 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 aected. This shall include
damage to cables, excessive number of connections, terminals not
made to original specication, damage to seals, incorrect tting of
glands, etc.
• Ensure that apparatus is mounted securely.
• Ensure that seals or sealing materials have not degraded in such
a way that they no longer serve the purpose of preventing the
ingress of ammable atmospheres. Replacement parts shall be in
accordance with the manufacturer s specications.
NOTE: The use of silicon sealant may inhibit the eectiveness
of some types of leak detection equipment. Intrinsically safe
components do not have to be isolated prior to working on them.
8. 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 ammable atmosphere. The test apparatus shall be
at the correct rating.
Replace components only with parts specied by the manufacturer.
Other parts may result in the ignition of refrigerant in the atmosphere
from a leak.

Check that cabling will not be subject to wear, corrosion, excessive
pressure, vibration, sharp edges or any other adverse environmental
eects. The check shall also take into account the eects of aging or
continual vibration from sources such as compressors or fans.
