AMO AMOT

EOLIOS Ingénierie can support you in your safety and security projects for private and public clients.

We design and estimate the costs of construction, renovation or refurbishment work in the fields of fire safety, SDSI (Schéma Directeur de Sécurité Incendie), explosion, smoke extraction and security, following the various study phases (Diagnosis, Feasibility, APS, APD, PRO/DCE, ACT).

EOLIOS Ingénierie organizes and monitors the work during the execution phase.

EOLIOS Ingénierie assists the project owner during acceptance operations and during the period of perfect completion of the work.

We provide project management and assistance (technical studies, supervision of execution and acceptance) for the design of fire safety systems for new projects or the refurbishment of existing establishments.

COSSI

Our COSSI missions :

Draws up the fire safety concept and functional specifications for the SSI.

Takes charge of monitoring the implementation and technical acceptance of the SSI.

Our SSI Coordination (CSSI) ensure the technical and functional coherence of fire safety systems and are carried out in compliance with the following standards NFS 61-931, NFS 61-932 and NFS 61-970 of all regulatory texts, in particular the “Fire safety regulations for establishments open to the public (ERP)

Thanks to our experience, EOLIOS Ingénierie helps to ensure that regulatory requirements are properly integrated into architectural projects.

Our SSI Coordination (CSSI) assignments include :
  • Analysis of operator requirements, synopsis, concept
  • Writing functional notes and CCFs (functional specifications)
  • Analysis of the minutes of the Safety Commission.
  • Drafting of safety documents for the Inspection Offices and Safety Services at every stage (APS, APD, PRO, DCE): We support you at every stage of the examination of your file by the SDIS Prevention Department, right up to the Notice of Authorization to Open issued after the Safety Commission has passed.
  • In collaboration with all team members, we draw up the fire safety specifications to be included in the building permit or works authorization application.
  • Design and dimensioning of smoke extraction systems in compliance withIT 246.
  • Studies of rescue resources(Articles MS)
  • Participation in meetings with the Bureau de Contrôle to fine-tune the project, particularly prior to the launch of the consultation process, to draw up the preliminary report for the submission of a PC or AT.
  • Collection and analysis of the documents and plans produced by the contractors, enabling a SSI Identity File to be submitted at the end of the operation, in accordance with appendix B of NF S 61-970.
  • Verification of proper execution of SSI work with participation in site meetings
  • Acceptance of work on the SSI with the creation of a typical or replacement fireplace => RRT
  • Monitoring the removal of reservations and drawing up the SSI acceptance report.

Fire safety and smoke control engineering

Smoke and smoke extraction audit

EOLIOS carries out smoke ventilation audits => audit, expertise in smoke ventilation systems (natural, mechanical) in ERP, IGH, BUP, ICPE.

Our multidisciplinary teams are made up of senior fire risk engineers, former firefighters and engineers specializing in fire-related fluid mechanics.

Smoke extraction engineering

It is imperative to design the installations with adequate occupant safety and compliance with fire safety rules. Our studies help architects and engineers simulate fire and smoke spread to design smoke control systems for buildings, subways and other installations open to the public.

The aim is to assess and understand the airflow profile and smoke propagation over time in the space concerned during a fire. The study also highlights possible design improvements by monitoring airflow patterns, identifying pockets of dead air, assessing average air age, fan projection and building air velocities.

It is possible to evaluate smoke control system performance using CFD analysis, and study smoke movement, temperature and visibility profile under various fire scenarios.

Change of scenery planned for 2024: essoc law

Project owners can call on EOLIOS Ingénierie (ORC) to propose SEEs; submit an application file to obtain a certificate of compliance with fire safety objectives; ORC will analyze the file, validate the SEEs and produce a certificate of compliance with objectives; once the work has been completed, the auditor will certify compliance with fire safety objectives, if the objectives have been met.

"In 2024, EOLIOS is undergoing ORC accreditation, more information to come."

To this end, EOLIOS ingénierie can assist its customers with ISI studies of smoke ventilation and RCCI.

Specialized in fire safety master plans for ERP (types U, J, O, R, L, P, S…), IGH, ICPE and industry, ECP management ing relies on several recognized tools:

  • MOSAR and SADT (ENVISION software used in the aeronautics sector)
  • INSSI (CNPP tools and standards 6011, R8, R6)
  • AGR (overall risk analysis) and analysis

Regulatory documents

Regulatory requirements: the law

Regulatory requirements must be applied. The aim is to protect the worker. Any deviation from the regulations entails legal risks for the site operator. Compliance with each requirement must be justifiable on request. Experience has shown that it is complex, but possible in the industry to change certain requirements thanks to solid, legitimate arguments. The agreement of the competent authorities remains imperative.

The Labor Code

The purpose of the French Labor Code is to set the standard for employees’ working conditions. As far as safety is concerned, a simple principle has been generalized: employers are required by law to take all necessary measures to ensure the safety and protect the physical and mental health of their employees.

The requirements of the French Labor Code are a minimum requirement for limiting the employer’s liability in the event of an accident.

The Environment Code

The French Environment Code specifies the rules governing the design and operation of relatively large industrial sites. The general rule regarding fire is that any disaster must be contained within the site.

The requirements of the French Environment Code relate to the ICPE classification of the site. Each activity has its own requirements. In particular, it includes major requirements for smoke extraction.

Prefectoral decrees

Prefectoral decrees are often a marriage between the environmental code, the labor code and the operating application file. They must be systematically included in studies if they exist.

Texts designed for Etablissement Recevant du Public (ERP) and impacting industrial buildings

A number of texts define the design rules to be respected in the construction and operation of an ERP. Highlights include:

Arrêté du 25 juin 1980 portant approbation des dispositions générales du règlement de sécurité contre les risques d’incendie et de panique dans les établissements recevant du public. It should be taken into account when planning tours and parking facilities.

IT246 & IT263: smoke extraction rules to be taken into account following the decree of August 5, 1992.

Standards

The standards that are fundamental in ERP are less important in Etablissement Recevant des Travailleurs and Installations Classées pour la Protection de l’Environnement. They are mandatory when they are mentioned in legal texts. However, the French Labor and Environmental Codes make little mention of them in the field of fire safety.

The French Standards Association (AFNOR) publishes French standards. It should be noted that fire safety standards are generally not enforceable, with the exception of SSI coordination applicable to ERP.

Atossa recommends the use of standards wherever legally necessary, and the use of insurance standards (APSAD – NFPA) in all other cases.

  • NFS61-931: General provisions
  • NFS61-932: Installation rules for fire safety systems (S.M.S.I.)
  • NFS61-970: Installation rules for fire detection systems (S.D.I.)
