Posted By Stuart Nagle Hi, Diane. This sounds interesting. I would have thought though that the best idea would be to have procedures for the tasks performed in the labs, best practice and all that for all persons working there, not just one rule for them and another for us, so to speak. It rather sounds like the Management of Health and Safety at Work Regulations - cooperation between persons sharing the same workplace, have slipped a little here. I would suggest the way forward is: 1) joint meeting of heads to explain the situation, identify the standards and requirements. Health & safety law/Regs etc. 2) a person(s) appointed as 'joint' auditors and examiners of the working practices, hazards, risks etc. 3) review current hazard/risk analysis 4) recommediations for working practices to be followed by 'all' in the labs - presnted again at joint meeting (thrash it out) 5) Training. implementation, audit, review, 6)implement, audit, review... 7 ) audit, review, audit review etc... Hope this helps Stuart Nagle
