PPT-SAFE USE OF CHEMICAL FUME HOODS

Modified from University Of South Carolina The chemical fume hood is the most important engineering control that removes hazardous fumes and other airborne contaminants in a laboratory workers breathing zone  Any procedure or experiment that involves the use of hazardous chemicals needs to be contained inside a fume hood to control the release of contaminants in the laboratory  If you plan to work with chemicals that release toxic corrosive or flammable fumes mists or particulates you must handle these materials inside a chemical fume hood  It is necessary to follow these guidelines to optimize the performance of the chemical fume hood. pdf Date issued July 2012 Version 10 Previous review dates December 2013 Next review date December 2016 Related documents COSHH Guidance Note UoB Estates WI 6 July 2011 Governing policy UoB Statement of Health Safety Policy Guidance to policy Health How they work & when they don’t.. 2.
