16 Maintenance notice
2. 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.
3. 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 CO
extinguisher adjacent to the charging area.
4. No ignition sources:
No person carrying out work in relation to a refrigeration 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.
5. Ventilated area (open the door and window):
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.
6. 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.
• 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.
