products with an approved non-combustible absorbent product. Store used absorbents in a covered metal container outside of work areas, until it can be disposed of. [OHS Regs., s. 42(13) and (14)]

Supplier Labels

Employers must:

  • Make sure every hazardous product received at the workplace has a WHMIS label affixed, printed, or attached to it. Where a supplier label is missing, use a workplace label. [WHMIS Regs., s. 7(1)] [WHMIS Regs., s. 7(7)]
  • Affix, print, or attach a label (similar to a supplier label) to an unpackaged hazardous product or hazardous product that is transported as a bulk shipment. [WHMIS Regs., s. 7(8)]
  • Not remove, deface, modify, or alter a supplier label unless it is a small container (three millilitres or less) and the label interferes with normal use. [WHMIS Regs., s. 7(2) and (6)]
  • Update labels or information on the container when significant new data becomes available. [WHMIS Regs., s. 7(4)]
  • Replace labels when they cannot be read (illegible) or have been removed [WHMIS Regs., s. 7(5)].

Workplace Labels

Employers must:

  • Use a workplace label for a hazardous product produced at the workplace, unless the product is about to be labelled for sale. [WHMIS Regs s. 8(1) and (3)]
  • Update workplace labels when new significant data becomes available. [WHMIS Regs., s. 8 (2)]
  • Make sure a workplace label is used when a hazardous product is decanted or transferred to another container unless the container: [WHMIS Regs., s. 9(1)]
    • Will be used exclusively by and be kept under the control of the worker who filled the container;
    • Is used only during the same shift in which it was filled;
    • The content is identified; and
    • The entire amount of the product stored in the container is needed for immediate use. [WHMIS Regs., s. 9(2)]

Laboratory Labels

Employers must:

  • Make sure a hazardous product that meets the definition of a laboratory sample under the regulations has a supplier label that contains: [WHMIS Regs., s. 12(1)]
    • The chemical name (or generic chemical name) of ingredients that are regulated by WHMIS;
    • The statement “Hazardous Laboratory Sample”; and
    • An emergency telephone number that will allow a person to get information required to be disclosed on an SDS, 24 hours a day, 7 days a week.
  • Use a workplace label to identify a hazardous product a container other than the original container received from the supplier, or is produced in the workplace or a laboratory unless: [WHMIS Regs., s. 12(2)]
    • It is laboratory sample;
    • Intended solely for use, analysis, testing, research, development, or evaluation in a laboratory;
    • It is not removed from the laboratory;
    • It is clearly identifiable to workers at the workplace; and
    • Workers are educated and trained about the safe use, storage, handling, and disposal of the hazardous product; and the mode of identification used.
  • Make sure worker education and training allows the worker to easily identify and locate: [WHMIS Regs., s. 12(3)]
    • The information required on the SDS;
    • A label or document that includes the information required on a hazardous product a container other than the original container, or is produced in the workplace or a laboratory; and
    • Other information necessary to ensure the safe use, storage, handling, and disposal of the laboratory sample.
  • Make sure that a copy of a supplier or employer SDS is available to workers. [WHMIS Regs., s. 13(7) and (8)]

Safety Data Sheets

Employers must:

  • Make sure every hazardous product received at the workplace has a SDS that complies with the Canadian WHMIS regulatory requirements. [WHMIS Regs., s. 13(1)]
  • Where possible, obtain an updated SDS when the revision date on the SDS is three or more years old. [WHMIS Regs., s. 13(2)] An updated SDS is not required if the new SDS does not apply to the original product, or if there is written confirmation from the supplier that the SDS has not changed. [WHMIS Regs., s. 13(3)]
  • Add any significant new data to the existing SDS, if an updated SDS is not available. [WHMIS Regs., s. 13(4)]
  • Make sure that all hazardous products produced at the workplace have a SDS, and that the SDS is updated as soon as practical and not later than 90 days after new significant data becomes available. [WHMIS Regs., s. 14]
  • Make SDSs readily available to workers who may be exposed to a hazardous product, and to the OHS Committee or Worker Health and Safety Representative. [WHMIS Regs., s. 15(a) and (b)]
  • Consult with the OHS Committee or Worker Health and Safety Representative on how to best make the SDSs readily available [WHMIS Regs., s. 15(c)]
  • Employers may provide workers with an SDS that is in a different format from the supplier SDS, as long as the required information is disclosed, the new format is approved by the OHS Committee or Worker Health and Safety Representative, and the new format SDS indicates that the supplier SDS is available at the workplace. [WHMIS Regs., s. 13(5)]
  • Notify workers who may be exposed to a hazardous product and the OHS Committee or Worker Health and Safety Representative when significant new data becomes available. [WHMIS Regs., s. 16]
  • Where a hazardous product is made at a workplace, disclose necessary information to an OHS Officer, worker, OHS Committee or Worker Health and Safety Representative relating to the sources of the toxicological data used to create the employer’s SDS. [WHMIS Regs., s. 25]

These Regulations also provide a mechanism for maintaining confidential business information by registering a hazardous product with Health Canada under the Hazardous Materials Information Review Act. However, even with approval by this Act, confidential business information must be provided to a healthcare professional treating a person in an emergency. The health professional must keep this information confidential at the employer’s request. [WHMIS Regs., s. 23] [WHMIS Regs., s. 17...22] [WHMIS Regs., s. 24]
