Study Notes
WHMIS and GHS
- WHMIS (Workplace Hazardous Materials Information System) is a Canadian federal legislation that aims to protect employee health and safety by identifying and addressing risks associated with hazardous materials.
- GHS (Globally Harmonized System of Classification and Labelling of Chemicals) is an internationally recognized system that defines and classifies the hazards of chemical products and communicates health and safety information on labels and safety data sheets.
Key Components of GHS
- Hazard identification
- Product classification
- Labelling
- Safety data sheets
- Worker education and training
Controlled and Non-Controlled Products
- Controlled products are substances that can be classified into one or more of the nine GHS hazard classes.
- Non-controlled products include radioactive materials, domestic products, cosmetics, food, and drug additives.
GHS Pictograms
- Hazard pictograms form part of the GHS and are used to convey specific information on labels and safety data sheets.
- There are two sets of pictograms: one for labelling containers and workplace hazard warnings, and another for transporting dangerous goods.
- Three categories of labels:
- Physical Hazards
- Health Hazards
- Environmental Hazards
GHS Hazard Pictograms
- Physical Hazards:
- Explosives
- Flammable
- Oxidizers
- Compressed gases
- Corrosive materials
- Health Hazards:
- Toxic substances
- Chronic health issues
- Skin and respiratory sensitization or carcinogenicity
- Environmental Hazards:
- Acute and chronic hazards to the aquatic environment
Duties and Responsibilities
- The Supplier:
- Responsible for classifying controlled products
- Ensuring required tests are carried out on controlled products
- The Employer:
- Ensuring employees are instructed on safety data sheets and their significance
- The Worker:
- Not responsible for producing safety data sheets, but plays a role in providing information on safety data sheets at the job site
WHMIS Labels and GHS
- A GHS label is a source of information about a controlled product, attached to the product or its container.
- Labels can take various forms (mark, sign, seal, stamp, device, tag, or wrapper).
- Supplier labels must be written in English and French.
- Workplace labels are required when a hazardous chemical is transferred to a secondary container for more than one day or if multiple individuals will have access to it.
Safety Data Sheets (SDS)
- 16 sections of information:
- Identification
- Hazard pictograms
- Composition/ingredients
- First aid measures
- Firefighting measures
- Accidental release measures
- Handling and storage
- Exposure controls (PPE)
- Physical and chemical properties
- Stability
- Toxicology
- Ecological information
- Disposal
- Transport information
- Regulatory information
- Other information
