Asbestos still kills around 5000 workers each year as a result of past exposure to asbestos.

Managed Survey

The purpose of a managed survey is to locate the presence and extent of all suspect asbestos containing materials (as far as reasonably practicable). The condition, any damage and the risk during normal occupancy, including future maintenance works will be reported on in the material risk assessment and recommendations section of the report.

There will be minor intrusive sampling work where necessary. Our report will include a material risk assessment and recommendations.

Refurbishment and Demolition

A refurb and demolition survey are needed before any refurbishment or demolition work is carried out. This type of survey is used to locate and describe, as far as reasonably practicable all ACMs in the area where the refurbishment work will take place or in the whole building if demolition is being planned. The survey will be fully intrusive and involve destructive inspection, as necessary, to gain access to all areas, including those that may be difficult to reach. A refurbishment and demolition survey may also be required in other circumstances, e.g. when more intrusive maintenance and repair work will be carried out or for plant removal or dismantling.

Sampling Strategy for Asbestos Material

The object of carrying out sampling is to identify the nature, extent and condition of any visible asbestos material. After sampling, any friable or broken material is sealed whilst the samples are double sealed in polythene bags, which would not give rise to any dust release. Care is taken to prevent cross contamination of samples and to ensure that sampling does not impair the structural integrity of the building or plant. Where sampling was undertaken it was done so to cause minimum possible potential risk to the health of the surveyor, the occupants of, and visitors to, the building and to cause minimum nuisance.

As required under the Control of Asbestos Regulations, dust release in sampling must be reduced to as low a level as is reasonably practicable. An assessment of likely dust release dictated the need for, and the type of, precautionary measures. This may have included the use of personal protective equipment, isolation of the sampling areas, wetting of the material to suppress dust release and an appropriate cleaning process. The actual strategy adopted depends upon the material to be sampled e.g. friable boiler lagging or asbestos cement sewage pipes.

Method of Bulk Sample Analysis

At the end of the site works, any samples of material taken as part of the survey were submitted to SATS for analysis. This laboratory is UKAS accredited for fibre sampling and identification. When present, asbestos fibres were identified using documented in-house techniques following the optical dispersion staining method described in Health & Safety Executive Publication HSG 248: Asbestos: The analysts’ guide for sampling, analysis and clearance procedures.
