Assessment#
- Trace and identify
- Confirm the source product and identify all areas where the material may have been used.
- Conduct inspection for the spread of the product by visual assessment only using non-reflective black sticky tape (sand will be visible on the tape). Swabbing is not permitted.
- Apply tape to surfaces suspected of containing sand and visually assess for the presence of product.
- If product is present on the tape, conduct more localised tape testing to establish an inclusion zone.
- Visual inspections
- Perform surface tape lift to visually identify the presence of the product on all suspected surfaces affected by the use of sand.
- Inspect all vertical and horizontal surfaces (including porous surfaces).
- Inspect all furniture and toys.
- Inspect any stored items.
- Check external waste bins, as the school may have unknowingly disposed of the product. Include these in scope of remediation if contamination is found.
- Define affected areas
- Provide photographic evidence of all sand affected areas.
- Supply a site plan clearly marking locations of contamination.
- Remediation requirements
- Identify all items requiring removal based on surface tape lift evidence and visual assessment.
- If building materials are impacted and require removal, undertake a localised intrusive inspection prior to remediation to test and confirm the presence of any additional ACM that may be affected (for example, flooring below carpets).
- Provide a detailed inventory of items to be removed and those approved for in-situ cleaning.
- Defining the area in scope
- Use information gathered from surface sampling visual assessment to refine the scope of removal where possible.
- Include a buffer zone as a precaution.
- Preliminary air monitoring
Perform benchmark air monitoring within affected areas likely to be occupied, such as classrooms.
Remediation#
Work classification and responsibilities#
Licensed asbestos removal contractor
WorkSafe has classified this as Class A removal.
Licensed asbestos removalist will be responsible for the following:
- notification to WorkSafe to be done as immediate notification
- preparation of an Asbestos Removal Control Plan (ARCP)
- remediation under Class A controls
- disposal of all waste at an approved facility by a licensed Class A removalist.
Note: If the area can be confined to specific locations, cleaning may be completed using localised enclosure set up.
Licensed asbestos assessor
Must be engaged independently of the removalist to:
- perform air monitoring during remediation
- conduct a 4-stage clearance
- carry out any required sampling.
Stage 3 – clearance specific requirements
Stage 3 clearance will require dust disturbance and air monitoring. Swabbing is not acceptable.
Post-remediation#
Once remediation work is completed, the school must be issued with an asbestos clearance certificate from the licensed asbestos assessor prior to access being permitted. This certificate confirms that the area has been sufficiently decontaminated and is safe for reoccupation.
