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.
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.
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.
9)Checks to electrical devices
Repair and maintenance to electrical components shall
include initial safety checks and component inspection
procedures. If a fault exists that could compromise safety,
then no electrical supply shall be connected to the circuit
until it is satisfactorily dealt with. If the fault cannot be
corrected immediately but it is necessary to continue
operation, an adequate temporary solution shall be used.
This shall be reported to the owner of the equipment so
all parties are advised.
Initial safety checks shall include:
That capacitors are discharged: this shall be done in a
safe manner to avoid possibility of sparking;
That there no live electrical components and wiring are
