ESSENTIAL AIR MONITORING FOR ASBESTOS

Air asbestos monitoring from trusted experts

As a popular London asbestos air testing company, we work locally in the capital, nationally across the UK, and even abroad to test air to identify the presence of dangerous asbestos. As a UKAS accredited (4026) company, we'll test the air at your place and pin down any asbestos risks you face, providing solutions as well as invaluable intelligence.

Tiny particles of asbestos can cause terrible health problems. We carefully carry out asbestos air monitoring to reassure you, and we'll also remove the asbestos for you if necessary.

Our asbestos air monitoring services and asbestos re-inspections include intelligent background sampling and leak sampling (also called enclosure check sampling), and reassurance sampling. It all falls under the 4-Stage clearance system. Our vehicles have been fully converted into mobile laboratories, which means we carry out the air monitoring of samples using phase contrast microscopy, and we can do it from virtually anywhere in the UK.

We also provide a 24 hours per day, 7 days per week service on request and have an emergency call-out service as well, designed for those times when safety can't wait. And all of our asbestos inspection services are provided in accordance with ISO 17020.

Air monitoring is vital before, during, and on completion of the removal of asbestos materials. It is essential to find out if any exposure has taken place or will take place in the future, and check the containment measures put in place are good enough. We also carry out air testing after completion of any works to verify the area is safe regarding stage 3 of the 4-stage clearance procedure.

Because asbestos air testing can only be carried out by a UKAS accredited laboratory, we're a perfect choice. A professional Environmental Inspection will reveal the action needed depending on your situation, and we are happy to advise you about every aspect of a workable strategy for air monitoring.

Different types of air monitoring for asbestos

We offer a range of different air testing types for asbestos:

Background Monitoring to establish the amount of asbestos in the air before work starts
Leak Monitoring to examine the air outside the enclosure while asbestos is being removed
Reassurance Monitoring to show the air is free from fibres
4-Stage Clearance Monitoring, so you can get your Certificate of Reoccupation
Personal Monitoring to check employee exposure levels

The severe health risks presented by asbestos in buildings means asbestos air tests are a vital safety step. So pick a professional – this is no job for amateurs.

What is 4-stage clearance monitoring?

Clearance Monitoring must be carried out by a UKAS accredited company after licensable removal, and it involves four separate stages:

Stage 1 – A preliminary check of the condition of the site and the standard the job has been completed to
Stage 2 – A detailed visual inspection inside the enclosure where work is taking place
Stage 3 – The air monitoring itself
Stage 4 – A final assessment post-enclosure, once the working area has been dismantled

The area is only safe for people to enter once all four stages are completed.

About PCM, SEM and TEM

We usually use Phase Contrast Microscopy or PCM to test the air for asbestos. Now and again we use Scanning Electron Microscopy – SEM – or even Transmission Electron Microscopy, TEM. If we need to use either of them we’ll discuss things with you first.

Where do I usually find asbestos in a building?

No, there isn’t a safe level. On the other hand some studies show buildings containing asbestos in good condition have an airborne concentration up to 500 fibres per cubic metre. While it isn’t a safe level, it’s safer than the three decade-old original clearance indicator of 0.01 fibres per ml.
