Air Monitoring, Clearance Inspections and Reoccupation Following the Removal of Asbestos IP404

IP404 Air Monitoring, Clearance Inspections and Reoccupation Following the Removal of Asbestos is the third in the suite of international asbestos qualifications. For asbestos removal and remediation projects, an independent asbestos assessor should check that control measures are effective and that the affected area is safe to re-occupy at the end of the project. This qualification covers the skills and knowledge an asbestos assessor needs, from air monitoring and clearance testing through to reporting findings and issuing a clearance certificate. 

Who is it for?

The qualification is suitable for anyone who: 

  • Undertakes clearance inspections and air monitoring of asbestos as part of their work (e.g. asbestos assessor); 
  • Issues clearance certificates after asbestos clearance procedures. 


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.  

Different countries use different levels, but this qualification is comparable to level 4 in the Regulated Qualifications Framework in England and level 5 in the European Qualifications Framework. 

How is it delivered?

The IP404 course will generally run over three consecutive days and include 16 hours of study time. This consists of 14 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 for three weeks, but should still include 16 hours of study time.
