ATaC Update - HSG248’s Approach to Bulk Analysis of Non-Asbestos Detected Sampling

ATaC continues to keep members updated on the Health and Safety Executive’s evolving approach to bulk analysis of non-asbestos detected (NAD) sampling.

Since our last update on September 25th, ATaC has been actively discussing members’ concerns with key stakeholders. We remain committed to ensuring your voices are heard as these changes unfold.

Recent Developments

On July 28th,  Darren Evans of AEC on behalf of ATaC attended a UKAS Technical Advisory Committee workshop to represent members' interests regarding proposed changes to NAD sampling guidance.

Key discussions focused on the methodology for categorising NAD materials, resulting in agreed actions around adjusting minimum examination times. Category A and B samples will now have reduced times, easing the burden on lab productivity.

This positive outcome shows a willingness to address industry concerns. By attending these discussions, ATaC continues to advocate for members and provide crucial feedback to shape more workable NAD sampling requirements.

Remaining Challenges

There are still concerns regarding the HSE's proposed 10-minute inspection time and 2-point allocation for certain category B materials like fibre-cement and calcium silicate boards. ATaC and other stakeholders argue, when these products contain asbestos, the fibres are readily visible. These products also comprise a large share of NAD analysis requested by clients. Extended inspection wasting resources on straightforward samples.

Simpler analysis would ease the burden on labs while still reliably detecting asbestos. By continuing to press for sensible categorisation, ATaC advocates for feasible standards that serve both labs and clients.

A Path Forward

The classification of certain materials under category B remains unresolved, so the HSE has extended the timeline for industry feedback on the new NAD proposal. An additional workshop will allow for further discussion.

Even as requirements continue to evolve, ATaC remains dedicated to representing members' interests. Your perspectives inform our ongoing advocacy efforts. Please contact Robert Southall at if you have any questions or require further information.

By keeping members informed and conveying your concerns, ATaC continues working to shape feasible standards that serve our industry. We appreciate your engagement and assistance in this process.
