How to ensure the fire rescue channel when setting up stalls in pedestrian commercial streets and residential markets?

When setting up stalls in pedestrian streets and residential trade markets, we should pay attention to the following aspects in order to ensure fire rescue channels:

1) The width of the pedestrian mall should consider not only the width of pedestrians calculated according to the flow of people, but also the width of the passage required for fire engines to pass and stop for rescue.

2) When the length of the pedestrian mall is greater than 150m, a fire lane should be set in the middle to enter the pedestrian mall. The fire lane crossing the pedestrian street should be connected with the urban road network.

3) The distance between the buildings on both sides of the pedestrian street and the width of the opening at the end of the pedestrian street shall meet the safe distance between the fire escape (4m) and the buildings on both sides (both are not less than 2.5m).

4) Set up trade markets or commercial stalls in residential areas, and do not block the passage of fire engines or affect the use of fire hydrants.
