Safety instructions
9) 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:
• T hat capacitors are discharged: this shall be done in a safe manner
to avoid possibility of sparking;
• T hat there no live electrical components and wiring are exposed
while charging, recovering or purging the system;
• T hat there is continuity of earth bonding.
2. Repairs to sealed components
1) 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 isabsolutely 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.
2) 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.
