Fire Safety Engineering

Safety engineering is a method of quantifying and optimising safety levels achieved by works, products or systems.

It is based on the principle of finding out all chains of events that could potentially lead to damage to persons or goods.

Each of these chains of events is a scenario that can be associated with an occurrence probability.

From the whole set of pairs (occurence probability / seriousness of effects), it is possible to quantify the safety margin by a work project and compare it with the level of accepted risk.

Though fire regulation in France generally has a prescriptive approach, the engineering method applicable to fire safety (ISI) can nonetheless provide a mean of ensuring the desired level of security in cases where regulatory requirements are not applicable or with difficulty:

  • Original architecture
  • Ancient sites
  • Industrial buildings

Thanks to its experience in risk analysis and use of models based on large scale calculation, CNPP can give you a technical support with measuring the work and systems contributing to fire safety:

  • Specific engineering study for warehouses subject to order 1510 intended for sprinkler-equipped areas over 6000m²
  • Evaluation by calculating efficiency of natural or mechanical smoke-clearing system – experimental validation on-site – measurement proposals

Rackfire modeling

  • Engineering study designed to select the appropriate extinguishing agents and extinguishing systems according to the risk to be prevented and any user constraints

  • Evaluation by calculation or experimentation of alarm delays of fire detection systems following the considered fire scenarios

CNPP is a partner of PN ISI (National Fire Safety Plan) (French FSE project) under l'IREX (Institute for Applied Research and Experimentation in Civil Engineering).

The project bringing together over 35 members has the aim to create a French fire safety engineering methodology; to spread the acquired knowledge through actors information and awareness, by establishing training programmes and by proposing regulatory evolutions.
