Smoke extraction or other protection measures such as pressure differential systems are used to secure escape routes and to meet the demands of defined safety objectives in the case of fire. These measures need to be planed taking into account the requirements of standards and laws. Our experts use different simulation methods as well as standard calculation methods for this purpose.

Smoke tests


For drills of  first-aiders and emergency service personnel the modelling of the thermal properties of a realistical fire and  a smoke free layer is not always necessary. For the drill purpose is it essential  to provide an as complete as possible smoke logging because this simulates the worst case and allows to test or to check the orientation or evacuation and communication among the personnel during the simulated fire brigade operation. 

Due to its expert knowledge in simulating smoke in real fire tests I.F.I. can fulfil these requirements with its large smoke generators. Example: A four lane highway tunnel is filled with smoke within minutes so that the emergency service personnel could start the drill with their technical equipment, e. g. infra-red camera, close to reality.

Please note: each smoke generator needs a 16A fused 230V-circuit because of the considerable heating power.
