Flammable Refrigerants Safety Guide - AIRAH

AIRAH strongly recommends that all refrigeration technicians be trained in the handling of flammable refrigerants.


The online Flammable Refrigerants Safety Guide (FRSG) has been produced by the Australian Institute of Refrigeration, Air Conditioning and Heating (AIRAH).

The free guide is designed to improve awareness of how to best manage the health and safety risks associated with the use and management of flammable refrigerants in stationary refrigeration and air conditioning equipment.

AIRAH would like to acknowledge support received from the Department of the Environment and Energy in developing this online training.

What it covers

Refrigeration technicians must have access to refrigeration classification standard AS/NZS ISO 817 and design standards AS/NZS 5149 (parts 1 to 4).

This online resource will help refrigeration technicians, apprentices and other stakeholders understand the range of skills and knowledge required to work safely with flammable refrigerants.

Designers, installers and service providers should access the AS/NZS 5149 Refrigerating systems and heat pumps – Safety and environmental requirements series in order to understand the precise requirements for an individual installation.

Please note: this does not substitute for the detailed, nationally-endorsed technical training which provides guidance on how to safely and productively work with flammable refrigerants. It is a guide meant to complement your training and improve awareness of best practices.
