Sample questions
GHS includes an environmental hazards group. How does WHMIS treat it?
It was not adopted, so WHMIS does not require that classification
It is mandatory, and every label must show the environment pictogram
It applies only to products that are shipped by rail or by sea
It replaces the health hazards group for products used outdoors
Show the answer
A. It was not adopted, so WHMIS does not require that classification
Canada did not adopt the GHS environmental hazards group into WHMIS. Suppliers may still show environmental information on labels and safety data sheets, but it is not required.

WHMIS was updated in 2015 to line up with which international system?
The International Maritime Dangerous Goods Code for shipping goods by sea and inland water
The Globally Harmonized System of Classification and Labelling of Chemicals
The ISO 45001 standard for occupational health and safety management
The NFPA 704 diamond system for emergency responders at fixed sites

B. The Globally Harmonized System of Classification and Labelling of Chemicals
WHMIS 2015 brought in the classification rules, label elements and 16-section safety data sheet of the Globally Harmonized System (GHS), which was developed by the United Nations. NFPA 704 is a separate North American emergency response marking and is not part of WHMIS.

A worker eats lunch at a workbench without washing after handling a lead-based product. Which route of entry is the main concern?
Ingestion
Inhalation
Injection
Absorption
Show the answer
A. Ingestion
Product on the hands is transferred to food and swallowed, which is ingestion. This is why eating, drinking and smoking are kept out of work areas and why hand washing matters.
