Why is it said that residential balconies are closely related to fire protection?

Because the large balcony of the residence is generally the part where the ladder for the rescue is reached.

In terms of fire prevention, when a fire breaks out in a room located on the first floor below the balcony, the flames rush out of the window and rise upward, and the reinforced concrete balcony can effectively block the fire that spreads upward; When doors, stairs or corridors are blocked by smoke and fire, and people are trapped in their rooms with no way to escape, healthy young adults who are more courageous can get out of danger by climbing the downspouts by the balcony.

If the balconies are connected, they can be moved in a safe direction.

If you can find a strong rope, you can also use the balcony to go down the rope. In short, people who take refuge on the balcony, even if they are unable to escape, can at least gain some precious time to wait for the firefighters to come to the rescue. There are many successful examples of this.

However, people living in buildings lack awareness of this, many families are affected by the old concept of "a broken home is worth a thousand dollars", and are reluctant to abandon some dilapidated old things, and are accustomed to rotating on the balcony, which has become a "waste material warehouse" for families, with tables and chairs, benches, bamboo baskets, cardboard boxes, broken shoes, firewood and grass, and even flammable liquids such as gasoline, kerosene, paint, etc., all of which are constituting a fire hazard for families. In the unlikely event of a flying fire (e.g. lit fireworks, cigarette butts thrown from upstairs, radiant heat or "flying fires" from other buildings in the event of a fire), combustibles placed on the balcony may ignite. Not only will it set fire to the room, but it will also seriously threaten the safety of the neighbors.

In order to ensure safety, some families ingeniously welded anti-theft fences on the balcony with steel bars to completely cover the balcony. This may seem advantageous from a burglar prevention perspective, but it is clearly disadvantageous from a fire protection perspective. This is because under fire conditions, this fence will make it impossible for people in the house to escape, and it will be difficult for firefighters to extinguish and rescue people smoothly.
