Underground Car Parks and EV Charging: The Fire Safety Challenge

The proliferation of EV charging in underground car parks creates one of the most challenging fire scenarios.. Underground EV Charging Fire Safety Underground car parks with EV charging combine the worst case fire scenarios: difficult access, toxic gases, extended fire duration, and limited ventilation. Critical Design Measures Enhanced sprinkler protection (OH3/OH4 density) in EV bays Smoke ventilation capacity for prolonged EV fires (3+ hours) Structural fire resistance increased to REI 120 minimum Linear heat detection along charging infrastructure Toxic gas detection (HF, CO) with ventilation interlock Drainage designed for contaminated firefighting water Firefighter access strategy specifically for EV fires For EV car park fire engineering, contact us.
