Class I Biological Safety Cabinet
Class I Biological Safety Cabinet
The class I biological cabinet is defined as an open fronted, negative pressure ventilated cabinet for personnel and environmental protection, with an unrecirculated air flow away from the operator. Class I cabinets are very similar in nature to a chemical fume hood except that they have a high efficiency particulate air (HEPA) filter on their exhaust outlet, and they may or may not be connected to an exhaust duct system. One limitation of the Class I cabinet is that is does not provide product protection.
Advantages
- Provides personnel and environmental protection
- It is similar in air movement to a chemical fume but usually has a limited fixed work access opening and the exhaust air must be HEPA filtered, to protect the environment
- Designed for general microbial research with low and moderate-risk agents
- The work zone, which type is much smaller than a chemical fume hood, is geared to working with biological whose process/ producers dictates the use of moderate amounts of volatile liquids, that are suitable for recirculation cabinets
