No person carrying out work in relation to a refrigerating system which involves
exposing any pipe work shall use any sources of ignition that 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, repair, removal
and disposal, during which refrigerant might be released into the surrounding
space. Prior to starting work, the area around the equipment shall be surveyed to
make sure that there are no flammable hazards or ignition risks. "No Smoking"
