Hot Work Permit: Complete 2026 Guide

A welder has no right to strike an arc at a temporary workplace without a hot work permit. Period. Now the bad news: based on experience from inspections at oil refineries, construction sites and power facilities, roughly 70% of these documents contain errors. The most common issue is a vague description of the location. "Plant territory" instead of a specific workshop, elevation and column grid reference.

The penalty for failing to issue a permit: up to 400,000 roubles for a legal entity under Part 1 of Article 20.4 of the Code of the Russian Federation on Administrative Offences (hereinafter — the Code of Administrative Offences). If a fire breaks out, the amount grows to 800,000 roubles. Or a criminal case is opened.

This guide covers everything an occupational safety specialist, engineer or shop supervisor needs to know: which operations require a permit, who signs it, how to fill in the form correctly, how long to keep the document, and what liability applies for violations. A general reference on all permit types is available on the main page.

What a hot work permit is and why it matters

A hot work permit is, in essence, a written task authorisation from a manager. The document records: where exactly welding or cutting will be performed, at what time, with what equipment, who is responsible for preparing the site, who supervises the process, and what protective measures are mandatory.

The primary legal framework: the Fire Safety Rules of the Russian Federation, approved by Government Decree No. 1479 dated 16 September 2020 (hereinafter — the Fire Safety Rules). The document is in force until 31 December 2026. The latest amendments were introduced by Government Decree No. 90 dated 3 February 2025 and came into effect on 1 September 2025.

At hazardous industrial facilities (hereinafter — HIF), Rostechnadzor Order No. 528 dated 15 December 2020 applies in parallel. It approved the Federal Rules "Safe Conduct of Gas-Hazardous, Hot and Repair Work" (hereinafter — Order 528). A recommended form template is contained in Annex 4 to this order.

Three functions of the document

A formality? No. Electric welding and gas cutting are consistently among the top three causes of industrial fires in Russia. Annual statistics from the Russian Ministry of Emergency Situations confirm: thousands of fires are linked to violations during fire-hazardous operations. A properly issued document reduces the probability of a fire and, in case of an incident, protects the employer legally.

Which operations count as hot work: full list

Clause 372 of the Fire Safety Rules classifies as hot work all operations in which an open flame, electric arc, spark stream or heating of materials to ignition temperature occurs.

Reference table for specialists issuing the permit:

The list is open. The employer supplements it with a local order. In practice, oil-and-gas enterprises add open-flame pipe heating, while shipyards include burning off old paint in tanks and compartments.

The angle grinder deserves a separate mention. The AG is arguably the most underestimated item on this list. Many engineers simply do not realise that cutting metal with an angle grinder is legally equivalent to hot work. A stream of sparks from an abrasive disc flies up to 5 metres. Spark temperatures reach 1500 °C. That is enough to ignite rags, oil-soaked overalls or thermal insulation. At one site sparks from an AG burned through polyethylene film covering equipment. No hot work permit had been issued. The fine was 320,000 roubles.

When a permit is required — and when it is not

The main criterion is simple: a hot work permit is issued for welding, cutting and brazing at temporary workplaces. This is established by clause 372 of the Fire Safety Rules.

What qualifies as a stationary post

A stationary post is an area that:

• is included in the organisation list by order of the manager,
• is equipped with local exhaust ventilation (capacity no less than 1500 m³/h per torch),
• is equipped with primary fire-extinguishing means.

Everything else counts as a temporary workplace. And it requires a permit.

Typical mistake in practice

A characteristic case: a plant equipped a repair area with two welding tables. No exhaust ventilation was installed, the area was not added to the list of stationary posts. Result: the State Fire Supervision (hereinafter — SFS) inspector recorded welding at a temporary workplace without a permit. The fine under Part 1 of Article 20.4 of the Code of Administrative Offences was 300,000 roubles.

Fire-hazardous operations are simultaneously included in the list of high-hazard work under Order of the Ministry of Labour No. 776n dated 29 October 2021 (Annex 2). This means additional obligations: a project of work execution (hereinafter — PWE), occupational risk assessment and a targeted briefing.

Who issues and signs a hot work permit

Roles and duties differ depending on the category of the facility.

Ordinary facilities (Fire Safety Rules)

Hazardous industrial facilities (Order 528)

Contractors

Under contractor relationships, the document is issued by the contractor. The client issues an admission act and agrees on protective measures in its territory. A common situation: the contractor and the client confuse areas of responsibility. It is important to remember - the details of the admission act and PWE are always included in the form.

