Envirosphere Consulting provides independent asbestos clearance inspections in Auckland, Northland and Waikato following Class A and Class B asbestos removal work. Our clearance inspections assess whether asbestos removal areas have been adequately cleaned and are suitable for reoccupation. Services include Class A four-stage clearance inspections, Class B clearance inspections, clearance air monitoring and asbestos clearance certification, undertaken in accordance with New Zealand asbestos requirements.

Class A asbestos clearance inspections are required following licensed Class A asbestos removal work before the affected area can be returned to normal use. The four-stage clearance process includes a preliminary assessment of the removal area and enclosure, a thorough visual inspection for asbestos residue or debris, clearance air monitoring, and a final assessment following removal of the enclosure. Where all clearance requirements have been satisfied, an asbestos clearance certificate is issued.

Class B asbestos clearance inspections are undertaken following Class B asbestos removal work to assess whether the removal area has been adequately cleaned and is suitable for reoccupation. The inspection includes a thorough visual assessment of the removal area and surrounding surfaces for visible asbestos-containing material, debris or residue. Where the applicable clearance requirements have been satisfied, the findings are documented and an asbestos clearance certificate is issued.
Following licensed Class A asbestos removal work, a four-stage asbestos clearance inspection is undertaken by an independent licensed asbestos assessor before the affected area can be reoccupied. The process confirms that the removal area has been appropriately cleaned and that the applicable clearance requirements have been satisfied.
The enclosure, negative pressure system and asbestos removal work are reviewed to confirm the site is ready for clearance.
Every surface is carefully inspected for visible asbestos residue, dust or debris. This is the most critical stage of the clearance process.
Air samples are collected using calibrated equipment to assess airborne fibre concentrations and confirm the clearance air monitoring requirements have been satisfied.
Once the enclosure has been dismantled, a final inspection is completed and an asbestos clearance certificate is issued when all requirements have been met.
An asbestos clearance inspection is an independent assessment carried out following asbestos removal work to confirm that the removal area has been adequately cleaned and is suitable for reoccupation. The inspection checks that the applicable clearance requirements have been satisfied before the area is returned to normal use.
A Class A asbestos clearance inspection is required following licensed Class A asbestos removal work. In New Zealand, the clearance is undertaken by a licensed asbestos assessor and includes the applicable stages of the four-stage clearance process, including a thorough visual inspection and clearance air monitoring before the area can be returned to normal use.
Class A clearance inspections follow Class A asbestos removal work and involve the four-stage clearance process undertaken by a licensed asbestos assessor, including clearance air monitoring. Class B clearance inspections follow Class B asbestos removal work and primarily involve a thorough visual assessment to confirm that asbestos-containing material, debris and visible residue associated with the removal work have been satisfactorily removed.
For licensed Class A asbestos removal work, the clearance inspection and clearance certificate must be completed by a licensed asbestos assessor. Different requirements apply to Class B asbestos removal work, where the clearance must be undertaken by an independent competent person who is independent of the asbestos removal work.
The time required depends on the size and complexity of the asbestos removal area, the type of removal work and the condition of the area when presented for clearance. Class B inspections may be completed relatively quickly, while Class A four-stage clearance inspections generally take longer due to the visual inspection, clearance air monitoring and final assessment requirements. If an area does not satisfy the clearance requirements, further cleaning will be required before it can be reassessed.
Following licensed asbestos removal work, the applicable clearance requirements must be satisfied before the asbestos removal area is reoccupied. The clearance documentation provides independent confirmation that the required inspection process has been completed and that the area has satisfied the applicable clearance requirements.
