4) Verify the absence of operating voltage: always test before you touch!
Only use properly rated and inspected voltage detection devices and wear
proper PPE identified in step 1:
• Test voltage detection device
• Test for voltage
• Test voltage detection device
It is highly important that the voltage detection device is tested on a known
voltage source such as a Proving Unit or by performing an internal self-test,
according to the manufacturer’s instructions, before and after testing for the
absence of operating voltage.
5) Carry out earthing and short-circuiting.
• Close and lock the earthing switch if the electrical equipment is designed
for this purpose or apply portable equipment for earthing and short-
circuiting.
If this is carried out by the customer, then the PICW must ensure that this
equipment is properly earthed as a part of the integration/verification and
during step 7 when the PICW walks the PTW.
6) Protect against adjacent live parts and take special precautions when close
to bare conductors.
• Determine minimum approach distances, apply screening or shrouding,
and when applicable, padlock both cable and busbar shutters.
• If working within the restricted approach boundary or vicinity zone where
inadvertent movement could cause contact with live parts, special
precautions must be employed, such as the use of the properly rated
insulated gloves and tools.
7) Complete the permit to work and “Walk the Permit”.
• Check isolation points
• Verify that all circuits are isolated and secured
• Ensure all parties are integrated with the Lockout/Tagout
• Check the earths are properly applied
• Answer specific questions from the working group
• Ensure the work can proceed without danger
• Complete and verify the “Permit to Work”
