Environmental Services Group (ESG) was retained to develop an asbestos abatement scope for a semi-detached residential property damaged during a windstorm. The damage affected asbestos-containing cement siding also known as Transite cement, requiring abatement in accordance with Ontario’s Asbestos Regulation (O. Reg. 278/05).
Scope of Work
The assessment focused on outlining abatement requirements to safely remove and replace the damaged asbestos-containing siding while minimizing exposure risks. ESG reviewed the material’s condition and provided recommendations for compliance with provincial safety standards.
Key Activities
- Initial Assessment: Confirmed asbestos content through bulk sampling analysis performed by an independent certified laboratory, identifying the siding as asbestos containing, non-friable but hazardous when disturbed.
- Regulatory Guidance: Prepared a detailed scope referencing O. Reg. 278/05, including methods for safe removal using manual tools (Type 1 Operations) or, if necessary, power tools under more stringent Type 3 Operations protocols.
- Recommendations: Advised full removal of the damaged siding to prevent potential hazards from broken tiles and ensure the integrity of repairs.
Findings and Recommendations
- Non-friable asbestos-containing siding can be safely removed under Type 1 Operations if wetted and manually removed.
- Use of power tools, if required, necessitates compliance with outdoor Type 3 Operations due to the risk of airborne fiber release.
- Advised against partial repairs or tie-ins to damaged tiles to maintain material integrity and prevent future hazards.
Outcome
ESG’s abatement scope enabled the client to proceed with safe and compliant asbestos removal, ensuring worker and occupant safety while mitigating long-term risks associated with asbestos exposure.
