Silica Low Risk Sites
The Healthy Site Alliance Silica Low Risk Site Campaign gives builders and contractors a smarter way to manage silica on site. Instead of relying on broad high-risk assumptions, our system helps verify that engineered controls are working, tasks are being managed correctly, and silica risk remains low during normal operations. With site-specific plans, monthly control checks, and professional reporting, HSA reduces compliance pressure, supports safer worksites, and gives builders confidence that contractor controls are being actively managed and documented.

Silica Low Risk Sites
HSA delivers a Control Verification & Risk Status Report that provides a clear, defensible view of how silica risks are being managed on site. Rather than relying on assumptions or generic compliance documents, the report is built on verified control measures, contractor compliance, and real site observations.
It confirms whether controls are in place, used correctly, and working effectively at the point of work, while identifying any gaps or failures that require action. The report also tracks contractor engagement and compliance across the site, giving builders full visibility and accountability.
This allows sites to confidently demonstrate a controlled, low-risk environment where appropriate, while providing practical actions to maintain and improve performance over time.
Silica High Risk Sites
Exclusion Zones
Designated areas around silica-generating tasks
Respirator Fit Testing
Verified fit for all exposed workers
Silica Register
Workers registered and tracked
Air & Health Monitoring
Documented exposure surveillance
Accredited Training
Completed by all relevant workers
If compliance cannot be demonstrated → work may stop.






Without a clear compliance system:
Every trade treated as high risk
Workers placed on the silica register
Mandatory health & air monitoring costs
Increased regulator and union scrutiny
Higher liability and insurance exposure
Silica Low Risk Sites
Validated Risk Assessments
Using verified exposure data
Low Risk Control Plan
Times, Locations and engineered controls to manage exposures
Control Verified
Checks confirm controls are in place as per plan
Controls Documented
Audit trail maintained at all times
Consistent Contractor System
All trades follow the same protocol






Without a clear compliance system:
Trade treated as controlled low risk
Not required to be on silica register
Mandatory health may not be required
Improved exposure control management
Healthier outcomes for workers
