BS EN 12101-3:2015, Smoke and heat control systems. Specification for powered smoke and heat control ventilators (Fans). This European standard specifies requirements and test methods for powered smoke and heat control ventilators (fans). These fans are designed to function within a smoke and heat control system and are crucial for clearing smoke from large buildings, car parks, or atriums during a fire. The standard includes tests for their ability to operate reliably at elevated temperatures for a specified period. This ensures that in a fire scenario, the fans will not fail due to the heat and will continue to perform their life-safety function of extracting smoke, improving conditions for escape and firefighting. This page provides a structured summary, key provisions, and practical guidance on the application of BS EN 12101-3 Smoke ventilators to UK fire safety engineering, building design, and Building Safety Act compliance.
