With most manufacturers providing solid biological safety cabinets (BSCs), total cost of ownership has become a hot-button issue with purchasers. Until around 2000, exhaust fans were driven by AC permanent split capacitor motors. Manufacturers gradua

There are some emergencies that can’t wait five minutes for EMTs to arrive. Severe bleeding is one of these. A person can bleed to death in three to five minutes depending on the severity. Employees need to be available to deal effectively with this and other serious emergencies.

In the late 1970s and early 1980s, the increased availability and reduced cost of electronic air velocity sensors made sensor-based feedback loops a viable solution for biosafety cabinet manufacturers.

Biological safety cabinets should be decontaminated under the following conditions:

Biological safety cabinets should be decontaminated under the following conditions.

The modern Class II Microbiological Safety Cabinet, now regarded as probably the most common in-use Safety Cabinet employed around the world, is available with features meeting the stringent ergonomic and green requirements in many countries.

In order to maintain proper containment, NSF stipulates that recirculating and exhausted airfl ow volumes, and therefore velocities, must be maintained within a tolerance of +/- 5 feet per minute (FPM).

One of the characteristics of an effective safety program is the availability of reference and resource materials.
