1.6 No ignition sources
No person carrying out work in relation to a refrigeration
system which involves exposing any pipe work that con-
tains 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, in-
cluding igarette 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.
1.7 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 ex-
pel it externally into the atmosphere.
1.8 Checks to the refrigeration 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 manu-
facturer's technical department for assistance.The follow-
ing checks shall be applied to installations using flamma-
ble refrigerants: the charge size is in accordance with the
room size within which the refrigerant containing parts are
installed; the ventilation machinery and outlets are oper-
ating adequately and are not obstructed; if an indirect re-
frigerating circuit is being used, the secondary circuit shall
be checked for the presence of refrigerant; marking to the
equipment continues to be visible and legible. Markings
and signs that
