Provision of fully independent asbestos assurance and verification of analytical air and bulk samples, providing increased confidence in the levels of associated asbestos fibre counts.

Independent assurance is to be split into two sections, fibre counting utilising phase contrast microscopy and bulk analysis utilising stereo microscopy examination and polarizing light microscopy; HSE will provide these services for the following: 1. Air monitoring assurance Air monitoring assurance will be based initially on analysis of 10% of air samples undertaken per analyst per month, however additional samples can be included as per the site Lead Asbestos Competent Person (LACP) or Magnox Central Improvement Programme (MCIP) request. If a low level of samples has been analysed by one analyst, the relevant site LACP will have discretion to select the number of required assurance checks to be undertaken. 2. Bulk samples assurance Bulk sample assurance will be based on the analysis of 5% of total samples being selected per analyst per month with a minimum of two samples per month, however additional samples can be included as per the site Lead Asbestos Competent Person LACP or Magnox Central Improvement Programme (MCIP) request. . If a low level of samples has been analysed by one analyst, the relevant site LACP will have discretion to select the number of required assurance checks to be undertaken.
