5. NO IG N ITI ON SOURCE S
• No person carrying out work in relation to a refrigerant 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 refrig-
erant 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.
6. V E NTI L ATE D AREA
• Ensure that the area is in the open or that it is adequately ventilated before breaking into
