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.
i) 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: That capacitors are discharged: this shall
be done in a safe manner to avoid possibility of sparking; That there no live
electrical components and wiring are exposed while charging, recovering or
purging the system; That there is continuity of earth bonding.
23. REPAIRS TO SEALED COMPONENTS
a) 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
hazardous situation.
b) Particular attention shall be paid to the following to ensure that by working on
electrical components, the casing is not altered in such a way that the level of
protection is affected.
This shall include damage to cables, excessive number of connections,
terminals not made to original specification, damage to seals, incorrect fitting
of glands, etc.
Ensure that apparatus is mounted securely.
Ensure that seals or sealing materials have not degraded such that they no
longer serve the purpose of preventing the ingress of flammable atmospheres.
Replacement parts shall be in accordance with the manufacturer's
specifications.
The use of silicon sealant may inhibit the effectiveness of some types of
leak detection equipment. Intrinsically safe components do not have to be
isolated prior to working on them.
24. 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. Intrinsically safe components are the
only types that can be worked on while live in the presence of a flammable
atmosphere.
The test apparatus shall be at the correct rating.
Replace components only with parts specified by the manufacturer.
Other parts may result in the ignition of refrigerant in the atmosphere from a
leak.
