Vicki, What kind of business/ industry are you in? Someone who works in a coal mine or biomass plant, or a diver for example then yes. Someone who drives a bus or a checkout no. If the work involves a measure of cardio pulmonory stress or exposure to inhalable whatevers it's either a good idea or required by regs. If it's not required then I wouldn't do it, not because the data is of no use but because I'm pretty sure you will have something that is then covered by data protection and all the fun and games that brings, Jim

Hello, Thank you for your responses. I work for an engineering firm and we perform welding and grinding. The extraction system has been identified as not fit and we are in the process of getting that changed. I will also go and have a look at the link as well and get my head into that as well. Vicki

Vcollier, I would be interested to know who "we" are. It would be dangerous on so many levels for anybody other than occupational health specilaists to be carrying out lung function tests, irrespective of the substances involved or the reason for the tests. Lung function tests are identified by legislation and/or occupational health assessments, whether for baseline or other testing and my advise would be that to avoid falling foul of of disability provisions in the Equality Act, data protection, common law of confidentiality and contract issues, these tests should only be undertaken by appropriate specialists. Regards. DJ.
