![]() See the table below for details.īayonet, Barcelona, Guillemin, Klaue, Sprawny, Storz, UNI If flow_rate=* is present, this tag is redundant. In the US, classification per American Waterworks Association. The use of usgal/min or ukgal/min instead of gpm is necessary because UK and US gallons are different. In the United States, this specification is in gallons per minute. In France, a normalized fire hydrant needs to supply 120 m 3 during two hours. # (numeric value) with unit of measure, in International System standard unit is m 3/s, but for hydrants are preferable l/min (liters per minute), usgal/min (US gallons per minute), ukgal/min (UK gallons per minute), or m 3/h (cubic meters per hour). If fire_hydrant:awwa_class=* is present, this tag is redundant. Other numbers are the distances in meters of the hydrant from the sign (on the left / on the right / frontally). In Belgium and Germany, the number on the top of the sign (H 250) is the nominal diameter in mm of the underground pipe that feeds the hydrant. Hydrant consisting of a simple capped pipe, without the usual hydrant shape If this tag is not specified, pressure is assumed to be unknown.įire_hydrant:type=* details Values for fire_hydrant:type=* Value If the hydrant is connected to a pond/stream/tank/pool and a pump is needed to get water, use fire_hydrant:pressure= suction. If under pressure but you don't know the value fire_hydrant:pressure= yes. Pressure at which the water is supposed to flow through the hydrant. Tag a node with this tag to identify the location of a fire hydrant. 3 How to find an underground fire hydrant: signageįor numeric values with units, see the guidelines: Map Features/Units Basic tags Tag.1.2.1 fire_hydrant:awwa_class=* details.If there is also a pipe present to make it easier to pump water, that pipe can be mapped as a hydrant with appropriate water_source=* and fire_hydrant:pressure= suction (see below). ![]() These inlets do not provide water, on the contrary, they are used to pump water up a building.Ī designated place where fire engines can park to pump water from a body of water (such as a river or lake), is mapped with emergency= suction_point (see the wiki page for that tag). Not to be confused with a emergency= dry_riser_inlet. It may also be known as a fire plug or johnny pump. A fire hydrant is an active fire protection measure, and a source of water provided in most urban, suburban, and rural areas with municipal water service to enable firefighters to tap into the municipal water supply to assist in extinguishing a fire. The tag emergency= fire_hydrant is used to map a fire hydrant: a device to take water for firefighting purposes.
