In case of fire, fire can be done by connecting fire hose, but how many roots are there at most?
First of all, fire extinguishers should be considered, because fire extinguishers are easy to use and convenient to take and carry.
Should use the nearest fire hydrant, it is best not to connect more than 2. If you can't use the nearest one for a variety of reasons, you can only use the other one. As far as possible, the less the hose is, the better. Don't forget to start the fire pump
If the fire is large or enlarged, fire hydrants should be opened in time.
