Asbestos Fibre Counting (PCM) P403

Analysis of airborne samples plays a key role when managing asbestos in buildings in line with the Control of Asbestos Regulations (CAR) 2012. P403 – Asbestos Fibre Counting (PCM) gives analysts the knowledge and skills required to safely take air samples, prepare fibre counting slides, and accurately analyse these slides under a microscope to identify airborne fibre levels within the building or site. 

Who is it for?

The qualification is suitable for anyone who is:  

  • Required to undertake asbestos fibre counting as part of their work 
  • Considering a career in asbestos analysis 
  • Responsible for managing asbestos 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 framework, equivalent to NVQ Level 4 (HNC). 

How is it delivered?

The P403 course will generally run over two consecutive days and includes 11 hours of study time. This consists of 9 hours taught (teaching and formative practical assessment) and two hours of independent study (in your own time). 

The course can be delivered more flexibly, such as on one day per week over two weeks, but should still include 9 hours of teaching.
