Underground car park gas detection is commonly fitted for environmental protection and energy cost saving. If there is no exhaust gas pollution present, then ventilation rates can be reduced to save energy. The building regulations specify what is required to maintain safe conditions, specifically section F which highlights the gas detection. This is a very effective energy reduction solution, provided the air quality is correctly monitored with suitable gas detectors. GasWatch design effective systems utilising our extensive experience of these applications. We regularly supply systems for carbon monoxide monitoring (CO), Carbon Dioxide (CO2), Nitrogen Dioxide (NO2) and Flammable gases such as LPG detection (for enclosed car park applications). This is dependent upon the client’s requirements and vehicle profiles.

Carbon Monoxide is always the primary detector in this application as it poses the biggest threat to life. Other gases must be considered. If the underground area is primarily a “goods delivery point”, then Nitrogen Dioxide should be included as this is produced from diesel fuelled delivery vehicles. Similarly, in countries with higher densities of LPG, Ethanol or Hydrogen fuelled vehicles, flammable gas detectors may be included to counter heavier than air fuel leaks. These can form significant explosive atmospheres in underground areas where concentrations can quickly accumulate.
