Many existing buildings offer potential for expanding living space, for example, by adding another story to the building or converting the attic. Particularly due to limited building land in urban areas, the expansion of existing buildings is becoming increasingly important in urban development.
However, building expansion or the addition of another story requires a second escape and rescue route. Consequently, a second emergency stairwell or a rescue option using fire department equipment is necessary. This poses a significant problem, particularly for taller buildings in densely built-up downtown areas (e.g., due to narrow streets or trees).
As a result, the fire department’s turntable ladder often cannot be deployed. Consequently, a safety stairwell or a second (external) emergency stairwell is necessary.
The latter often presents building owners with an insurmountable problem. The building’s location often does not allow for a second stairwell that meets fire safety requirements. Consequently, the retrofitting of existing buildings is hindered.
Safe escape route with water mist
As a substitute for a second escape and rescue route, alow-pressure water mist suppression system can be installed in the building. It facilitates the expansion of living space in existing buildings without major structural measures such as a second escape stairwell.
Furthermore, the system enables all building occupants to safely use the stairwell in the event of a fire. As a result, water mist fire suppression systems are already recognized as a verified solution by the Department of Urban Development and Housing in a major German city with over one million residents.
The Advantages at a Glance
- Easier creation of living space without a second escape and rescue route
- Quick installation, resulting in minimal disruption to residents
- Easy retrofitting with an emergency power supply in the event of a power outage
- Safe escape stairwell for at least 10 minutes and compliance with fire safety requirements
- Cost advantage over installing a second escape and rescue route
- Combination with other fire protection systems
Our low-pressure water mist suppression system
CWS Fire Safety offers a sustainable and cost-effective alternative for a second escape and rescue route using a low-pressure water mist suppression system. This allows for the creation of additional living space within a building while meeting fire safety requirements in the stairwell. Furthermore, it enhances safety for all building occupants.
How Water Mist Suppression Systems Work
Low-pressure water mist suppression systems atomize the water so finely that the water’s surface area is greatly increased. This creates a cooling and smothering effect that is highly effective in fighting fires. The fire is thus tackled on two sides of the fire triangle:
- Cooling the fire and the surrounding area
- Absorption of radiant heat and oxygen
- Suppression of smoke gases
We exclusively design and install low-pressure water mist fire suppression systems from the Danish manufacturer VID Fire-Kill. Our systems comply with the current DIN EN 14972-1:2020 standard. The experts at the Competence Center for Low-Pressure Water Mist Fire Suppression Systems will be happy to advise you.
Our Solution in Detail
Our low-pressure water mist fire suppression system, which serves as an alternative to a second escape and rescue route, can be easily and cost-effectively installed in a building. To do this, a water mist nozzle is installed on both sides of each apartment entrance door .
