Suppliers must provide which of the following to comply with WHMIS regulations?

Compliance with WHMIS (Workplace Hazardous Materials Information System) regulations is primarily concerned with ensuring safety and health information regarding hazardous materials is effectively communicated in the workplace. Suppliers play a crucial role in this process by providing Material Safety Data Sheets (MSDS), which are now referred to as Safety Data Sheets (SDS) under the GHS (Globally Harmonized System).

These data sheets contain important details about chemical substances, such as their properties, handling instructions, potential hazards, and emergency response measures. By supplying this information, suppliers enable employers and workers to make informed decisions regarding the safe use and handling of hazardous materials. This ensures safer working environments and helps to prevent accidents or health risks associated with hazardous substances.

The other options, while relevant to various aspects of workplace safety and employee welfare, do not directly align with the requirements dictated by WHMIS regulations for suppliers.
