4. Safety in the Workplace: WHMIS The Workplace Hazardous Materials Information System (WHMIS for short) is a comprehensive national system for safe management of hazardous chemicals which is legislated by both the federal and provincial jurisdictions. In summary, WHMIS delivers the necessary information by means of: cautionary labels on containers of controlled products the provision of an MSDS for each controlled product a worker education program The ultimate goal is to create a safer workplace by providing workers with the knowledge and tools to enable them to work safely.
