Instruction, Repairing Appliances Containing R290
1. Checks to the area
Prior to beginning work on systems containing flammable refrigerants, safety
checks are necessary to ensure that the risk of ignition is minimised. For repair to
the refrigerating system, the following precaution shall be completed prior to
conducting work on the system.
2.
Work procedure
Work shall be undertaken under a controlled procedure to minimise the risk of a
flammable gas or vapour being present while the work is being performed.
3. General work area
All maintenance staff and others working in the local area shall be instructed on
the nature of work being carried out. Work in confined spaces shall be avoided.
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.
