What is WHMIS?

WHMIS stands for Workplace Hazardous Materials Information System. It is a nationwide system to provide information on hazardous materials used in the workplace. WHMIS affects workers, employers, suppliers, and regulators. Nova Scotia’s WHMIS Regulations place duties at any workplace covered by the Occupational Health and Safety Act where hazardous materials are used, stored, or handled.

WHMIS Classifications

WHMIS uses classifications, or classes, to group chemicals with similar properties or hazards. The Controlled Products Regulations specifies the criteria used to place materials within each classification. There are six (6) classes although several classes have divisions or subdivisions.
