Introduction
Biological safety cabinets (BSC) are designed to reduce the risk to the operator when using biological
materials. Dependent on type, they can protect the operator, the product, and the environment from
biological aerosols.
BSC class I and class II are ventilated enclosures with an open front aperture.
A BSC class III is a fully enclosed workspace with gloves attached to the front port normally with an
additional pass-through box attached.
A BSC class I provides operator and environment protection.
A BSC class II provides operator, product, and environment protection. In addition, it offers cross-
contamination protection.
A BSC class III provides operator, environment and product protection. It is normally used in high level
containment facilities for the highest risk group agents.
The type of BSC required is usually based on risk group, risk assessment and application.
This document describes the design and testing of these BSC for use in laboratories handling biological
agents.
This document is a product standard. Occupational health and safety assessments methods are not
included.
1 Scope

safety and hygiene.
It sets the specific performance criteria for class II BSC for work with biological agents and specifies test
procedures with respect to protection of the worker, the environment and product protection including
cross-contamination.
