What Is WHMIS and Why Does It Matter in Dental Clinics?
WHMIS (Workplace Hazardous Materials Information System) governs the safe handling of hazardous materials in Canadian workplaces.
In dental clinics, this includes:
- Surface disinfectants
- Sterilization chemicals
- X-ray processing materials
- Cleaning agents
- Compressed gases
Failure to comply can result in Ministry of Labour penalties.
Is WHMIS Training Mandatory for Dental Offices in Ontario?
Yes.
Ontario employers must:
- Provide WHMIS training to employees
- Ensure staff understand hazard symbols
- Maintain accessible Safety Data Sheets (SDS)
- Label hazardous materials correctly
Documentation must be available upon inspection.
Who Requires WHMIS Training in a Dental Clinic?
WHMIS training applies to:
- Dentists
- Hygienists
- Assistants
- Sterilization technicians
- Cleaning staff
- Administrative staff exposed to chemicals
Training should occur upon hiring and whenever new hazardous products are introduced.
How Often Should WHMIS Be Updated?
While regulations may not specify annual renewal, best practice recommends:
- Annual refresher training
- Updates when new materials are introduced
- Documented retraining when procedures change
Regular review reduces risk.
What Inspectors Look For
Workplace inspectors may review:
- Proof of staff training
