Smoke control

Smoke control study focuses on fire safety in residential care buildings

Warringtonfire has completed a smoke control study, the second in a series of three studies aimed at helping to better protect those in residential care.

Warringtonfire, a fire testing, inspection and certification service, was requested to provide these studies by the Flemish Government.

When asked about the goals of the second study, also called the VIPA2 study, Pieter Poppe – Project Manager, stated, “We wanted to identify the effectiveness of smoke control measures by means of five large-scale fire tests and additional CFD-simulations (CFD: Computational Fluid Dynamics) as part of the evacuation strategy for non-self-reliant occupants of a residential care building.”

The VIPA2 study led to new ways of considering fire safety for more vulnerable members of society, such as citizens who reside within care buildings. Since common areas within these buildings can currently include combustible materials (e.g. kitchens, sofas, etc.), a possible fire hazard is inherent in these evacuation routes. This risk is currently not considered within the concept of the current (Belgian) fire safety regulations.

“The VIPA2 study has scientifically demonstrated the effectiveness of different kinds of applications of a smoke control system in a residential care building. This kind of smoke control system is not only limited to residential care buildings, but can also be applied to all types of structures with similar geometry. Such application is not mentioned in any normative document related to Smoke and Heat Exhaust Ventilation systems (SHEV-system) and is therefore very innovative.”

This completed research, has informed a further third study, the VIPA3 study.

Pieter, who is also Head of the Consultancy Department of the Institute for Fire Safety (ISIB), said: “In the VIPA3 study, an assessment framework has been developed where minimum fire safety measures are determined as part of the evacuation strategy (i.e. immediate evacuation or Defend in Place) in case of non-self-reliant occupants of a residential care building. These fire safety measures can be active (e.g. residential smoke control system, fire screen, automatic extinguishing) or passive safety measures (e.g. fire resistant door, smoke control door, fire resistant damper). The effectiveness of the applied fire safety measures has been demonstrated through large-scale fire tests and additional CFD simulations (CFD: Computational Fluid Dynamics) as described in the VIPA1 and VIPA2 studies.”

The three studies will act as stepping stones in creating a safer and more secure future for non-self-reliant individuals, by potentially guiding future regulations, says Warringtonfire.
