Permits to Work
Nobody opens a panel, lights a torch or enters a tank without one: what is being done, what could go wrong, what has been done about that, and two signatures with a start and an end time.

The permit
A permit with no end is a permit nobody ever closes.
Where and who
Only firms approved to work are listed. If the one you want is missing, their papers are the thing to fix — not this field.
The person who stays there while the work is going on.
The work and the risk
Isolation, barriers, extinguishers, gas testing, a standby person. Name them, do not promise them.
Oxygen, flammables and toxics, with the time it was taken.
