CCHRC – Controlling Health Risks in Construction

Industry feedback has led to BOHS developing the Certificate for Controlling Health Risks in Construction (CCHRC) course, to assist construction employers in up-skilling their existing safety-trained workforce in the basics of health risk management and control.

Who is it for?

This course has been designed to give site supervisors and site managers an understanding and awareness of the health hazards they could come across on a construction site, such as dusts, noise and gases. It informs you about the most common health risks associated with construction work and how to control these risks to reduce workplace ill health for yourself and your colleagues. 

Workers who have functional responsibility for managing the health risks and controls on a construction site.  

This includes:  

  • Site supervisors 
  • Site managers 

It may also be suitable for people who wish to progress into these job roles. 


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

This is a level 2 qualification, comparable to the NEBOSH Health and Safety at Work Qualification. 

How is it delivered?

The course comprises 8 hours of learning time. This includes approximately six hours of teaching time over one day, and up to two hours of independent study before the taught course.
