Introduction

The adoption of refrigerants with low Global Warming Potential, in response to concerns about the

effect of some fluorocarbons on climate, has raised the profile of fluids which were previously limited in

their use due to flammability. As the industry moves towards greater use of low GWP flammable

refrigerants, in particular from flammability class A3, it is important to ensure that installation methods

also change to support this technology transition.

The purpose of this document is to provide information to ensure acceptable risk levels applying

flammable refrigerants.

This document therefore provides technical information to the companies and individuals directly

involved in activities at the worksite; the owner of the system and the company and individuals that

install equipment.
