KIT-PE STAIRSHIELD COMBATOR FOR FIRE SAFETY IN BUILDINGS
A stair pressurization system is considered a fire safety system for several reasons:
1. Smoke control: In case of fire, smoke is one of the greatest dangers to human life in a building. By pressurizing stairs, smoke can be prevented from entering them, providing a safer escape route for people trying to evacuate the building.
2. Improved visibility: By keeping stairs smoke-free, visibility is improved, making evacuation easier and allowing people to find their way out more quickly.
3. Safe evacuation: By providing a safer environment on stairs, an orderly and rapid evacuation of the building is facilitated, which can help reduce the risk of injury and loss of life.
4. Temporary shelter: In situations where complete evacuation of the building is not immediately possible, pressurized stairwells can serve as temporary shelter for people trapped in the building, protecting them from smoke and heat until they can be rescued by emergency personnel. emergency services.
STAIR PRESSURIZATION SYSTEM KIT-PE STAIRSHIELD
KIT-PE STAIRSHIELD stair pressurization kit and COMBATOR fire brigade panel in accordance with European regulations UNE-EN 12101-13:2022. This kit allows the management of 1 or 2 fans, and up to 2motorized regulation dampers.
FUNCTION OF THE STAIR PRESSURIZATION KIT IN BUILDINGS
The stair pressurization kit is a system designed to maintain positive air pressure or overpressure in an enclosed stairwell or vertical escape space, such as an emergency exit, during a fire or other emergency.
When a fire occurs in a building, such as an office, a hallway, a lobby, or even a parking lot, hot air and smoke tend to rise and accumulate in the upper spaces of the building, including stairs. If the stairs are not pressurized, the smoke and heat find a perfect way to ascend, which would be the stairwell. This fact would make it difficult and/or impossible for people to escape from the building and for emergency teams to access the interior of the building.
GENERATE POSITIVE PRESSURE FOR PEOPLE EVACUATION
Stair pressurization helps prevent smoke and heat from entering enclosed stairwells and other vertical exhaust spaces by maintaining positive air pressure in the space. This positive pressure prevents smoke and heat from entering the stairs, allowing greater safety in the evacuation of people and the entry of emergency teams.
Additionally, pressurizing stairs can also help maintain a viable escape route for people in other parts of the building by preventing smoke and fire from spreading through the stairs to other adjacent floors in the block.
NEW REGULATIONS OF STAIRCASE PRESSURIZATION IN BUILDINGS
Since November 2022, the European standard UNE-EN 12101-13:2022 has been in force in Spain, which, together with UNE-EN 12101-6:2022, cancels and replaces the previous UNEEN 12101-6:2006. All standards will coexist until 01.02.2024, but from then on only UNE-EN 1210113:2022 and UNE-EN 12101-6:2022 will be valid.
Until the arrival of the new standard, it was only necessary to install a stair pressurization kit that automatically managed the operation of the fan to maintain a differential pressure of 30 to 50 Pa in the escape route.
The new standard involves the installation of this kit next to a fire department that allows them to control and monitor the stair pressurization system from a central location. This box in Casals Ventilación is COMBATOR.
SHIELD-KIT SET
In order to achieve pressurization of stairs, there are sets that facilitate installation by being composed of all the necessary elements in a compact way. SHIELD-KIT is a set that allows you to control a motorized regulation damper and a fan. If smoke is detected, the damper will close and the fan will stop so that smoke does not enter the stairs.
