ENGLISH
- If an indirect cooling circuit is used, the secondary circuit must be checked for refrigerant
presence.
- Equipment marking remains visible and legible. Illegible markings and symbols should be
corrected.
- The components or refrigerant piping are installed in a position where they are not
susceptible to exposure to any substance that may corrode the refrigerant-containing
components, unless the components are made of materials that are inherently resistant
to corrosion or are properly protected against it.
1.9. Verification of electrical devices
Repair and maintenance of electrical components should include initial safety checks and
component inspection procedures. If there is a fault that may compromise safety, then no
power supply should be connected to the circuit until the fault is satisfactorily dealt with. If
the fault cannot be corrected immediately, but continued operation is necessary, a suitable
temporary solution must be used. This should be reported to the owner of the equipment so
as to inform all parties.
During initial safety checks, make sure:
- that capacitors are unloaded–this must be done in a safe manner to avoid sparks.
- that no live wiring or electrical components are exposed while loading, recovering, or
purging the system.
- that there is continuity in the earth connection.
2. Repair of sealed components
- During the repair of sealed components, all power supplies should be disconnected
from the equipment being worked on prior to any removal of sealed covers, etc. If it is
absolutely necessary to have a power supply to the equipment during service, then a
permanently operating form of leak detection should be placed at the most critical point
to warn of a potentially hazardous situation.
- Particular attention must be paid to the following to ensure that, when working on
electrical components, the housing is not altered in such a way as to affect safety. This
must include damage to cords, an excessive number of connections, terminals not
conforming to the initial specification, damage to seals, incorrect fitting of the stuffing
box, etc.
- Ensure that the instrumentation is securely mounted.
- Ensure that seals or sealing materials have not degraded until no longer being useful
to preventing the penetration of flammable atmospheres. Spare parts must be in
accordance with the manufacturer's specifications.
NOTE: the use of silicone sealant may inhibit the effectiveness of some types of leak-
detection equipment. Intrinsically safe components do not have to be isolated before work.
