Car Park & Loading Bay Fume Extraction
CO/NOx ventilation systems for enclosed car parks and loading bays
Workplace Air Quality Protection
Enclosed car parks and loading bays accumulate toxic vehicle emissions—carbon monoxide (CO), nitrogen oxides (NOx), and diesel particulates. Mechanical ventilation dilutes harmful gases below workplace exposure limits, protecting occupants and meeting COSHH obligations.
Inadequate ventilation causes dangerous gas accumulation, occupant illness, and statutory exposure limit breaches. Annual testing verifies sensor calibration, fan performance, and control system response ensuring timely activation before hazardous concentrations.
System Components
CO/NOx Sensors
Gas monitoring sensors triggering ventilation boost. Annual calibration and response testing prevent sensor drift and false readings.
Extract Fans
Supply and extract ventilation achieving air change rates. Fan duty testing and motor condition assessment prevent performance degradation.
Control Systems
BMS integration with staged ventilation response. Control logic testing and alarm function verification ensure correct system operation.
Fire Interlocking
Fire alarm interface for smoke control mode. Interface testing prevents conflicting ventilation strategies during fire evacuation.
Testing & Compliance
Car park ventilation testing follows CIBSE Guide B, HSE workplace exposure limits, and COSHH requirements:
- Annual functional testing by ventilation specialists
- CO/NOx sensor calibration using certified test gases
- Fan duty testing—airflow, pressure, and motor performance
- Control system response verification at trigger setpoints
- Staged ventilation mode testing—normal, boost, and fire
- BMS integration and alarm function testing
- Fire interface verification preventing ventilation conflicts
- Documented certification with gas concentration records
Risks of Non-Compliance
Untested car park ventilation systems expose organizations to:
- →Toxic gas exposure: CO accumulation causing occupant illness, unconsciousness, and potential fatalities in poorly ventilated spaces
- →COSHH breaches: Exceeding workplace exposure limits for CO and NOx resulting in HSE prosecution and improvement notices
- →Tenant complaints: Poor air quality causing health concerns, lease disputes, and reputational damage for commercial landlords
- →Insurance invalidation: Policies void without testing certification, sensor calibration records, and workplace exposure monitoring
