Best practices for on-site hazardous materials handling

Follow a clear plan before bringing hazardous products on site: identify materials, secure SDSs (safety data sheets), store correctly, label containers, train staff in WHMIS, and plan for transport and spills.

  • Maintain current SDSs for every hazardous product and keep them accessible on site.
  • Label all containers with content, hazards and date received.
  • Store incompatible chemicals separately and use secondary containment for liquids.
  • Train workers on WHMIS, PPE use, and emergency response, with refresher sessions documented.
  • Document inspections, incidents and corrective actions to support compliance and audit trails.
Keep a site-specific hazardous materials inventory and update it when products change.
