WHMIS (Workplace Hazardous Materials Information System) worker education and training, along with proper labeling, are critical components of workplace safety. They ensure that workers understand the hazards associated with hazardous materials, know how to handle them safely, and can identify them quickly through standardized labeling. WHMIS education empowers workers to make informed safety decisions and respond appropriately in case of exposure or emergency.

WHMIS Worker Education and Training

  1. Purpose of WHMIS Training:
    • Understanding Hazards: WHMIS training educates workers about the physical and health hazards associated with hazardous materials.
    • Safe Handling Procedures: Workers learn how to safely store, handle, and dispose of hazardous materials, reducing risks to health and safety.
    • Emergency Response: Training covers procedures for responding to spills, leaks, fires, and exposure incidents involving hazardous substances.
  2. Key Components of WHMIS Education:
    • Hazard Identification: Workers learn to recognize WHMIS symbols, classes, and pictograms, which indicate the type of hazards a material presents (e.g., flammable, corrosive, toxic).
    • Safety Data Sheets (SDS): WHMIS training includes how to read and interpret SDSs, which provide essential information about each hazardous product’s properties, risks, and first-aid measures.
    • Label Recognition: Training covers the different types of WHMIS labels (supplier and workplace labels) and the information each must contain.
    • Personal Protective Equipment (PPE): Workers are trained on selecting and using PPE specific to each hazardous material, such as gloves, respirators, and eye protection.
  3. Employer Responsibilities:
    • Provide Initial Training: Employers must provide WHMIS training when workers are first assigned tasks involving hazardous materials.
    • Refresher Training: Periodic refresher training is essential to keep workers updated on safety procedures and any new hazardous materials.
    • Site-Specific Information: Employers should include site-specific hazards, handling procedures, and emergency protocols relevant to the materials used in their workplace.
  4. Worker Responsibilities:
    • Participate in Training: Workers are responsible for attending WHMIS training sessions and understanding the information presented.
    • Apply Safe Practices: Workers must follow safe handling, storage, and disposal procedures for hazardous materials.
    • Report Hazards: Workers should report any spills, leaks, or improperly labeled containers to their supervisor immediately.
  5. Documentation of Training:
    • Training Records: Employers should maintain records of all WHMIS training sessions, including participant names, training dates, and content covered.
    • Evaluation and Assessment: Post-training assessments can help gauge workers’ understanding and retention of WHMIS information.

WHMIS Labels

WHMIS labels are a critical component for identifying hazardous products and informing workers of necessary precautions. Labels are divided into two main types: supplier labels and workplace labels.

  1. Supplier Labels:
    • Definition: Supplier labels are provided by the manufacturer, importer, or distributor of a hazardous product and must meet WHMIS standards.
    • Information Included:
      • Product Identifier: The name of the hazardous product.
      • Pictograms: Symbols that visually indicate the type of hazard, such as flames for flammable products or a skull and crossbones for toxic materials.
      • Signal Word: Either “Danger” or “Warning” to indicate the severity of the hazard.
      • Hazard Statements: Describes the nature of the hazard, such as “May cause respiratory irritation” or “Flammable gas.”
      • Precautionary Statements: Instructions on safe handling, storage, and emergency measures.
      • Supplier Identification: The name, address, and contact information of the supplier.
    • Purpose: Supplier labels provide workers with quick, essential information to recognize hazards and understand safe handling practices before using the product.
  2. Workplace Labels:
    • Definition: Workplace labels are required when a hazardous material is transferred from its original container to a new container or when the original supplier label is missing or illegible.
    • Information Required:
      • Product Identifier: Name of the product.
      • Safe Handling Information: Details on safe handling, use, and precautions.
      • Reference to SDS: An indication that an SDS is available for the product, providing detailed safety information.
    • When to Use:
      • When transferring a product to another container.
      • If the supplier label becomes unreadable or damaged.
      • When a product is produced on-site for internal use and is not covered by a supplier label.
    • Purpose: Workplace labels ensure that all containers in use are labeled with sufficient information to keep workers safe, even if the product has been repackaged or relabeled.
  3. Pictograms:
    • Description: WHMIS pictograms are standardized symbols that visually represent hazards and are part of both supplier and workplace labels.
    • Common Pictograms:
      • Flame: Indicates flammable or combustible hazards.
      • Corrosion: Identifies corrosive substances that can damage skin or metals.
      • Health Hazard: Indicates respiratory sensitizers, carcinogens, or substances that cause organ damage.
      • Skull and Crossbones: Represents acute toxicity.
      • Exclamation Mark: Used for materials causing irritation, sensitization, or other less severe health hazards.
    • Purpose: Pictograms provide immediate visual cues to workers about the type of hazard, aiding in quick recognition and risk assessment.
  4. Labeling Best Practices:
    • Readability: Labels should be kept clean and readable. If labels become damaged or worn, they should be replaced.
    • Location and Visibility: Ensure labels are clearly visible on containers and not obscured by other items or clutter.
    • No Alteration: Labels should not be altered or removed. If additional information is needed, it should be added in a way that doesn’t obscure the original label.
  5. Special Cases for Labeling:
    • Secondary Containers: Any container used to temporarily store hazardous materials needs a workplace label unless it’s only used by one person and emptied by the end of the shift.
    • Non-Routine Labels: For products generated as part of a process (e.g., dust, fumes), labels or signage in the work area can help workers identify and take precautions against airborne or particulate hazards.

Summary

WHMIS worker education and proper labeling are foundational to workplace safety when dealing with hazardous materials. WHMIS training ensures workers understand how to handle hazardous products safely and recognize risks through labels and pictograms. Supplier labels provide comprehensive information from the product’s manufacturer, while workplace labels are used for repackaged or relabeled products. Together, WHMIS training and labeling practices create a safer work environment, empowering workers to handle hazardous materials responsibly and respond to incidents effectively.
