Directory entries are listed both alphabetically and regionally. The address listed is the company’s main office: if the company has other offices, these are listed separately within the entry. The contact listed in the entry is a member of the BOHS Faculty of Occupational Hygiene. Though regionally segmented for the purposes of this publication, please bear in mind that many companies do offer nationwide coverage. The main part of the entry is a summary of the company’s areas of expertise in occupational hygiene and related topics. This information has been provided by the company: please be aware that BOHS cannot accept responsibility for any inaccuracies relating to this specific information. The company’s entry may also include other services peripheral to the offered occupational hygiene services. Where a company lists accreditations for those peripheral services, users of the directory may wish to verify these via the relevant accreditation body.
