Safety instructions
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 purpose of preventing the ingress of
flammable atmospheres. Replacement parts shall be in accordance
with the manufacturer's specifications.
Note: The use of silicon sealant may inhibit the
effectiveness of some types of leak detection equipment.
C
Intrinsically safe components do not have to be isolated
prior to working on them.
3. 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 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.
4. Cabling
Check that cabling will not be subject to wear, corrosion, excessive
pressure, vibration, sharp edges or any other adverse environmental
