Fire Safety Engineering: The Key to Anticipating Fire Risks in Public Access Buildings (PAB)

To comply with fire safety regulations applicable to Public Access Buildings (PAB) or to address potential fires, your objective is to ensure the safety of employees, visitors, and patients.

Fire Safety Engineering is a method used to evaluate alternative provisions to regulations for non-standard or rehabilitated structures. Based on CNPP's proprietary methodology, a rich database of over 60 years of experience, and smoke extraction tests, our experts evaluate and perform smoke extraction engineering services.

• 3D digital reconstruction of the space to be smoke-extracted (using CFAST zone models or FDS field models).
• Proposal of fire scenarios aimed at testing a smoke extraction system and its related safety strategy under real conditions (majorizing scenarios based on regulatory fires / realistic scenarios adapted to the studied installations), implementing the methodology developed under PN-ISI.
• Study of the effectiveness of natural or mechanical smoke extraction systems; relative evaluation approach for complex systems regarding their compliance with a reference regulatory system.
• Opinions on building smoke conditions, proposing alternative or innovative measures designed to enable evacuation or ensure the safety of occupants in the event of a declared incident.

Assistance in the design, evaluation, and optimization of fire safety systems through modeling.

• Applicable to all types of buildings: Warehouse, Worker Access Buildings, nuclear power plan
• Evaluation of activation times for detection systems, sprinkler systems.
• Effectiveness of inerting systems.
• Thermal stress and structural resistance.

• Calculations for temperature rise of a structure or equipment near a fire.
• Possible fire/structure coupling with fire resistance models simulating the effect of thermal aggression on building structural elements such as concrete beams, metal structures, etc. (Specific engineering study for warehouses subject to authorization under ICPE section 1510 targeting sprinklered cell sizes exceeding 6000 m2).
• Engineering study aimed at evaluating and selecting extinguishing agents and extinguishing systems compatible with the risk to be protected and the operator's constraints.
• Evaluation by calculation or experimentation of alarm activation times for fire detection systems according to the envisaged fire scenarios.
