Factors To Consider While Choosing A Biological Safety Cabinet

The Biological Safety Cabinet is designed to offer protection from particulates and

aerosolized pathogens to personnel, product and environmental protection. Weiber Biosafety Cabinets is an enclosed, ventilated laboratory workspace for safely working with materials contaminated with pathogens. Many factors should be kept in mind while selecting a Biological Safety Cabinet.

Selection Based on Agents Used Inside the Cabinet

The Biological safety cabinets are designed to provide protection against the various Risk group agents involving Group 1 Agents, Group 2 Group 3 and Group 4. The hazard group of the biological agents and hazardous aerosols to be handled in the cabinet.

Selection Based on Biosafety Cabinet Classification

Is the cabinet provides protection to operators or product or both required?

Bio safety Class I is suitable for work done with distinct and differentiated damages of microbial germs not recognized to cause infection in well mature persons. It symbolizes an essential level of control that relies on normal microbiological performance.

Biosafety Class II is suitable for handling moderate risk agents. Agents can be utilized carefully on the workstation, given the prospective for generating sprays or aerosols is low. Primary risks to personnel working with these agents recount to accidental external contacts or ingestion of communicable resources.

Biosafety Class III is appropriate to work finished with native agents with a potential for respiratory communication and which may cause stern and latently lethal harm. Larger emphasis is set on primary and secondary fences to guard personnel in adjacent areas, the community and the surroundings from coverage to communicable aerosols. For instance, all laboratory operations must be executed in bio logical safety cabinet.

Selection Based on Recirculation of Chemical Fumes

In addition to biological hazards, are radioisotopes, toxic chemicals or carcinogenic materials to be used inside the cabinet?

Selection based on Standard Specifications

The Biosafety Cabinet are made in accordance with the international industry standards such as British Standard BS5726, NSF-49, European Standard EN12469, Australian Standard AS2252 and AS2567. The Cabinet has acquired recognition from ISO and NABL and must be CE marked.

Based on Safety Features

The Cabinet offer security tools consist of biological security cabinets, surrounded containers and other tools to eliminate or reduce coverages to dangerous biological resources. The cabinet must have an airflow indicator with audible alarm for incorrect airflow fitted in a position where it is easily visible to the user of the cabinet.

Selection Based on Clean ability

Requirement of sufficient make-up air into the laboratory for the exhaust and check whether the current ventilation design is sufficient for this.
