Hydra Vehicle exhaust fumes present a health hazard because they contain significant levels of toxic gases such as carbon monoxide (CO) and oxides of nitrogen (NO/ NO2). Exhaust gases can accumulate in enclosed car parks without adequate ventilation; exposure to high concentrations could occur and result in death. Gas detection is therefore essential to control ventilation systems and protect car park workers and users. Addressable gas detection systems cost far less to install than conventional point-to-point systems. The cable and installation/labour cost savings are often greater than...
