Janitors use hazardous chemicals on a daily basis, that’s why it’s important for them to know the ins and outs of WHMIS (Workplace Hazardous Materials Information Systems). With WHMIS training, cleaning staff will understand health risks, how to use personal protective equipment (PPE) correctly, and learn to follow procedures to prevent accidents.
Cleaners frequently use chemicals that can cause skin irritation, burns, or respiratory issues. But with WHMIS training they’ll have the knowledge to:
- Identify hazardous substances
- Understand safety data sheets (SDS)
- Recognize WHMIS labels and symbols
- Know what chemicals should never be mixed
- Use PPE effectively
- Respond to chemical spills
With training, cleaning crews can avoid accidental chemical exposures and workplace injuries. While employers can prevent regulatory non-compliance, which can lead to fines or legal consequences.
Common Cleaning Chemicals and Potential Hazards
| Product | Hidden Danger |
|---|---|
| Bleach | Releases chlorine gas when mixed with acids. |
| Ammonia-based glass cleaners | Generates chloramine gas if combined with bleach. |
| Hydrochloric-acid toilet bowl cleaners | Highly corrosive to skin, eyes, and metal. |
| High-strength disinfectants | Can trigger respiratory irritation without proper ventilation. |
| Industrial degreasers | May contain volatile organic compounds, harmful if inhaled. |
Key WHMIS Training Requirements for Cleaning Staff
1.Understanding WHMIS Labels and Symbols
Cleaning staff must recognize:
- Supplier Labels: Includes product identifiers, hazard symbols, and precautionary info.
- Workplace Labels: Required when chemicals are transferred to secondary containers.
- Pictograms: Such as corrosive, flammable, and toxic symbols.
2.Knowing What Not to Mix
Certain chemical combinations can produce deadly reactions:
- Bleach + Ammonia = Chloramine Gas (toxic to lungs)
- Bleach + Acids = Chlorine Gas (can be fatal)
- Hydrogen Peroxide + Vinegar = Acid (corrosive)
3.Using PPE Properly
Cleaning staff must wear appropriate PPE, including:
- Protective Gloves (for chemical resistance)
- Goggles or Face Shields (to prevent splashes)
- Respirators or Masks (when handling fumes or aerosols)
- Protective Aprons or Coveralls (to avoid skin contact)
4.Moving and Storing Chemicals
- Placing materials in a well-ventilated area away from any heat sources.
- Never transfer chemicals to unlabeled containers.
- Follow SDS instructions for dilution and usage.
Potential Health Risks for Cleaning Staff
Without proper WHMIS training, cleaning staff face:
- Respiratory Issues: From inhaling fumes (e.g., asthma, chemical pneumonitis).
- Skin Burns & Dermatitis: Due to prolonged exposure to corrosive substances.
- Eye Damage: Chemical splashes can cause blindness or severe irritation.
- Poisoning: Accidental ingestion or absorption through skin.
WHMIS training is not just a legal obligation, it’s a lifesaving necessity for janitorial staff. By understanding chemical hazards, proper PPE use, and safe handling procedures, cleaning teams can protect themselves and others while maintaining a safe workplace. Employers must ensure regular training updates to stay compliant and prevent avoidable accidents. Investing in WHMIS training today prevents workplace disasters tomorrow.
