“WHMIS”, stands for “Workplace Hazardous Materials Information System”, is a standardized hazard communication system designed to provide essential information about hazardous materials used, handled, or produced in workplaces. It aims to empower workers with the knowledge needed to work safely with potentially dangerous substances, reducing the risk of accidents and injuries.
Examples:
- Chemical Container Labeling:
- WHMIS requires that all hazardous materials in the workplace be labeled with specific symbols, signal words, and hazard statements to indicate the potential dangers. For example, a chemical container may bear a WHMIS label with symbols representing toxicity, flammability, or other hazards.
- Material Safety Data Sheets (MSDS):
- WHMIS mandates the creation and availability of Material Safety Data Sheets (MSDS) for each hazardous substance. These sheets provide detailed information about the properties, hazards, safe handling procedures, and emergency measures related to the material. For instance, a worker consulting the MSDS for a cleaning solution would find information on proper ventilation, personal protective equipment (PPE), and first aid measures.
- Training Programs:
- Employers are required to provide WHMIS training to employees who work with or may be exposed to hazardous materials. Training covers understanding WHMIS labels, interpreting MSDS, and adopting safe handling practices. An example includes conducting regular WHMIS training sessions for employees in industries dealing with chemicals or hazardous materials.
- Emergency Response Planning:
- WHMIS necessitates the development of emergency response plans in case of accidental exposure or spills of hazardous materials. These plans outline evacuation procedures, first aid measures, and contacts for emergency services. An example is conducting periodic drills to ensure that employees are well-prepared to respond effectively to emergencies.
- Ongoing Communication:
- WHMIS promotes continuous communication about hazardous materials by requiring updates to labels and MSDS whenever there is new information about a substance’s hazards. An example involves promptly updating WHMIS labels and informing employees of any changes in the properties or risks associated with a given material.
