Are you concerned about the presence of asbestos in a property you own or manage?
Air monitoring can establish the level of risk.
If you’re planning asbestos removal work, the law requires air monitoring and 4-stage clearance testing to be conducted
by a UKAS accredited laboratory that is independent from the asbestos removal contractor.
Our dedicated analytical team provide a full range of air testing services during asbestos removal/remediation work.
We are a UKAS accredited testing laboratory No.7567 and can provide all forms of asbestos air monitoring.
All our work is carried out in accordance with documented in-house procedures based on HSG 248 The Analysts Guide for Sampling, Analysis
and Clearance Procedures, current legislation and UKAS publications.
Furthermore, all of our authorised personnel are trained to a minimum BOHS P403 Asbestos Fibre Counting & P404 Air Sampling and
Clearance Testing of Asbestos.
In addition, we are a UKAS accredited testing laboratory No.7567 and can provide all forms of asbestos air monitoring.
Ensuring safety is paramount, therefore we conduct compliance monitoring to check exposure doesn’t exceed the control limit – which is calculated over a 10 minute or 4 hour period.
When any asbestos removal work is carried out, under the terms of an HSE Asbestos Removal Licence, you need to obtain a Certificate of
Reoccupation – as required in the Control of Asbestos Regulations 2012. This must be issued by an independent third-party laboratory, which
must be accredited by the United Kingdom Accreditation Service (UKAS) to ISO 17025.
The Certificate of Reoccupation can only be issued once the UKAS Laboratory has confirmed the 4-stage clearance has been completed to the necessary standard, as follows:
Preliminary check of site
condition and job completeness
A thorough visual inspection inside the enclosure/work area
Clearance Air Testing
Final assessment post-enclosure/work area dismantling
If any of the stages are failed, remedial work will be carried out before the test is repeated.
The analyst will complete and issue documentation showing the performance of the contractor at each stage and detailing any failures and remedial action on the Certificate of Reoccupation. You must retain a copy of this for your records for 40 years.
When Stage 4 has been passed the clearance on the decontamination unit (also known as the ‘hygiene facility’) can begin.
However, the inspection on the hygiene unit may begin upon successful completion of stage 3 of the 4 stage clearance.
If at any point the hygiene unit is used during the 4th stage then the inspection process must start again. The analyst must visually inspect and air test the unit including a disturbance of all surfaces in the dirty and shower areas. In this case, only Stages 2 and 3 of the four-stage clearance are required.
