10. Repairs to sealed components

During repairs to sealed components, all electrical supplies shall be disconnected from the

equipment being worked upon before any removal of sealed covers, etc. If it is 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, an excessive number of connections, terminals not

made to original specification, damage to seals, incorrect fitting of glands, etc.

• Ensure that the apparatus is mounted securely.

• Ensure that seals or sealing materials have not degraded to the point that they no

longer serve the purpose of preventing the ingress of flammable atmospheres.

Replacement parts shall be by the manufacturer’s specifications.

11. 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 currently permitted for the equipment

in use.

Intrinsically safe components are the only types that can be worked on while living 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.

12. Cabling

Check that cabling will not be subject to wear, corrosion, excessive pressure, vibration,

sharp edges, or any other adverse environmental effects. The check shall also consider the

effects of ageing or continual vibration from sources such as compressors or fans.

13. Detection of flammable refrigerants

Under no circumstances shall sources of ignition be used in the searching for or detection of

refrigerant leaks. A halide torch (or any other detector using a naked flame) shall not be

used.
