Exhaust gas that they produce smaller quantities of toxic pollutants (e.g. oxides of nitrogen) than petrol and diesel engines of the same power. They produce larger quantities of carbon dioxide but less carbon monoxide due to more efficient combustion. Researchers from the University of California, Los Angeles School of Public Health say preliminary results of their statistical study of children listed in the California Cancer Registry born between 1998 and 2007 found that traffic pollution may be associated with a 5% to 15% increase in the likelihood of some cancers. A World Health Organization study found that diesel fumes cause an increase
Gas cabinet Gas cabinet A gas cabinet is a metallic enclosure which is used to provide local exhaust ventilation system for virtually all of the gases used or generated in the Semiconductor, Solar, MEMS, NANO, Solar PV, Manufacturing and other advanced technologies. The primary purpose of gas cabinets is to contain potential leaks in piping and fittings at the cylinder connection. The cabinet must be exhausted by a specifically designed fan and exhaust system. The cabinet exhaust system draws leaking hazardous gasses out of the cabinet. In the case of a flammable gas the cabinet will contain the flame for a period
