how does whmis provide information about hazardous chemicals

WHMIS (Workplace Hazardous Materials Information System) provides information about hazardous chemicals primarily through three key components: labels on chemical containers, safety data sheets (SDS), and worker education programs. Labels give immediate visual warnings and precautionary details. Safety Data Sheets provide comprehensive information on hazards, safe handling, storage, emergency procedures, and first aid. Worker education programs ensure employees understand the hazards and how to protect themselves. WHMIS also classifies hazardous products into physical and health hazard groups with specific hazard classes to clearly communicate risks. This system is aligned with the Globally Harmonized System (GHS) for consistent international hazard communication.
