5.4.3 Horizontal laminar flow hoods

These "clean benches" are present in a number of clinical, pharmaceutical and laboratory facilities strictly for product protection.  They provide a high quality environment within the work chamber for manipulation of non hazardous materials. 

Caution: since the operator sits in the immediate downstream exhaust from the "clean bench," this equipment must never be used for handling toxic, biohazardous, radioactive or sensitizing materials.
