1 UV light and Biosafety Cabinets

2 Potential UV Hazard Hazard: Ultraviolet light (UV-C)
Recommendation: Switch off UV while working “UV-C does not penetrate skin, but is absorbed by organic materials… therefore used as germicidal …” in biological safety hoods. UV-C Maximum Exposure Limit: < 1 minute (100 uW/cm2) Source: < Source: (

3 Biological Safety Cabinets: UV-C
For biological sterility, either UV light OR blower fan should always be ON

4 Biological Safety Cabinets
Blower fan will not turn on unless hood is open ~3 cm

5 Biological Safety Cabinets
Recommendation: Switch off UV while working Switch on fan to preserve sterility Fan UV
