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
sectioned off. Ensure that the conditions within the area have been
made safe by control of flammable material.
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. non-sparking, adequately sealed or intrinsically safe.
5) Presence of fire extinguisher
If any hot work is to be conducted on the refrigeration equipment or
any associated parts, appropriate fire extinguishing equipment shall
be available to hand. Have a dry powder or CO2 fire extinguisher
adjacent to the charging area.
6) No ignition sources
No person carrying out work in relation to a refrigeration system
which involves exposing any pipe work that contains or has
contained flammable refrigerant shall use any sources of ignition in
such a manner that it may lead to the risk of fire or explosion. All
possible ignition sources, including cigarette smoking, should be
kept sufficiently far away from the site of installation, repairing,
removing and disposal, during which lammable refrigerant can
possibly be released to the surrounding space. Prior to work taking
place, the area
around the equipment is to be surveyed to make sure that there are
