AS/NZS 2430.3.6:2004 — Classification of hazardous areas, Part 3.6: Examples of area classification — Laboratories, including fume cupboards and flammable medical agents. Reissued incorporating Amendment No. 1 (2007). This part gives guidance and worked examples for classifying laboratory spaces, fume cupboards and areas where flammable medical agents are used, and is intended to be read in conjunction with AS/NZS 2430.3.1.

Abstract

This short, example-based part of the AS/NZS 2430.3 series provides specific area-classification examples for laboratories, fume cupboards and storage/use of flammable medical agents. It explains typical arrangements, identifies where hazardous atmospheres may occur and shows how to apply the zone/classification principles in those situations. The document supplements the general guidance in AS/NZS 2430.3.1.

Scope

This part provides examples of area classification for laboratory environments and fume cupboards and for the storage and use of flammable medical agents. It gives worked examples and classification recommendations for typical laboratory arrangements, types of fume cupboards (including those complying with AS/NZS 2243.8), storage locations and anaesthetizing areas. It is intended to be used together with the general examples and principles in AS/NZS 2430.3.1.

Key topics and requirements

• Examples and classification guidance for storage of flammable medical agents and associated storage areas.
• Classification guidance for anaesthetizing areas and locations where volatile anaesthetics are used.
• Examples for fume cupboards that comply with AS/NZS 2243.8 and for other fume cupboards not complying with that standard.
• Worked examples for laboratory layouts and the resulting area classifications (including figures illustrating typical zones/areas).
• Definitions, referenced documents and normative references needed to apply the examples in practice.

These topics and clause headings are representative of the table of contents and amendment history for the part.

Typical use and users

Used by safety engineers, facility managers, laboratory managers, hospital estates/facilities teams, consulting engineers, hazardous area classification specialists and electrical installers when assessing and documenting hazardous-area zones in laboratories, medical facilities and locations containing fume cupboards or flammable medical agents. Practitioners use it alongside the general AS/NZS 2430.3.1 guidance and other electrical/explosion-protection standards when selecting equipment and specifying safe installation practices.

FAQ

Q: What is this standard?

A: AS/NZS 2430.3.6:2004 is a short example-based part of the AS/NZS 2430.3 series that gives worked examples and guidance for classifying hazardous areas specifically in laboratories, fume cupboards and locations where flammable medical agents are stored or used.

Q: What does it cover?

A: It covers how to identify and classify areas in typical laboratory arrangements, how to treat fume cupboards (both those meeting AS/NZS 2243.8 and others), storage of flammable medical agents and anaesthetizing areas, with illustrative examples to apply the area classification principles.

Q: Who typically uses it?

A: Safety and compliance professionals, consulting engineers, laboratory and hospital facilities managers, hazardous-area assessors and electrical contractors use it when performing hazardous-area classification and when preparing specifications for equipment and installations in laboratory or medical settings.

Q: Is it current or superseded?

A: It is superseded. The guidance in the AS/NZS 2430.3.x series (including part 3.6) has since been consolidated into and superseded by the AS/NZS 60079.10.x series (for example AS/NZS 60079.10.1:2009 and later revisions); check the national standards catalogue for the exact supersession and revision history for your jurisdiction.

Q: Is it part of a series?

A: Yes — it is one part of the AS/NZS 2430.3 collection of example-based parts (the 2430.3.x series) that provide examples for a range of environments; it is intended to be read in conjunction with AS/NZS 2430.3.1 (General).

Q: What are the key keywords?

A: Hazardous area classification, laboratories, fume cupboards, flammable medical agents, AS/NZS 2430.3.6, area examples, zone classification, amendment 2007.
