One workplace fire in three originates from hot work operations (source: INRS, ED 6030). Welding, grinding, oxy-fuel cutting: seemingly routine operations whose risk is real and well documented. The permis feu (hot work permit) exists precisely to frame these interventions. The problem is that training the right people, at the right time, across several sites and with external partner contractors, is often an organisational headache. This article gives HSE and safety managers the keys to structure this system over the long term.
What is a permis feu and why is it essential?
The permis feu is a safety document to be drawn up before any hot work intervention carried out outside a permanent workstation. Its purpose: to formalise the preliminary risk analysis and define the preventive measures to apply before, during and after the intervention. It is not just another administrative form, it is the tool that forces the right questions to be asked before lighting the blowtorch.
The hot work operations concerned
'Hot work' refers to any operation likely to generate sparks, flames or hot surfaces capable of igniting combustible materials nearby. The scope is broader than is often assumed, including on routine maintenance sites. Portable rotating machines such as angle grinders and cut-off saws are a source of fires that is often underestimated. Only permanent fitted workstations, whose fire risk is already integrated into the workstation risk assessment, are excluded from the scheme.
To recap:
- Arc welding, oxy-fuel cutting, brazing
- Grinding, deburring, cutting
- Use of a blowtorch or hot bitumen
- Portable rotating machines: angle grinders, cut-off saws, drills
Some configurations combine the hazards. Hot work carried out in a confined space also falls under CATEC training, and an intervention at height requires dedicated work-at-height training.
The regulatory framework in France
The French Labour Code does not use the term 'permis feu', and that is important to know in this context. It is the general obligation to prevent risks (article L.4121-1), the fire prevention measures (article R.4227-28) and the obligations relating to outside contractors (article R.4512-7) that make it essential in practice. The order of 19 March 1993 sets out the obligations relating to the prevention plan (plan de prévention) for dangerous work carried out by outside contractors. For establishments subject to ICPE (classified installations) or ERP (public access buildings) regulations, the permis feu becomes explicitly mandatory. The INRS brochure ED 6030 is the operational reference.
To go further on the legal framework, you can consult the guide on mandatory training in companies.
Who must be trained on the permis feu in your company?
This is the question that many HSE managers handle too quickly. Training on the permis feu is often thought of as a single block for an undifferentiated audience, whereas three distinct profiles are involved, with radically different needs. Training on the permis feu is part of a broader approach to occupational risk prevention.
The case of outside contractors deserves particular attention. When a partner contractor intervenes on site, the co-signing of the document implies shared responsibility. Training only your own teams without ensuring the competence of external operators means taking a real regulatory and operational risk in any context.
What does an effective permis feu training contain?
The essential theoretical foundation
The theoretical part lays the foundations without which no permis feu will be correctly drawn up or applied. It covers several areas:
- understanding the fire triangle and the means of extinction,
- identifying the risks linked to hot work (explosive atmospheres, nearby combustible materials, propagation by conduction),
- the regulatory content of the document with its mandatory entries,
- articulation with the prevention plan and the DUERP,
- evacuation instructions in the event of an outbreak of fire.
The signatory must also master the notions of explosimetry and know the flammability limits of the products present on the site, competencies close to those worked on in chemical risk training.
Hands-on practice in the field
The practical part is essential and cannot be removed. It includes:
- exercises to draw up a permis feu from concrete cases,
- inspection of a zone before work,
- handling of EPI (PPE) and extinguishers with the participants,
- organisation of a post-intervention fire watch.
The presence on site of staff trained in first aid, through SST training (workplace first responders), strengthens the capacity for immediate response in the event of an outbreak of fire.

In person, e-learning or blended: which format to train on the permis feu?
Why digitise the theoretical component
Handling extinguishers and field exercises require an in-person group session. Everything else (regulations, the fire triangle, risk identification, the technical procedure for drawing up the document) digitises very well, with concrete advantages: onboarding new arrivals without waiting for the next inter-company or in-house session, simplified updates when regulations change, automatic traceability of certificates for audits.
For multi-site companies or those working with partner contractors, this is a powerful lever for standardisation. Adaptive learning also makes it possible to finely personalise the pathway according to the profile: the signatory does not have the same pedagogical needs as the operator or the fire watcher, and each one thus spends time on the topics that genuinely concern them.
Sustaining the embedding of practices over time
This is the point that classic training providers never address: what happens between two refresher sessions, in the absence of a follow-up policy? The research in cognitive science is clear. The spacing effect (Cepeda et al., 2006) and the testing effect (Roediger & Karpicke, 2006) show that spaced reminders and periodic verification quizzes significantly improve long-term retention. For safety training whose reflexes can save lives, this is an issue that deserves your full attention.

How to organise the follow-up and renewal of the training
Steering compliance across the company
Training once is not enough. The real challenge for an HSE manager is to know at all times who is trained, who is no longer trained, and how to prove it in the event of an inspection or accident. Putting structured follow-up in place is as important as the programme itself, and it starts with a renewal calendar available to all the employees concerned.
An LMS makes it possible to centralise certificates, automate alerts and produce audit reports in a few clicks. For multi-site groups or those with numerous partner contractors, it is the only realistic solution to guarantee safety and maintain consistent compliance.
This steering logic applies to your entire safety catalogue, from PRAP IBC training to posture and movement training, including MSD (TMS) training.
Read this article on training evaluation to structure this steering.
Checklist: the 5 traceability elements to maintain for each trained employee:
- Individual training certificate
- Date of the last training and profile trained (signatory, operator or fire watcher)
- Pedagogical assessment results
- Date of the next refresher in the calendar
- Status against training objectives (up to date / to be scheduled / overdue)
Conclusion
Permis feu training does not boil down to ticking a regulatory box. It is a concrete prevention programme, whose effectiveness depends as much on the pedagogical content as on the organisation built around it. Training the three profiles concerned, choosing the right methods according to the situation, ensuring follow-up over time: that is the real work of the HSE manager.
Guaranteeing the safety of teams in the face of fire risk starts with a structured, traceable and renewed system, not with a half-day forgotten six months later. This is precisely what a learning platform designed for genuine skills development makes it possible to put in place.
