Motherwell & Wishaw stair and corridor smoke control
For smoke-vent quotes in Motherwell & Wishaw we start from the published geography: North Lanarkshire, Scotland, 125,610 usual residents in 2020 (NRS settlements 2020). We do not invent a local depot to match the place name. The wider settlement name on the NRS table is Bellshill, Carfin, Holytown, Motherwell, New Stevenston, Newarthill, Newmains, Viewpark, Wishaw. Scottish technical standards are not a renamed copy of English Approved Document B. The vent still has to match the fire strategy written for the building. Classification on that source: Settlement.
Air handling is the other half of this service
Some plant rooms contain an AOV panel and an air-handling unit. The AHU’s fire interlock should stop comfort fans fighting a smoke path. We record the two systems on separate lines so a passed stair vent cannot hide a fan that only runs in hand.
Roof hatches fail in the weather
Head-of-stair lids take wind, water and bird mess. A perished cable gland full of water presents as a dead actuator. We look at hinges, the closer and the cable crossing the roof before we condemn the motor. A lid left open after a test is a leak on the top landing as well as a controls fault.
Automatic opening vents are life-safety smoke control, so this sits with fire protection and is quoted across the UK. Population figures are the published resident counts named above. They are not a survey of vents in Motherwell & Wishaw.
