How many hazard classes does WHMIS consist of?

• A. Four
• B. Six
• C. Eight
• D. Ten

Answer: (B)

The Workplace Hazardous Materials Information System (WHMIS) classifies hazardous materials into six hazard classes. Each class includes a variety of specific hazards, categorizing the materials based on their properties and the risks they pose to health and safety in the workplace. These six classes cover a range of hazards such as physical hazards (e.g., flammability, reactivity), health hazards (e.g., carcinogenicity, respiratory sensitization), and environmental hazards. Understanding these classifications assists in safely managing and handling hazardous materials, as it provides essential information such as proper labeling, safety data sheets, and employee training protocols. This systematic approach ensures that workers are adequately informed about the risks associated with the materials they may encounter, fostering a safer working environment.
