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: 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.
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 hazardous
situation. 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
