WHMIS 2015 study guide
WHMIS 2015 · Work through your exam, one topic at a time.
WHMIS 2015 - the Workplace Hazardous Materials Information System aligned with the Globally Harmonized System - is Canada's workplace hazard communication standard. It is not a single national certificate exam; rather, workers, supervisors, and employers must be educated on it, and many employers and training providers verify that education with a written assessment. Candidates are typically workers handling, storing, or working near hazardous products, plus supervisors, managers, joint health and safety committee members, and anyone who needs to understand supplier labels, workplace labels, Safety Data Sheets, and hazard classes. This independent study page organizes preparation around four domains: WHMIS legislation and GHS alignment; hazard classes and pictograms; labels and supplier/workplace label requirements; and Safety Data Sheets and worker education. The WHMIS 2015 study guide has 4 sections and about 2,015 words.
01WHMIS Legislation and GHS Alignment
This domain tests the legal architecture behind WHMIS 2015: which level of government makes which rule, how the Canadian regime maps onto the Globally Harmonized System (GHS), and what suppliers and employers each owe. Questions often turn on the federal/provincial split rather than on chemistry.
459 words, about 2 min02Hazard Classes and Pictograms
This domain tests the 31 hazard classes, the difference between a class and a category, and the mapping from hazard to pictogram and signal word. Most exam items ask you to classify a product from a short property list and then select the correct symbol.
589 words, about 3 min03Labels and Supplier/Workplace Label Requirements
This domain tests what must appear on a supplier label, when a workplace label is required, and what a workplace label must contain. Exam items often present a decanting or damaged-label scenario and ask which label rule applies.
475 words, about 2 min04Safety Data Sheets and Worker Education
This domain tests the 16-section SDS format, what employers must do with SDSs, and how education differs from training. Exam items often ask which SDS section answers a practical question, or which SDS update rule is correct.
