P602 provides the basic methodology, theoretical and practical knowledge to enable you to design simple LEV systems with proficiency. You’ll gain the knowledge to design systems that are effective in controlling hazards which have been identified. The course also covers the commissioning process, alongside how to check whether a Local Exhaust Ventilation (LEV) system is effective and functioning to the design specification.

Gain knowledge and understanding of:

1. The principles of good control practice and the role of LEV systems.
2. The significance of design considerations as well as the main principles and elements of an LEV system.
3. How to design simple LEV systems that can adequately control identified hazards.
4. The way to carry out the necessary measurements when commissioning a system. And also how to determine whether alocal exhaust ventilation system is effective and functioning according to the design specification.
5. Preparing appropriate records of the basis of design.


  • You must have successfully completed module P601 – ‘Thorough Examination and Testing of Local Exhaust Ventilation Systems’, or demonstrate equivalent knowledge.
  • You need to have a working knowledge of HSG258 Controlling airborne contaminants at work: A guide to local exhaust ventilation.

Who should attend:

You should consider this course if you are any of the following:

  • An engineer
  • A manager
  • A supervisor
  • A member of technical sales staff
  • An LEV technician
