Local exhaust ventilation (LEV) is one of the main measures used to control worker exposure to hazardous substances. It’s difficult to work out exactly how many systems there are in Britain, but the Health and Safety Executive carried out some research in 2006 and estimated that there were between 260,000 and 330,000 businesses that haveContinue reading “Designing and managing local exhaust ventilation”

Glove boxes are often used in the pharmaceutical industry to control highly toxic “active” agents used in drug formulations. In principle they should provide a high degree of protection for the user. The contaminant is completely contained inside an extracted enclosure while the worker is outside. So when we’re carrying out a risk assessment andContinue reading “Glove boxes”

It was a good meeting and I feel that HSE were willing to listen and take on board suggestions that I and otherContinue reading “Managing LEV systems – have things improved?”
