Exhaust air is hepa filtered before leaving the safety cabinet via a single or double.
Microbiological safety cabinet class 1.
However should the main extract fan fail during cabinet operations the user is immediately alerted to the problem via an audible and visual alarm.
This page provides links to the home pages for three sites that contain information relating to microbiological safety.
Class 1 microbiological safety cabinets.
All class i biological safety cabinets are suitable for work with microbiological agents assigned to biosafety levels 1 2 and 3.
Normal cabinet operations are completely unaffected by the provision of a trimat exhaust module on the microbiological safety cabinet.
Class ii biological safety cabinets like class i safety cabinets class ii cabinets have a stream of inward air moving into.
Scope and application of class i cabinets is limited and it is largely considered obsolete.
Like class i cabinets class ii cabinets are safe for work using agents requiring biosafety level 1 2 or 3 containment.

A class ii type a1 cabinet must maintain a minimum average inflow velocity of 75 fpm through the sash opening.
Class 1 microbiological safety cabinets provide operator protection by means of a constant air inflow through the open front working aperture which prevents escape of airborne particulate contamination from the cabinet.
They may exhaust hepa filtered air back into the lab or may be exhaust outside using a canopy connection.
Class 3 microbiological safety cabinets provide total barrier protection for the operator and are suitable for extreme bio hazard work.
Class i microbiological safety cabinets bio 1 the envair bio 1 provides microbiological safety for the handling of biological agents up to and including acdp hazard group 3.
Class i microbiological safety cabinets bio 1 the envair bio 1 provides microbiological safety for the handling of biological agents up to and including acdp hazard group 3 subject to proper sitting operation and maintenance and has the following features.
Inflow air is hepa filtered before entering the class 3 biological safety cabinet via a side mounted inlet filter chamber.
They cover occupationally acquired infections the contained use of genetically modified organisms gmos and work with specified animal pathogens.
A biosafety cabinet bsc also called a biological safety cabinet or microbiological safety cabinet is an enclosed ventilated laboratory workspace for safely working with materials contaminated with or potentially contaminated with pathogens requiring a defined biosafety level several different types of bsc exist differentiated by the degree of biocontainment required.
