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 flammable 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 no flammable hazards or ignition risks.
"No Smoking" signs shall be displayed.
2.4.7. Ventilated area
Ensure that the area is in the open or that it is adequately
ventilated before breaking into the system or conducting any hot
work. A degree of ventilation shall continue during the period that
the work is carried out. The ventilation should safely disperse any
released refrigerant and preferably expel it externally into the
atmosphere.
2.4.8. Checks to the refrigeration equipment
Where electrical components are being changed, they shall be fit
for the purpose and to the correct specification. At all times the
manufacturer's maintenance and service guidelines shall be
followed. If in doubt consult the manufacturer's technical
department for assistance.
The following checks shall be applied to installations using
flammable refrigerants:
• The charge size is in accordance with the room size within which
the refrigerant containing parts are installed;
• The ventilation machinery and outlets are operating adequately
and are not obstructed;
• If an indirect refrigerating circuit is being used, the secondary
circuit shall be checked for the presence of refrigerant;
• Marking to the equipment continues to be visible and legible.
Markings and signs that are illegible shall be corrected;
• Refrigeration pipe or components are installed in a position where
they are unlikely to be exposed to any substance which may
corrode refrigerant containing components, unless the
components are constructed of materials which are inherently
resistant to being corroded or are suitably protected against being
so corroded.
