Checks to the area
5.1.2.1.
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.
5.1.3.
Work procedure
5.1.3.1.
Work shall be undertaken under a controlled procedure so as to minimise the risk of a flammable gas or vapour being present while
the work is being performed.
5.1.4.
General work area
5.1.4.1.
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.
5.1.5.
Checking for presence of refrigerant
5.1.5.1. 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.
5.1.6.
Presence of fire extinguisher
5.1.6.1.
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.
5.1.7.
No ignition sources
5.1.7.1. 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.
5.1.8.
Ventilated area
5.1.8.1. 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.
5.1.9.
Checks to the refrigerating equipment
5.1.9.1.
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.
