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.
• 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.
• 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 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
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.
• Checks to electrical devices
Repair and maintenance to electrical components shall include
initial safety checks and component 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 operation, an adequate temporary
solution shall be used. This shall be reported to the owner of the
equipment so all parties are advised.
Initial safety checks shall include:
