What is the difference between WHMIS 1988 MSDS & WHMIS 2015 SDS Formats

The Difference Between WHMIS 1988 MSDS & WHMIS 2015
Health Canada has aligned the Workplace Hazardous Materials Information System (WHMIS) with the widely recognized Globally Harmonized System of Classification and Labelling of Chemicals (GHS). WHMIS will now be referred to as WHMIS 1988 and the newly updated GHS and WHMIS will be referred to as WHMIS 2015. The entire process was completed in 3 phases, with the final phase being completed on December 1st, 2018.

WHMIS 1988 vs WHMIS 2015 FAQ
WHMIS was updated to align with the Globally Harmonized System of Classification and Labelling of Chemicals (GHS) which provides a more standardized approach to hazard communication in Canada. This also enables Canadian workplaces to communicate hazards more effectively with other countries that have adopted GHS.
The purpose of WHMIS 2015’s hazard groupings is to make it easier for workers to identify and understand the specific health hazards associated with a workplace product or substance.
Under WHMIS 2015, supplier labels must show the product identifier and supplier identifier, as well as standardized pictograms, signal words, hazard statements, and precautionary statements.
WHMIS 1988 had six classes of hazardous materials, while WHMIS 2015 has expanded to include three major hazard groups: physical hazards, health hazards, and environmental hazards.
Employers who fail to comply with WHMIS 2015 may result in fines of up to $1,000,000 and legal action due to endangering the safety of their workers.
