Safe Use of Volatile Chemicals and Radioactivity in Biological Safety Cabinets

Work with biohazardous materials involving the use of volatile chemicals and/or radioactivity should exclusively be conducted in a biological safety cabinet that is vented outside the building.

Ducted Class II Type A2, Class II Type B1 and B2 (always hard-ducted), and Class III BSCs may be used with different amounts of chemicals/radioactive materials. Please review the following table for more specific details:

 

BSC CLASS / TYPE VOLATILE CHEMICALS RADIONUCLIDES
II / A2 If ducted outside building: minute amounts If ducted outside building: trace amounts
II / B1 Low levels Trace amounts
II / B2 Yes Yes
III Yes Yes
