Asbestos Air Testing & Monitoring in Chichester, West Sussex
Air testing and monitoring is a critical component of asbestos management in Chichester. Whether you require background air sampling before works commence, personal exposure monitoring during removal, or the mandatory four-stage clearance process following licensed asbestos removal, our BOHS P402-qualified analysts provide independent, UKAS-accredited air monitoring services across West Sussex.
Types of Air Testing We Provide in Chichester
Background Air Sampling
Background (baseline) air sampling is carried out before asbestos removal works commence in Chichester. This establishes the ambient fibre concentration at the site before any disturbance, providing a benchmark against which clearance air test results are compared. Background sampling is strongly recommended for all licensed removal projects and any work in occupied or partially occupied buildings.
Personal Air Monitoring (PAM)
Personal air monitoring involves attaching a sampling pump to operatives' lapels during asbestos removal works. The pumps sample the air at the operative's breathing zone throughout the working shift. Samples are analysed by phase contrast microscopy (PCM) or scanning electron microscopy (SEM) in our UKAS-accredited laboratory, confirming that fibre concentrations remain below the legal Control Limit of 0.1 fibres/cm³.
Enclosure Leak Testing
For licensed asbestos removal in Chichester carried out within a full containment enclosure, we carry out systematic leak testing of the enclosure perimeter before removal commences, ensuring no fibres escape to the surrounding environment.
Four-Stage Clearance Testing
Four-stage clearance is a mandatory process following all licensed asbestos removal in Chichester. The four stages are:
- Stage 1: preliminary visual inspection of the work area
- Stage 2: detailed visual inspection under good lighting
- Stage 3: air sampling — a minimum of five samples taken within the enclosure
- Stage 4: analysis and issue of a reoccupation certificate
Only when all four stages are passed can the work area be handed back for reoccupation. Our analysts are independent of the removal contractor — a legal requirement for licensed work.
Reassurance Air Sampling
Reassurance air sampling is available for Chichester properties where asbestos has been disturbed accidentally — for example during renovation works — and where the client needs independent confirmation that the area is safe. Results are typically available within 24–48 hours.
🔬 All air testing in Chichester is carried out by BOHS P402-qualified analysts. Laboratory analysis is UKAS-accredited to ISO 17025. Results include a full written report and reoccupation certificate where applicable.
Air Testing Costs in Chichester
Air testing costs depend on the type of sampling required and the number of samples taken. Four-stage clearance testing for a standard single-room licensed removal in Chichester typically costs £350–£600. Background sampling and personal air monitoring are priced on application.
