Tong, no unit or individual is allowed to occupy the fire exits to build houses, pile things and set up stalls. The existing flammable building intensive areas in cities and towns should be gradually transformed in combination with the overall planning of cities and towns, and contiguous transformation can be carried out if conditions permit. Fire lanes are generally not allowed to park other vehicles, and residents should be discouraged from building illegal buildings and piling up articles. 3.

Therefore, fire lanes should be set up in factories and warehouses. When a Class a, Class B and Class C factory building occupies an area of more than 3000 square meters or a Class B and Class C warehouse occupies an area of more than 1500 square meters, a flat open space with a width of not less than 6m for fire engines to pass through can be set up along its two long sides. Open yard area for flammable and combustible materials, Liquefied gas storage tank area, For Class a, Class B and Class C liquid storage tank areas, there shall be large public buildings such as fire lanes or flat gymnasiums with a width of not less than 6m and a space of more than 3,000 seats, halls with more than 2,000 seats and exhibition halls with an area of more than 3,000 square meters that can be passed through by fire engines. Because of the large volume, large floor area and large and dense personnel, in order to cause fire, there shall be large public buildings such as the gymnasiums with a flat space of more than 3,000 seats, halls with more than 2,000 seats and exhibition halls with an area of more than 3,000 square meters.
