Requested from site
An operative requests a permit from their phone, choosing the type, the task and the area. The request goes straight to the people you have chosen for that job, and their page shows "Waiting, do not start" until it is approved.
Approved by a named person
The site manager or office reviews the request, sets the controls, the time window and who it covers, and approves or refuses it. Everyone named on the permit is sent a link to read it.
Signed on site before work starts
Each named person reads the permit and its controls and signs it on their phone, but only once they have signed in at the site door that day. The permit can be signed with no signal and is recorded as soon as the phone reconnects.
Closed when the work is done
When the work is finished, the permit is closed from the operative's page or the office, with the time and who closed it. A closed permit cannot be reused, and every permit is kept as PDF evidence.
