Fire safety
in buildings

Fire safety in buildings is governed by different regulations * depending on the type of building and the use of the premises:
residential buildings,
offices, building open to public (ERP in French),
buildings for professional use (BUP in French),
high-rise buildings (IGH in French),
and medium-rise buildings (IMH in French).

*texts available on et

To ensure the life safety, by helping to avoid the outbreak of a fire, or, in the event of a fire, to limit the fire development, spread, and its effects on people, and to facilitate the intervention of the emergency services, these texts prescribe:

the reaction-to-fire and fire-resistance requirements for products and components of facilities, buildings, and structures.
the measures to be taken to limit the spread of fire through facades.
the principles and requirements of smoke extraction.

Reaction to fire.

Reaction to fire is the capacity of a construction product or its installation to sustain a fire and contribute to its development.

These products are subject to different classifications (Euroclasses or M Classification) specifying their degree of contribution to the development of a fire and their potential for smoke production and also flaming droplets.

The means of proof in terms of reaction to fire are specified by the modified order of November 21, 2002.

Fire resistance.

Fire resistance is the ability of a product, building element or structure to maintain its functionality in a fire situation.

The fire resistance performance of these products and elements, assessed by means of predetermined thermal actions, is expressed in degrees or classes. These degrees or classes are directly related to the periods of time during which the products, construction elements or structures meet the selected performance criteria, depending on their role from a safety point of view.

The means of proof in terms of fire resistance are specified by the modified order of March 22, 2004.

Fire spreading through facades.

Façades must be designed to limit the spread of fire on the façade from one level to another, whether the source of the fire is internal to the building or not: limiting the lateral spread of a fire, its spread on the façade or through the façade-floor junction.

The provisions to be implemented and the means of proof of performance to be provided are specified in the regulatory texts applicable to buildings as well as in Technical Instruction No. 249 (“C + D” rule, mobilizable fuel mass, etc.).

Smoke extraction.

Smoke extraction consists in a space to be cleared from smoke by a flow of air: smoke evacuation on one side and fresh air supply on the other.
The aim is to effectively remove some of the smoke and heat to:

facilitate the evacuation of occupants.
limit the spread of the fire.
allow access to the premises for the fire brigade.

The rules of execution and the principles of the provisions to be implemented in terms of smoke extraction are specified in the regulatory texts, in particular:
for E.R.P.(s): Technical Instructions No 246 and No 263.
for H.R.B.(s): Technical Instruction of 12/30/2011.

They ensure:
the smoke barrier or smoke extraction from staircases. ;
the smoke extraction from horizontal corridors. ;
the smoke extraction of premises accessible to the public.

Your projects are our concerns.

CERIB’s Fire Testing Centre assists you in controlling the fire risk on your projects. Whether you are an industrialist, a company, a project manager or a project owner, our team is at your disposal to provide services adapted to your needs:

Our team also assists in obtaining the means to prove the performance of your new products (ATEx, DTA, ATec, etc.), construction systems and structures in terms of fire safety:

Classification reports.
Laboratory assessments.
Site implementation assessment.
Advice on engineering studies.

The CERIB Fire Testing Centre is:
a laboratory accredited in fire resistance by the French Ministry of the Interior. ;
certified by COFRAC for the performance of fire resistance tests (Accreditation n°1-0001 – Scope available on

Fire resistance tests.

Conventional fire tests:
Load-bearing elements (EN 1365): walls, floors, beams, columns, balconies, stairs, etc.
Non-load-bearing elements (EN 1364 standards): partitions, ceilings, curtain walls, transfer grids, etc.
Technical equipment (EN 1366 standards): sealing, ventilation ducts and smoke extraction ducts of very large cross-section, technical ducts, fluid enclosures and cable trays, ventilators, containment screens, etc.
Doors and closures (EN 1634 standards)
Passive protection (EN 13381) for wooden, steel, concrete, mixed elements, …
Assembly tests: beam-beam on a column, purlin-purlin on beam…
Special tests
Intermediate scale orientation tests

Fire behaviour and
characterization tests.

Fire behaviour tests of building systems with respect to the risk of fire propagation through facades (LEPIR II test**)
Natural fire tests
Thermo-mechanical material characterization tests
