What's in the fire engine?
Setting requirements of fire lane in built-up areaEspecially the old city area of built-up area often due to historical reasons, poor traffic conditions, fire water supply shortage in the inflammable built-up areas is also mixed with small factories, warehouses, and residential cross. The old city area of small towns, but also often is a bustling business district, is regarded as "lots of gold", the residents shop sale, road occupied, temporary buildings, booth adjacent to a narrow channel, once the fire, easy to form huoshaolianying. The built-up area in general has the fire lane, the fire lane should be kept open, any units and individuals are forbidden to occupy the fire channel, take the house heap, shetan. The existing urban flammable building concentrated areas should be integrated with the overall urban planning, gradually transformed, conditional renewal can be carried out. Fire lane is generally not allowed to park other vehicles, residents should be discouraged from building illegal structures and piling up articles.
Factory, warehouse, storage yard, storage tank area and large public building fire lane setting requirementsAccording to the fire squadron in the fire fighting practice reflect the larger area of the factory, warehouse, yard, tank fire, burning fast, fierce fire, fire fighting over a long period of time, if there is no fire ring lane and Esplanade, is bound to cause fire vehicles not only into, is bound to cause blockage, so that fire engines to near the fire, therefore, factories and warehouses should set the fire lane. A a, B and C plant covers an area of over 3000 square meters or a B C warehouse covers an area of over 1500 square meters, for the passage of fire engines and a width of not less than 6m of the Esplanade set along the two long side. Flammable and combustible materials, open storage yard area, liquefied gas storage tank area, a, B, C liquid storage area shall be provided with fire lanes or flat spaces for fire engines which are not less than 6m in width.More than 3000 seat stadium, more than 2000 seats in the synagogues and covers an area of over 3000 square meters of exhibition hall and other large public buildings, because the construction of large volume, large area, and personnel intensive, in order to facilitate the occurrence of fire fighting and evacuation, are advised to set up a ring of fire lane.
Fire lane settings should be comprehensive, the road load is too small, the road below the pipe is too shallow, and the ditch used light cover plate, etc., can not withstand the passage of large fire engines. In addition, as can be seen from the table, due to the large fire truck body length and minimum turning diameter is too large, therefore, enter the field set the fire lane for 12 * 12m was impassable, enter the field to set a larger area to meet the use requirements, it shall be determined according to the local actual equipped with large fire engines.
The length, width and height of fire engines are a decisive factor affecting the capacity of fire lane. The length of the general fire engine is greater than or near 10m, the height is near 4m, and the width is near 2.5m. "Building regulations" article 4.3.4 and article 6.0.2 of the "high regulation" provisions of the fire lane through building the height and width of not less than 4m, is in accordance with the various dimensions of fire vehicles for domestic use and determined. Taking into account the speed of fire engines generally faster, through the building, the width should ensure a certain safety factor, to facilitate rapid access to vehicles, arrived at the fire, and successfully put into battle.
