An occupational air quality assessment is a structured process to evaluate if the air in a workplace is safe for employees. It's especially important if hazardous substances are present (e.g., dust, fumes, vapours). Here’s a simplified breakdown of what’s involved:
| Step | Purpose |
|---|---|
| Risk Assessment | Identify hazards and affected workers |
| Walkthrough Inspection | Spot visible or reported issues |
| Monitoring Plan | Choose sampling type and timing |
| Sampling + Analysis | Measure actual exposure levels |
| Compare to WELs | Check compliance with legal limits |
| Recommendations | Fix or improve air quality controls |
| Retesting & Documentation | Maintain safe conditions and legal records |
