Tests of the High Pressure Fire Service in New York City, 1908.
Between 1904 and 1908 the Department of Water Supply, Gas and Electricity designed and built the NYC High Pressure Fire Service system. Comprised of pumping stations, distribution pipes and high pressure hydrants, the HPFS, as it came to be known, was designed and built after a devastating fire in Coney Island in 1903, followed by the fire that destroyed the Baltimore business district in 1904.

To solve the fire protection regulations in the open-plan structure of the Mercedes-Benz Museum, a unique smoke elimination system was developed: an artificially generated tornado.
In the event of a fire, outlets located along the core walls inject air into the interior courtyard of the Museum generating an artificial tornado which collects the smoke and then discharges into the outside air.
