Compliance starts with knowing the right gas detection standards.

The AS/NZS 60079 series, Australia’s adoption of IEC 60079, covers explosion protection across a range of techniques, from intrinsic safety to flameproof enclosures, and is referenced for any gas detector used in a hazardous area. AS/NZS 60079.29.1 sets the performance requirements for flammable gas detectors, while AS/NZS 60079.29.2 covers how they’re selected, installed, used and maintained.

For toxic and oxygen detection, AS/NZS 4641 sets out the requirements. AS 2865 governs confined space entry, AS/NZS 1715 covers respiratory protection and breathing air quality, and AS 1668.2:2024 applies to mechanical ventilation, including carpark CO monitoring. AS 5034 covers carbon dioxide and inert gases in beverage cellars and cool rooms. Marine applications are governed by DNV standards for type approval and offshore fire and gas protection.

ISO 9001 underpins quality assurance across Gastech’s operations, and ISO/IEC 80079.34 applies to quality systems for the manufacture of explosion protected equipment.

Gastech supplies gas detection equipment that meets the relevant standards for your industry, whether you’re operating in mining, marine, food and beverage, chemical manufacturing or any other sector across Australia and internationally.
