BOHS is one of the biggest occupational hygiene societies in Europe, and the only professional society representing qualified occupational hygienists in the UK. The Society as a whole offers membership to anyone with an interest in a healthy work environment. You can check out the benefits of membership and join online via their Membership section.

For a number of years BOHS have been the lead body in developing recognised professional training courses for specialists in the field of Local Exhaust Ventilation (LEV).

These courses are run by accredited LEV Training Course Providers , of which  OXYL8 is one.

“Proficiency” Qualifications

HSE’s LEV Guidance document, HSG258, directly refers to two of the BOHS ‘Proficiency’ qualifications; – ‘P601 Initial Appraisal and Thorough Examination and Testing of Local Exhaust Systems‘ and ‘P602 Basic Design Principles of Local Exhaust Ventilation Systems.

P601 is useful for anyone who will test ventilation systems (CoSHH statutory TExTs), and P602 is relevant for company engineers and managers who undertake design, manage the design process or oversee design projects.  A copy of the syllabus for each course can be downloaded here:
