4 Stage Clearances & Certificate of Re-Occupation

Once removal within an enclosure has been completed, it is the responsibly of the Analyst to undertake a 4 Stage Clearance. This involves a thorough visual inspection of the enclosure, externally and internally, to ensure it meets acceptable standards.  A disturbed air test (clearance air test) is then undertaken to ensure the concentration of fibres within the air is below the clearance indicator value. When all stages have passed a Certificate of Re-Occupation is issued.

Leak Testing (enclosures)

During the removal of asbestos within enclosures it is highly recommended that air testing is undertaken to ensure the integrity of the enclosure. Leak Testing is undertaken to areas where potential breaches of the enclosure could occur or where access and egress to the enclosure is made. The testing is undertaken using Phase Contrast Microscopy and a Certificate of Fibre Concentration is issued.

Background / Reassurance Air Testing

During asbestos works outside an enclosure, prior to works commencing and after works have been completed it can be beneficial to undertake asbestos air testing. The testing is undertaken to establish the asbestos fibre levels within the air. This type of testing is also associated with external soil works where removal or disturbance of contaminated soils are undertaken. This type of testing is undertaken to the perimeter of the site and the weather conditions are documented on the certificate. All testing is undertaken using Phase Contrast Microscopy and a Certificate of Fibre Concentration is issued.

Personal Monitoring

On occasions, monitoring of operatives is required. Personal monitoring requirements must be considered when planning a job. When monitoring an asbestos removal job, the operative should give clear instructions about the purpose of the sampling. All sampling should be carried out for sufficient durations: shift duration (preferably 2-4 hour periods) or the duration of specific tasks being observed. When considering personal exposure, results should be reported as a 4-hour, time weighted average.

Hygiene Unit Clearance Certificates

The Hygiene Unit is used to decontaminate personnel who have entered the enclosure. To allow safe removal of the Hygiene Unit it must be clean and pass a clearance test. A certificate will be issued which must be fixed to the inside of the unit.

Asbestos Removal Contractor Compliance

Core undertake Contractor Compliance on asbestos removal projects to assist Clients. This work includes reviewing method statements, keeping logs of trained personnel (training dates, face fit dates & medicals), equipment checks, enclosure checks and daily site diaries. This work allows a Client to feel confident that the removal process is overseen independently to the removal company.

Mobile Asbestos Air Testing Laboratories

Our mobile laboratories are fully equipped to undertake all asbestos air testing and monitoring activities on-site, including the provision of all relevant certification.

“The HSE strongly recommends the use of accredited or certificated surveyors for asbestos surveys. The duty holder should not appoint or instruct an independent surveyor to carry out a survey unless the surveyor is competent.”
