Permits to work

A permit to work is a formal, temporary and traceable authorisation: it allows a person or a team to carry out a specific activity, in a given place, for a precise window of time.

It is central to operational safety in high-risk work — hot work, confined spaces, electrical work, work at height — in complex industrial environments, and on sites where several contractors operate at once. In those settings safety is not being compliant: it is being authorised right now. That is the question a permit answers.

In 4HSE it is not a separate object

A permit to work is a certificate, issued at the end of a procedure, enriched with what an operational authorisation needs. 4HSE builds it out of things you already use, without introducing a parallel flow.

A certificate acting as a permit carries:

• the type of activity authorised;
• the place — site, area;
• the worker or the team authorised;
• the start and end of validity, to the hour if needed;
• a status;
• the completed forms — checklists, authorisations, assessments — which become part of it.

What it is made of

The permit runs across features documented elsewhere. This is the chain:

Piece	Role	Where
Procedure	defines what is being authorised	Procedures
Linked forms	the checks to complete, marked as required	Configure a form on an action
Certificate	the authorisation itself	Issue a certificate
Scheduler	where it is issued from and monitored	Scheduler and notifications
Public page	where anyone can verify it	Public verification

The required flag on a form is the mechanism that makes the whole thing work: the certificate cannot be created until those forms have been completed. Without it, a permit would be a certificate with a nice name.

What makes it different from a paper permit

A paper permit says it was valid when it was printed. A permit in 4HSE recalculates its status every time someone looks at it: scanning its QR code answers the only question that matters on site — is this permit valid right now?
