NEW!! WHMIS 2015

The basis for hazard classification and communication in WHMIS is changing to adopt new, international standards for classifying hazardous chemicals and providing information in labels and safety data sheets. With the incorporation of the Globally Harmonized System of Classification and Labelling for chemicals (GHS) in WHMIS, the hazard classification and communication requirements of WHMIS 2015 have been aligned with those used in the United States and other Canadian trading partners. The new standards are being phased in across Canada between February 2015 and December 2018. 
What does this mean for you?

McMaster University Environmental and Occupational Health Support Services (EOHSS) has updated its current WHMIS program to include these changes. All changes will be covered under the new health and safety course WHMIS 2015 in which workers will be educated on both the old and new WHMIS systems.

During the three year transition period workers will be exposed to both systems of labelling, classification and communication and must be trained in both.

Am I required to complete this training if I have taken WHMIS at McMaster in the past?                                        All McMaster workers are required to take WHMIS health and safety training. In the past, McMaster University Environmental and Occupational Health Support Services (EOHSS) has provided three different levels of WHMIS training; WHMIS Core, Office WHMIS and WHMIS Update. WHMIS 2015 has replaced these courses and completion of the training is mandatory for all current and future employees.


WHMIS is mandatory training for anyone working with or in the proximity of hazardous materials.

The goal of this module is to familiarize you with WHMIS 1988 and WHMIS 2015 in order to ensure your safety throughout this transition period.
