Identification of Asbestos in Bulk Samples by PLM P401

Asbestos bulk analysis plays a key role helping to identify asbestos in materials, to allow asbestos in buildings to be effectively detected and managed in line with the Control of Asbestos Regulations (CAR) 2012, Regulation 4. P401 – Identification of Asbestos in Bulk Samples by PLM gives analysts the knowledge and skills required to safely analyse bulk samples containing asbestos, identifying the specific asbestos component(s) as required in CAR 2012, Regulation 5.  

The requirement to be formally trained in asbestos analysis work is outlined in HSG248 Asbestos: The Analysts' Guide (2nd edition, July 2021), which states that any workers who are liable to be exposed to asbestos should be sufficiently trained in their area of asbestos work, to ensure they are not put at risk when working with asbestos. CAR 2012, Regulation 21 also states that all persons who analyse materials must be proven competent within an ISO/IEC 17025 laboratory, and this qualification is a step towards proving competence. 

Who is it for?

The qualification is suitable for anyone who is:  

  • Required to analyse bulk asbestos samples as part of their work 
  • Considering a career in asbestos analysis  
  • Responsible for managing asbestos laboratory analysts 

Level

The level of a qualification indicates the relative complexity and depth of knowledge and skills required to attain the qualification.  

This is a level 4 qualification in the BOHS qualifications frameworkequivalent to NVQ Level 4 (HNC). 

How is it delivered?

The P401 course will require at least 18 hours of study time, of which 14 hours will be taught (teaching and practical assessment) and 4 hours will be independent (in your own time). In addition there will be 5.5 hours of examination time.

Content / Learning outcomes

Overall aim
