Fire Safety in Underground Car Parks: Design and Management Guide

Underground car parks present significant fire safety challenges. We cover ventilation, detection, suppression, and EV considerations.. Underground Car Park Fire Safety Underground car parks combine enclosed spaces, vehicle fire loads, fuel vapours, and increasingly, electric vehicle charging. Design Requirements Ventilation : BS 7346 7 compliant smoke extract system Detection : Heat detectors at ceiling level, linear heat detection optional Suppression : Sprinklers recommended for enclosed parks 1 level below ground Structural fire resistance : REI 120 minimum for underground structures Separation : Fire rated separation from building above For car park fire engineering, contact us.
