Safety Advice Centre Ltd hold UKAS accreditation to ISO 17025 for asbestos air monitoring and four stage clearance activities.`
Our Analysts participate in the routine externally audited RICE scheme along with regular in-house assessments to ensure our customers receive the highest possible standards of quality and service. As a minimum, all analysts hold the following ‘British Occupational Hygiene Society’ (BOHS) qualifications:
- P403 Asbestos Fibre Counting (PCM); and
- P404 Air Sampling of Asbestos and MMMF and Requirements for a Certificate of Reoccupation following Clearance of Asbestos

Four-Stage Clearances
Undertaken following the removal of asbestos by a licensed asbestos removal contractor.
It involves four stages, undertaken by an analyst, from a UKAS accredited laboratory:
Stage 1
Preliminary check of site condition and job completeness.
Stage 2
Thorough visual inspection.
Stage 3
Clearance indicator air sampling for the Certificate for Reoccupation.
Stage 4
Final assessment post-enclosure and dismantling of work area.
On successful completion of the four stage clearance, the Certificate of Reoccupation will be issued, indicating the work area is now safe for reoccupation and that the area is free from dust and debris and any asbestos has been removed in full or appropriately encapsulated.
Our collaborative approach to the four-stage clearance ensures that analysts are available 24/7 providing clients and contractors with the service levels required in this high risk industry.

Explore our range of tests
Our commitment to excellence is reflected in the rigorous testing standards we uphold. From asbestos analysis to air monitoring, our comprehensive range of tests is designed to deliver reliable results you can trust.
Undertaken in circumstances where confirmation is needed that residual airborne fibre concentrations are less than 0.01f/ml.
Undertaken to establish the effectiveness of environmental controls employed whilst undertaking the removal of asbestos materials and to ensure airborne respirable fibres are not being released from work enclosures.
Undertaken to establish the fibre concentrations during any activity which may lead to airborne asbestos contamination.
Personal sampling is used:
- To check the effectiveness of control measures i.e. that engineering controls are working as they should, to their design specification and do not need maintenance or repair;
- To find out whether a control limit is exceeded;
- To confirm the appropriate selection of RPE or whether RPE selection is providing the appropriate degree of protection;
- To determine whether the action level is likely to be exceeded;
- For medical surveillance records;
- To support current and future risk assessments.