The form: structure, filling, typical mistakes

There is currently no single approved form for all organisations. The form from Annex 4 to Government Decree No. 390 lost legal force on 1 January 2021. A company develops its own template, includes the details from clause 372 of the Fire Safety Rules and approves it by order. For HIF, a template is provided in Annex 4 to Order 528.

Form structure

Electronic format

Clause 78 of Order 528 allows documentation to be maintained in electronic form with a qualified enhanced electronic signature (hereinafter — QEES). Implementation practice shows: the digital format solves three problems at once. Approval is faster, re-writing errors are eliminated, deadlines are tracked automatically. At enterprises that have switched to electronic systems, issuance time drops from 40 to 10-15 minutes.

What the inspector checks first

The "Protective measures" section. That is the first thing the SFS inspector will open. Wording must contain specific figures: type and number of extinguishers, distance from the welding point, clearance area in metres, fire-blanket specification. Vague phrasing is grounds for a report.

The five most frequent mistakes

Experience from industrial-safety inspections reveals typical filling violations:

Templates: "Permit Templates: All 2026 Forms". Issuance algorithm: "Permit Issuance: Step-by-Step 2026 Guide».

Procedure: preparation, execution, closing

Three stages of work with specific actions and legal references.

Stage 1. Site preparation

The person responsible for preparation performs the measures in clauses 373-376 of the Fire Safety Rules:

Stage 2. Execution

The person responsible for execution is continuously on site (clause 377 of the Rules). Not "checking in once an hour", but standing nearby. Accident-investigation practice shows: a few minutes without supervision are enough for sparks to reach insulation or unprotected structures. Result: fire, fine, investigation.

The welder starts work only after all preparatory measures are complete, the targeted briefing is conducted, and on personal instruction from the person responsible for execution. At any deviation (smoke, odour, change in the gas-air atmosphere) the work is stopped immediately.

Stage 3. Closing

Upon completion of hot work the responsible person inspects the site, heated structures and adjacent rooms. Clause 378 of the Rules requires monitoring the site for:

• no less than 2 hours after completion at ordinary facilities,
• no less than 4 hours in explosion-fire hazard zones.

The performer extinguishes stubs and removes equipment. The responsible person enters the closing record and signs. The second copy is returned to the issuer.

Specifics for HIF

At hazardous industrial facilities, additional requirements are added to the standard procedure:

Gas-hazardous permits: "Gas-Hazardous Work Permit: Requirements and Procedure". Organisation algorithm: "Permit Work Organisation: Procedure».

Combining with other types of work

In practice, hot operations are often combined with other hazardous activities. The paperwork procedure depends on the type of combination:

Validity and storage

One of the most common questions among OSH specialists: "How long is a hot work permit issued for?" The answer depends on the category of the facility.

At HIF the permit is issued strictly for one shift. Extension is possible only under unchanged conditions, confirmed by a repeat gas analysis. For scheduled maintenance, the document is issued for the entire maintenance period with daily extension (clause 126 of Order 528).

For facilities outside the HIF category, the Fire Safety Rules do not establish a strict one-day limit. However, methodological recommendations from the Russian Ministry of Emergency Situations point to daily re-issuance. The form contains rows for daily admission.

When a permit is not required

Issuance is not required in three cases:

1. Stationary welding post: a shop or area with exhaust ventilation, a non-combustible base and extinguishers. The post is included in the list by order of the manager. Stationary posts are prohibited in explosion-fire hazard rooms.
2. Construction site: excluded by clause 372 of the Rules. However, Order of the Ministry of Labour No. 884n dated 11 December 2020 (Safety Rules for Electric- and Gas-Welding Work) establishes its own obligations: briefing, protective equipment, risk assessment.
3. Private household: also excluded from clause 372 of the Rules.

Even without a formal permit, the employer is obliged to ensure safe conditions: fire safety instructions, ventilation, extinguishers, access only for certified welders.

Penalties and criminal liability

Welding without a permit (where one is required), with filling violations, without site preparation or with uncertified personnel: all of these are grounds for liability. Sanctions are divided into two categories.

Administrative fines (Code of Administrative Offences, as amended 23 March 2026)

Criminal liability (Criminal Code of the Russian Federation, hereinafter — CC RF)

Article 219 of the CC RF (violation of fire-safety requirements) is especially relevant for hot work: ignition is a direct consequence of violations of fire-hazardous operation rules. Personal liability is borne by the manager who issued the permit and the person responsible for execution.
