Strabane stair and corridor smoke control
Strabane (County Tyrone, Northern Ireland) has a published usual-resident population of 13,506 in 2021. Source: Northern Ireland settlement population (published Ireland list, NI jurisdiction). That figure is residents, not a count of blocks with smoke vents. Classification on that source: Settlement. Fire safety law and building regulations in Northern Ireland are not the English Approved Document B set. We quote to the strategy and the rules that apply there, and we say so on the visit record.
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 Strabane.
