Abstract

Laboratories engaged in the investigation of reactions involving the use of hazardous chemicals have a need to demonstrate the performance and safety of their fume hoods. This was done in the present work by using a tracer gas and a suitably modified infrared camera capable of viewing the movement of a tracer gas against a warm background. To further demonstrate the hood effectiveness, a simultaneous air sample is taken at the breathing zone of a manikin in place of an operator and analyzed for small amounts of the tracer gas.
