The Workplace Hazardous Materials Information System (WHMIS) has been the cornerstone of health and safety in Canada for decades. However, the integration of the Globally Harmonized System (GHS) fundamentally changed how we classify and communicate chemical hazards.
Often referred to as WHMIS 2015, this transition aligned Canadian safety standards with the rest of the world. But what exactly changed, and what do employers and workers need to know when getting certified today?
The Major GHS Updates: What Changed?
The shift to GHS wasn't just a regulatory formality; it completely overhauled the visual and written communication of hazards on the job site. The three most critical changes include:
- New Pictograms: The old black-and-white circular symbols were replaced with standardized red diamond-shaped pictograms. These are now universally recognized across international borders.
- Safety Data Sheets (SDS): The old Material Safety Data Sheets (MSDS) were replaced by the SDS. The new format mandates a strict, 16-section standardized layout, making it much easier for a worker to find emergency first-aid or handling info quickly.
- Signal Words: GHS introduced standardized signal words—specifically "Danger" (for high-risk hazards) and "Warning" (for less severe hazards)—to instantly communicate the severity of a product.
WHMIS Certification: Course Outline
A compliant training course covers the following essential topics:
- What is WHMIS? Understanding the purpose of the system.
- Roles and Responsibilities: Explores the specific duties of the employer, supervisor, and worker.
- GHS Updates: The transition to new warning symbols and Safety Data Sheets (SDS).
- Hazard Classes: A review of hazard classes and their potential health effects.
- Exposure Risks: Covers common organs affected by substance exposure and toxicity levels.
- Safe Handling: Proper procedures for the handling and storage of hazardous products.
Getting Certified: Online vs. Onsite Training
When it comes to getting your staff certified, you generally have two options. Both can satisfy general regulatory requirements, but the experience and application differ significantly.
What to Expect with Online WHMIS Training
Online training has become the industry standard for general workforce compliance. It is highly efficient, cost-effective, and flexible.
- Self-Paced Learning: Workers navigate through interactive slides, videos, and modules at their own speed.
- Standardized Testing: The course typically concludes with a 30 to 40-question multiple-choice exam.
- Instant Certification: Upon passing, a digital certificate and wallet card are usually generated instantly for employer records.
- Best For: Office staff, general laborers, retail workers, and new hires who need immediate onboarding.
What to Expect with Onsite WHMIS Trainers
Hiring a safety consultant to deliver instructor-led training at your facility provides a deeper, more tailored educational experience.
- Site-Specific Focus: A good onsite trainer will review the exact chemicals and hazards present in your specific workplace, rather than just speaking in generalities.
- Interactive Q&A: Workers can ask direct questions about the materials they handle daily and get immediate clarification.
- Hands-On Applications: Trainers can walk the floor with staff to point out proper storage protocols, eye-wash stations, and PPE requirements.
- Best For: Manufacturing plants, laboratories, construction crews, and environments handling highly volatile or specialized hazardous materials.
Frequently Asked Questions
Does my old WHMIS 1988 certificate still work?
No. The transition period for GHS implementation ended years ago. All workers exposed to hazardous materials must hold a current certification that includes the GHS standards.
Is general WHMIS training enough to be compliant?
General training (whether online or in a classroom) covers the fundamentals of the system. However, employers are legally required to provide site-specific training as well. This means showing workers exactly where the SDS binders are kept, what specific PPE is required for their tasks, and emergency procedures for their specific location.
How often do I need to renew my WHMIS certification?
While federal law does not specify a strict expiration date, most provincial health and safety authorities—and industry best practices—requires every 3 years you get retrained, or whenever new hazard information or new chemicals are introduced to the workplace.
