Safety Cabinet Solutions have completed a contract for AEA Technology, Oxford, UK, involving changes in work procedures to accommodate the use of a ductless fume cupboard.
Due to heating and ventilation issues, it was not possible to install ducted fumecupboards.
Safety Cabinet Solutions was asked to advise if it were possible to use recirculating carbon- filtered fume cupboards.
After completing a comprehensive chemical usage sheet and the analysis of this by the Erlab laboratory, it was deemed that, due to AEA's processes, the filter life would be too short (three months) to make a ductless fume cupboard a viable economic option.
Dale Dobson, managing director of Safety Cabinet Solutions, suggested a few slight alterations to AEA's work procedures, which would considerably increase the carbon filter life to a more acceptable 12 months or more.
After consultation with AEA Technology's safety officer and scientists, it was agreed that these changes were acceptable.
Three Toxicap 1624 cabinets with primary and secondary carbon filtration, complete with automatic filter condition system, were ordered and supplied together with a Flowcap vertical laminar flow cabinet.
