Do you run fast or the fire runs fast?

When the fire comes, many people's instinctive reaction is-run. Isn't it safe to run out of the fire? Then let's first look at the speed comparison between humans and fire.

Generally speaking, the speed of flame spreading upwards is 3-4m/s, that is to say, for a high-rise building (about 30 stories) with 100m, it only takes about 30 seconds for the fire to reach the top directly from the bottom. The world record of 100 meter sprint is 9.58 seconds set by Bolt, and it takes about 15 seconds for ordinary people to run 100 meter. But notice that this is the speed on the flat ground. Counting the back and forth of the stairs, it is obvious that human beings can't run fast. Therefore, in the fire, "running" is an extremely particular thing. Once you make a mistake, the consequences will be unimaginable.

High level residents

Learn to use fire hydrants.

When high-rise residents encounter a fire, the first-time self-help and disposal is the most important, so they must learn to use fire hydrants.
