BOHS Approved Course Provider

Occupational Hygiene is the science of recognising, measuring, and evaluation employee’s exposures to as wide range of physical and chemical hazards. Clients come to us when they have concerns about the levels to which their employees are exposed, but are struggling to evaluate the risk through conventional subjective risk assessment procedures.

Quantification of exposure, something unusual in many areas of risk assessment, is a powerful tool in defining the level of risk and evaluating the need for appropriate control measures. Occupational hygiene has been repeatedly shown to be a cost effective means of evaluating risk and is also of great value in defending litigation. Allow our experienced occupational hygienist to guide you through the world of Workplace Exposure Limits and CoSHH Assessment. This is one of Integral HSE’s core activities.

We are an approved supplier of British Occupational Hygiene Society courses. These courses are presented by Integral HSE to a set syllabus before being examined and certificated by the accreditation body.

Case Study 1

Man in Welding Mask


Milton Keynes Pressings Ltd Were unsure about the levels of welding fume to which their employees were exposure during wide variety of fabrication tasks. There were particularly concerns that the levels of risk might be higher while welding plated steels.


An extensive programme of personal exposure monitoring was carried out on all welding tasks throughout their production facility. This identified those areas where exposures where control was adequate and did notrequire further improvement actions where required, In those areas where improvements were required detailed advice was given on the installation of local exhaust ventilation systems and the choice of suitable respiratory protective equipment.
Where installation work was required by an outside contractor this was reviewed and validated by Integral HSE post installation to ensure that control of fume was adequate.

Resulting Changes

The client is now confident that their employee’s exposures are acceptable and the workforce is benefiting from improved air quality while welding.

Case Study 2

Clean Room


CEFAS operate a large number of LEV systems in their laboratory facilities. They wished to develop an LEV Management System to ensure that all systems could be managed adequately from pre use checks through to statutory inspection requirements.


Key performance indicators were identified and benchmarked to ensure that all pre-use checks and routine inspections were suitable and sufficient. Users and directly responsible managers where trained in basic measurement techniques and qualitative smoke testing.

Resulting Changes

Documentation was developed to ensure that all stages of the LEVs management was adequately recorded without generating an undue work burden. As a result CEFAS’s LEV systems are now probably some of the best managed in the country.
