Asbestos Air Monitoring

Air monitoring is where a known volume of air is drawn through a filter and is analysed using Phase Contrast Microscopy to determine the fibre levels. This enables us to assess whether the area is safe to occupy. There are several different types of Asbestos Air monitoring:

Four Stage Clearance (4SC):

After the removal of asbestos or any repair or encapsulation works that might disturb any known asbestos in your premises, a thorough four-stage clearance assessment must be completed by an independent, UKAS accredited asbestos specialist to determine whether it is safe for reoccupation.

The 4SC process involves the following:

Stage 1 Preliminary check of site condition and job completeness.

Stage 2 A thorough visual inspection inside the enclosure/work area.

Stage 3 Air monitoring

Stage 4 Final assessment post-enclosure/work area dismantling

All four stages of 4SC assessment must be passed before a Certificate of Re-occupation (CfR) can be signed-off and the area is safe to return to the Client.
When it comes to four-stage clearance, our team is meticulous and can guide you through the process from start to finish, assisting you with any questions along the way and managing your expectations.
