What the Course Entails and Exam Details

The WHMIS curriculum covers essential hazard communication principles updated to align with the Globally Harmonized System (GHS).

Key topics covered in the training syllabus include:

• Hazard Classification: Differentiating between physical hazards (such as flammable liquids, compressed gases, and corrosives) and health hazards (such as toxic substances, carcinogens, and skin irritants).
• WHMIS Pictograms: Identifying and interpreting the standard hazard symbols, including flame, skull and crossbones, biohazard, corrosion, and gas cylinder icons.
• Product Labelling: Understanding the required components on both supplier labels and workplace labels, including product identifiers, signal words, hazard statements, and precautionary measures.
• Safety Data Sheets (SDSs): Navigating and extracting vital safety information from the standardized 16-section Safety Data Sheets.
• Rights and Responsibilities: Understanding the legal rights of workers under health and safety legislation, as well as employer and supplier obligations.
• Emergency Response and PPE: Selecting appropriate Personal Protective Equipment (PPE), executing emergency first aid, and managing accidental chemical spills.

What to Expect in the Final Exam

The WHMIS final examination evaluates your ability to interpret hazard labels, analyze Safety Data Sheets, and apply safety protocols in real-world scenarios.

• Question Format: The test consists of multiple-choice questions and true/false items.
• Passing Score Requirement: Candidates must achieve a minimum score of 80% to earn their official WHMIS certificate.
• Time Limit: Test-takers are typically allotted 45 to 60 minutes to complete the exam, though self-paced online modules may allow additional time.
