2-5. No ignition sources
• No person carrying out work in
relation to a refrigerating 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. He/She must not be
smoking when carrying out such
work.
• 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.
2-6. 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.
2-7. Checks to the refrigerating
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 actual refrigerant charge
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.
-Refrigerating 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 properly protected
against being so corroded.
