d) Checking for presence of refrigerant
The area shall be checked with an appropriate refrigerant detector prior to
atmospheres.
Ensure that the leak detection equipment being used is suitable for use with
safe.
If any hot work is to be conducted on the refrigeration equipment or any
at hand.
f) No ignition sources
No person carrying out work in relation to a refrigeration system which involves
shall use any sources of ignition in such a manner that it may lead to the risk
All possible ignition sources, including cigarette smoking, should be kept
surrounding space.
Prior to work taking place, the area around the equipment is to be surveyed to
signs shall be displayed.
g) 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.
h) Checks to the refrigeration equipment
At all times the manufacturer’s maintenance and service guidelines shall be
followed.
If in doubt consult the manufacturer’s technical department for assistance.
refrigerants:
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 circuit shall be checked for the presence of
refrigerant; Marking to the equipment continues to be visible and legible.
Markings and signs that are illegible shall be corrected; Refrigeration pipe or
components are installed in a position where they are unlikely to be exposed to
any substance which may corrode refrigerant containing components, unless
the components are constructed of materials which are inherently resistant to
being corroded or are suitably protected against being so corroded.
