4) Checking for presence of refrigerant
The area shall be checked with an appropriate refrigerating detector prior to and
during work, to ensure the technician is aware of potentially flammable
atmospheres. Ensure that the leak detection equipment being used is suitable for
use with flammable 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 refrigeration 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 that contains
or has contained flammable refrigerant
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,
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 refrigerating equipment
Where electrical components are being changed, they shall be fit for the purpose
and to the correct specifications. At all ti
mes 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 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 unit
continues to be visible and legible. markings and signs that are illegible shall be
corrected; and refrigerating pipe or components are installed in a position where
they are unlikely to be exposed to any substance which may corr
ode 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.
