Safety 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 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 refrigeration 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, should be
kept sufficiently far away from the site of installation, repairing,
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
