Digital permit to work: what it is and how to roll it out

What a permit to work is, which Brazilian standards require it and how to move from paper to a system with checklists, signatures, revalidation and audit.

Quick answer

A permit to work is the document that authorizes a hazardous activity after safety conditions have been checked. In digital form, the requester picks the type of activity, answers the matching checklist, participants sign on screen and the system controls validity, revalidation and closure.

At port bases, on vessels and in industrial plants, many activities can only start with a signed permit to work. When that control is done on paper, the form becomes the bottleneck. This article explains what a permit to work has to guarantee and how a system helps.

What is a permit to work?

A permit to work is a formal document that authorizes a hazardous activity, in a defined place and period, after safety conditions have been checked. It describes the job, the risks, the control measures and who authorized it.

The UK safety regulator, the HSE, defines a permit-to-work system as a formal written system used to control certain types of work that are potentially hazardous. The permit does not make the activity safe by itself. It records that someone checked the conditions and took responsibility for the authorization.

Which Brazilian standards require a permit to work?

Several regulatory standards (NRs) from Brazil's Ministry of Labor and Employment deal with the subject. These are the ones most cited in port and offshore operations.

StandardSubjectHow the permit appears
NR-33Confined spacesEntry and Work Permit before entry
NR-35Work at heightPermit to Work for non-routine activities
NR-34Shipbuilding and repairPermit to Work for hot work and other activities
NR-20Flammables and fuelsPermit for interventions with ignition risk

This summary is general guidance. The text of each standard changes over time, and the person who defines what applies to your operation is the company's occupational safety lead. Always check the version in force on the Ministry's website.

What are the problems with paper?

Paper fails where time matters. These are the most common problems.

  • The form travels around the base collecting signatures while the job waits.
  • Nobody knows, at a given moment, how many permits are open and where.
  • Revalidation from one shift to the next depends on someone remembering.
  • The checklist is generic, the same for activities with different risks.
  • An audit means searching folders, and an illegible permit becomes a doubt.

In the port operations case we published, those were exactly the symptoms before the system.

What does a permit to work system need to do?

It needs to reproduce the paper control and add what paper cannot do. These are the essential functions.

  1. Activity types with their own checklist. The requester picks the nature of the activity, and the system shows the checks for that type.
  2. Participants and signatures. Requester, workers and issuer sign on screen, with date and time recorded.
  3. Validity and revalidation. The permit has a time limit, and continuing on another shift requires a new recorded check.
  4. Closure. The job ends with a record that the area was left in a safe condition.
  5. A board of open permits. One screen shows what is in progress, by location.
  6. Audit. Each permit keeps the history of who did what, and field audits are linked to it.

One technical point matters more than it seems. The rules for who can issue, approve or close have to be checked on the server, and not just hidden on screen. We explain that care in support and modernization.

How do you roll out a digital permit to work?

In steps, starting with one area.

  1. Map the current form. List the fields, the activity types and who signs each one. The paper that already exists is the best starting point.
  2. Pick a pilot area. A workshop or a quay, with a crew willing to test.
  3. Run in parallel for a short time. Paper and system together, only until the crew trusts the system.
  4. Expand and switch off paper. Area by area, with checklists reviewed by the safety department.

The system has to work on a phone, because the permit is issued where the work happens. Ours run as an app installed from the browser. See how that differs from a store app in apps.

Is a digital permit valid as a document?

The form of record is a decision for the company with its safety department and, where needed, its legal team. What the system offers is traceability: who signed, when, with which user and from which device. That record is usually easier to audit than a signature on paper.

We do not give legal advice on regulatory standards. We build the system from the procedure your company defines, as in any custom web system project.

Frequently asked questions about digital permits to work

Are a permit to work and a risk assessment the same thing?

No. The risk assessment identifies the hazards of the task and the control measures. The permit to work authorizes the job after those measures have been checked. In many procedures, the assessment is a mandatory attachment to the permit.

Does the system work in an area with no signal?

It depends on the design. An app installed from the browser stores the interface on the device, and the project defines which data is available offline and how it syncs later. In areas with no signal at all, that has to be planned from the start.

Can it integrate with access control and training records?

Yes, and that is one of the biggest gains. When the permit checks the training registry, the system prevents a worker with expired training from being added.

Can contractors request a permit?

Yes, with access limited to their own workers and requests. Issuing and approval stay with the hiring company's team.

How long does rollout take?

The schedule depends on the number of activity types and on how many areas join the pilot. Starting with a single activity type in a single area puts the system into use sooner.
