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
This document gives requirements and recommendations for installation, commissioning and routine
testing of BSC.

4 Installation of BSC
4.1 General
This clause gives recommendations and guidance on the installation of BSC, including siting and
connection to and interfacing with building ventilation and utility services.
4.2 Information required for installation of BSC
The following minimum information should be available for the installation. It is recommended that a site
survey should be carried out covering the following topics:
— cabinet size, weight, type and model;
— services/utilities to be fitted;
— dimensional clearances required for access to the final location;
— the location of the laboratory and the intended siting of the safety cabinet within the laboratory;
— details of the laboratory which might adversely affect the performance of the cabinet (location of
doors, windows, other ventilated devices that may cause draughts, air handling and air conditioning
systems, other air handling devices as well as other devices that generate temperature changes in
the laboratory);
— environmental operating conditions shall be considered (i.e. humidity, temperature ranges, heat
loading etc.);
— when ducted, requirements of the extraction system, i.e.:
— details about the connection (typically size, locations, thimble, hard duct, variable air volume
(vav)/constant air volume (cav)/constant volume regulator (cvr));
— settings resulting in variable exhaust air flows;
— exhaust air volume of BSC;
— data exchange between BSC and building management system;
— anti blow back;
— manufacturer instructions on installation;
— any other specific requirement.
4.3 Recommendations for siting of BSC class I and class II
4.3.1 General
The protective function of a BSC relies on a controlled inflow of air through the front aperture. Localized
air turbulence, temperature fluctuation, room layout, and large objects can affect the airflow performance
of BSC.
As a preliminary to the installation of BSC in a laboratory, the site should be surveyed by the BSC
manufacturer/installer to assess environmental conditions and positions of the BSC.
The survey should include a review of the possible positions for the BSC in relation to laboratory doors
and windows, the main routes of foot traffic and potential objects that can have an effect on the
performance of the BSC. Objects such as other BSC, work benches, walls and columns should all be taken
into consideration. In addition, other laboratory equipment should also be assessed and considered.
4.3.2 Impact of extract-, make-up and supply air systems
The impact of room air supplies and extracts including air-conditioning uni
