1.1.5 Checking for presence of refrigerant. T
he
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.
1.1.6 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
at hand.
Have a dry powder or CO2 fire extinguisher adjacent to the charging
area.
1.1.7 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.
1.1.8 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. T
he
ventilation
should
safely
disperse
any
released
refrigerant
and
preferably
expel it externally into the atmosphere.
1.1.9 Checks to the refrigeration equipment. Where electrical
components are being changed, they shall be fit for the purpose and
