What are the regulatory requirements for fire truck turning areas?
1 Answers
Fire truck turning areas have the following design requirements: The width of fire lanes should not be less than 4m. The turning radius should not be less than 9~10m, and not less than 12m for heavy fire trucks. When passing through building entrances, the clear height should not be less than 4m, and the operating slope for fire trucks should not exceed 3%. High-rise buildings should be surrounded by circular fire lanes. When circular fire lanes are difficult to implement, fire lanes can be set along both long sides of the high-rise building. Fire lanes should be at least 5m away from high-rise building exteriors, and there should be no obstacles within 4m above the fire lanes. In residential areas, the length of cul-de-sac roads should not exceed 120m, and a fire truck turning area of no less than 12m*12m should be provided. (Considering traffic convenience and landscape effects, turning areas are generally required when cul-de-sac roads exceed 35m). Cul-de-sac fire lanes should have turning lanes or turning areas. For multi-building complexes, the turning area should not be less than 12m*12m, while for high-rise buildings, it should preferably not be less than 15m*15m. Circular fire lanes should have at least two connections with other lanes. Cul-de-sac fire lanes should have turning lanes or turning areas, with the turning area not less than 12m×12m; for high-rise buildings, preferably not less than 15m×15m; for heavy fire trucks, preferably not less than 18m×18m. Turning areas for large fire trucks should preferably not be less than 18m*18m. Note for "L" shaped, "T" shaped, and "O" shaped configurations.
