Structural Fire Protection in Buildings
smoke extraction and smoke control systems
According to building law, required corridors and stairwells must be usable for a sufficiently long period of time. The use must not be compromised by smoke. For this reason, smoke vents play an important role in fire protection concepts.
Safety stairwells are especially important security features when incorporated in fire safety concepts and rescue plans. They must be especially secure and are subject to special regulations. No smoke must penetrate safety stairwells at all.
This is the only way to ensure that the safety stairwells are usable at any time by both inhabitants of a building and emergency services.
