to hand. Have a dry powder orCO2 fire extinguisher adjacent to the charging
area.
2.2.6 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.
2.2.7 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.
2.2.8 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
manufacturer’s technical department for assistance.
The following checks shall be applied to installations using flammable
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 operating adequately and are
not obstructed;
