The publication of the Technical Guide for the Application of the Fire Safety Regulations in Industrial Establishments has generated numerous inquiries within the sector. Developers, industrial building managers, and manufacturing companies need to understand how this update affects their current and future projects. Therefore, in this article, we develop a RSCIEI 2025 summary Clear and practical, focused on explaining what really changes and how it should be applied correctly.

The RSCIEI is the regulation that governs fire safety in industrial establishments in Spain. The 2025 Technical Guide does not replace the regulation, but it does clarify technical criteria that, in practice, generated interpretive doubts. RSCIEI 2025 summary Its objective is to translate these criteria into understandable language without losing technical rigor.

What is the Technical Guide for the Application of the RSCIEI 2025?

The 2025 Technical Application Guide is a document published by the Ministry of Industry that develops and interprets the Fire Safety Regulations for Industrial Establishments. Its purpose is to unify criteria and reduce discrepancies between administrations in the processing of projects.

The official document can be consulted at the Ministry of Industry:

This RSCIEI 2025 summary This allows us to understand that the guide does not generally tighten the regulations, but it does require greater technical precision in the justification of the solutions adopted in fire protection projects.

Determining intrinsic risk: the starting point

One of the most relevant aspects that we address in this RSCIEI 2025 summary It is the determination of intrinsic risk. This parameter is the basis on which fire protection measures are designed.

The guide specifies how to correctly calculate the weighted fire load and how to handle common situations such as:

• Mixed activities within the same building.
• Administrative zones integrated into industrial spaces.
• High-bay storage.
• Auxiliary or technical areas.

An appropriate classification of intrinsic risk determines the maximum sector area, structural resistance, and the mandatory nature of certain automatic systems.

Sectorization and compartmentalization

Sectorization is another pillar that is being reinforced in this RSCIEI 2025 summary. The guide provides greater clarity in cases that previously generated doubts, such as extensions of industrial buildings or attached buildings in industrial parks.

Criteria are needed regarding:

• Maximum fire sector areas.
• Separation between sectors with different levels of risk.
• Treatment of party walls.
• Compatibility between different construction configurations.

These clarifications are especially relevant in renovation or expansion projects, where it may be necessary to review the entire establishment.

Active protection systems

Another important point we highlight in this RSCIEI 2025 summary It is the interpretation regarding the mandatory nature of active protection systems.

The guide specifies better when they are required:

• Automatic sprinklers.
• Detection and alarm systems.
• Smoke control installations.
• Complementary measures in large logistics areas.

It also strengthens coordination with the Regulation on Fire Protection Installations (RIPCI), which requires a more robust technical justification for each project.

Coordination with the CTE in mixed buildings

Many industrial establishments have offices, administrative areas, or public spaces. RSCIEI 2025 summary It pays special attention to the coordination between the RSCIEI and the Technical Building Code.

The guide clarifies which regulations prevail according to the use of each zone, how solutions in mixed buildings should be justified, and what criteria to apply regarding evacuation and structural resistance.

This coordination is key to avoiding inconsistencies in administrative procedures.

Frequently Asked Questions about the RSCIEI 2025

To complete this RSCIEI 2025 summary, We answer some of the most common questions that arise in industrial projects.

Does the RSCIEI 2025 introduce new obligations?

It does not modify the basic regulations, but it does clarify their interpretation. This implies greater technical rigor in the justification of solutions.

Should I upgrade my existing industrial building?

If there are no expansions or changes in activity, it is not usually mandatory to modify existing facilities. However, in the case of substantial renovations, it may be necessary to review the entire establishment.

What happens if I expand my industrial building?

In the case of expansions, the guidelines state that it must be analyzed whether the intervention affects the entire establishment. In some cases, the expansion may involve updating measures in existing areas.

When are automatic sprinklers mandatory?

It depends on the intrinsic risk, the surface area, and the activity carried out. The RSCIEI 2025 clarifies these assumptions more precisely, reducing ambiguous interpretations.

How does it affect offices within an industrial building?

The guide reinforces coordination with the CTE in administrative or public areas, which may imply additional requirements in evacuation or sectorization.

Applying the RSCIEI 2025 correctly is key

This RSCIEI 2025 summary It demonstrates that the Technical Guide does not represent a regulatory revolution, but it does raise the level of precision and consistency in its application. For industrial companies, this means that fire protection projects must be better grounded and properly justified.

Understanding and properly applying the RSCIEI 2025 Technical Guide is not merely an administrative matter. It is a guarantee of real safety, technical feasibility, and peace of mind during inspections and licensing processes.

At ENGIND, we approach each industrial project holistically, analyzing inherent risk, sectorization, and regulatory compliance from the outset. Our up-to-date knowledge of the regulatory framework allows us to correctly apply the RSCIEI 2025 and avoid interpretations that could lead to delays or cost overruns.

If your company is planning a new industrial building, an expansion, or a change of activity, having a team specializing in industrial regulations makes all the difference. At ENGIND, we can help you correctly implement the RSCIEI 2025 and develop a solid, safe project that complies with current legislation.

Fire safety is not a formality. It is an essential part of the industrial project, and addressing it with technical rigor is the best decision.
