What does WHMIS stand for?\n\n

Workplace Hazardous Materials Information System.\n\nIt is a comprehensive plan for providing information on the safe use of hazardous materials used in Canadian workplaces.\n\n

What are the three main elements of WHMIS?\n\n

1. Cautionary Labels: On containers of hazardous products.\n2. Safety Data Sheets (SDS): Providing detailed hazard and precautionary information.\n3. Education and Training Programs: For workers.\n\n

What is a Safety Data Sheet (SDS)?\n\n

A technical document that provides detailed and comprehensive information about a controlled product, including:\n\n- Health effects of exposure\n- Hazard evaluation related to storage and handling\n- Emergency procedures\n\n

What are the responsibilities of the Employer?\n\n

• Provide workers with access to current Safety Data Sheets (SDS).\n- Ensure all hazardous products are clearly labeled.\n- Provide workers with education and training on how to handle products safely.\n\n

What are the responsibilities of the Worker?\n\n

• Attend WHMIS training sessions.\n- Follow safe work instructions and use personal protective equipment (PPE).\n- Report any situation where information is missing (e.g., a damaged or missing label).\n\n

What information must be on a Workplace Label?\n\n

1. Product Identifier: The name of the product.\n2. Safe Handling Instructions: Precautions to take.\n3. Reference to SDS: A statement indicating that a Safety Data Sheet is available.\n\n
