No person carrying out work in relation to a refrigeration system which involves exposing any pipe
Prior to work taking place, the area around the equipment is to be surveyed to make sure that there
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.

--If an indirect refrigerating circuit is being used, the secondary circuit shall be checked for the
presence of any refrigerant. Any markings to the equipment must be visible and readable .
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.
--that capacitors are discharged; this shall be done in a safe manner to avoid possibility of sparking;
--that there no live electrical components and wring are exposed while charging, recovering or
purging the system;
--that there is continuity of earth bonding.
7. Repairs to sealed components
During repairs to sealed components, all electrical supplies shall be disconnected from the
equipment being worked upon prior to any removal of sealed covers, etc. If it is absolutely
necessary to have an electrical supply to equipment during servicing, then a permanently
operating form of leak detection shall be located at the most critical point to warn of a potentially
Particular attention shall be paid to the following to ensure that by working in electrical

equipment. Intrinsically safe components do not have to be isolated prior to working on them.
8. Repair to intrinsically safe components
Do not apply any permanent inductive or capacitance loads to the circuit without ensuring that
this will not exceed the permissible voltage and current permitted for the equipment in use.
Check that cabling will not be subject to wear, corrosion, excessive pressure, vibration, sharp
