No person carrying out work with a refrigeration system which involves
exposing any pipe work that contains or has contained ammable
refrigerant shall use any sources of ignition in such a manner that
it may lead to risk of re or explosion. All possible ignition sources,
including cigarette smoking, should be kept suiciently far away from
the site of installation, repairing, removing and disposal, during which
ammable 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 ammable hazards or
ignition risks. “NO SMOKING” signs shall be displayed.
Ensure the work 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.
Where electrical components are being changed, they shall be t
for the purpose and to the correct specication. 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
ammable 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;
• If an indirect refrigerating circuit is being used, the secondary circuits
shall be checked for the presence of refrigerant; marking to the
equipment continues to be visible and legible.
