1.6 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.
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 expel it externally into the
atmosphere.
