Requirements for setting up fire lanes in factories, warehouses, storage yards, storage tank areas and large public buildings According to the reflection of each fire fighting squadron in fire fighting practice, When a fire occurs in a large area of factories, warehouses, storage yards and storage tank areas, the fire burns very fast, the fire is fierce, and the fire fighting lasts for a long time.

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.Don't get down on the slightest thing.
