Final answer:
The Workplace Hazardous Materials Information System was introduced to ensure employers and workers have the necessary information on hazardous materials and to mandate comprehensive safety practices in the workplace.
Step-by-step explanation:
The Workplace Hazardous Materials Information System (WHMIS) was introduced to address the need for comprehensive information on hazardous materials in the workplace. Its establishment was to ensure that workers and employers have access to the necessary information on chemical hazards through proper labeling, availability of safety data sheets, and adequate training. Regulations, such as those issued by the Occupational Safety and Health Act (OSHA), mandate employers to provide a safe working environment by finding and correcting safety and health hazards, communicating information about workplace risks, and ensuring that necessary precautions, such as using safer chemicals and efficient ventilation systems, are in place. The implementation of WHMIS helps in achieving these goals, by enabling better identification, evaluation, and control of workplace health and safety risks associated with hazardous materials.
