MSDS (Material Safety Data Sheet)
An MSDS (Material Safety Data Sheet) is the predecessor to the modern SDS, used under the original WHMIS 1988 system. It has been replaced by the 16-section SDS format under WHMIS 2015/GHS.
What Is an MSDS?
A Material Safety Data Sheet (MSDS) was the hazard communication document used under Canada's original WHMIS (1988) and similar systems worldwide. It provided information on chemical hazards, safe handling and emergency procedures but did not follow a standardized format.
MSDS vs. SDS
- MSDS (old): Variable format (9 or 16 sections depending on jurisdiction), older classification criteria, no standardized pictograms.
- SDS (current): Standardized 16-section format under GHS, internationally consistent, uses GHS pictograms and hazard/precautionary statements.
Transition Timeline
Canada completed the transition from MSDS to SDS through WHMIS 2015. Since June 1, 2018, all hazardous products in Canadian workplaces must be accompanied by a GHS-compliant SDS, not the old MSDS format.
Update Your Chemical Library
If your workplace still has MSDS binders, they need to be replaced with current SDS documents. Make Safety Easy helps you digitize your chemical library, flag outdated documents and ensure every product has a current, GHS-compliant SDS.
