precautions shall be complied with prior to conducting work on the
system.
2.2.2 Work Procedure
Work shall be undertaken under a controlled procedure so as to
minimize the risk of a flammable gas or vapor being present while the

2.2.3 General Work Area
All maintenance staff and others working in the local area shall be
instructed on the nature of work being carried out. Work in confined
spaces shall be avoided. The area around the workspace shall be

made safe by control of flammable material.
2.2.4 Checking for Presence of Refrigerant
The area shall be checked with an appropriate refrigerant detector prior
to and during work, to ensure the technician is aware of potentially
flammable atmospheres. Ensure that the leak detection equipment
being used is suitable for use with flammable refrigerants, i.e. no
sparking, adequately sealed or intrinsically safe.
