IMPORTANT INSTRUCTIONS
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 toxic or flammable atmospheres. Ensure that the leak detection equipment
being used is suitable for use with all applicable 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 refrigerating 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 REFRIGERATING SYSTEM which involves exposing any pipe
work 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 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 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
Ÿ
containing parts are installed;
Ÿ the ventilation machinery and outlets are operating adequately and are not obstructed;
Ÿ 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
Ÿ
corrected;
refrigerating pipe or components are installed in a position where they are unlikely to be exposed to any
Ÿ
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.
