hazards or ignition risks. “No Smoking” signs shall be displayed.
6. 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 wok. 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.
7. Checks to the refrigeration equipment
• Where electrical components are being changed, they shall be
fit for the purpose and to the correct specification. 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 flammable
refrigerants:
The charge size 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 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.
8. Checks to electrical devices
• Repair and maintenance to electrical components shall include initial
safety checks and components inspection procedures. If a fault
exists that could compromise safety, then no electrical supply shall
be connected to the circuit until it is satisfactorily dealt with. If the
fault cannot be corrected immediately but it is necessary to continue
