BS EN 12101-6:2022, Smoke and heat control systems. Specification for pressure differential systems. Kits. This European standard specifies the requirements and test methods for pressure differential systems and their components. These systems are used to keep escape routes, such as staircases and lobbies, free from smoke by maintaining a higher air pressure in the protected space compared to the fire area. This prevents smoke from entering, ensuring escape routes remain tenable for occupants and accessible for firefighters. The standard covers the complete system kit, including fans, ductwork, and controls, and is essential for the design, installation and commissioning of these critical life-safety systems in complex buildings. This page provides a structured summary, key provisions, and practical guidance on the application of BS EN 12101-6 Pressure differentials to UK fire safety engineering, building design, and Building Safety Act compliance.
