Do you know how to use PVC lay flat hose when fire comes?

In order to ensure the safety and accident-free in summer, the police, patrol, property security, second landlords of foreign apartments, shop operators and principals of key places jointly under the jurisdiction of Shangsha Community have recently launched fire safety activities.
The staff explained the definition of fire, how to distinguish the level, how to use fire extinguishers, how to extinguish fire and save oneself, PVC lay flat hose connection and other basic knowledge.
A small fire was also simulated. Light wood in a small barrel. Then, the narrator picked up one of the bottles of fire extinguisher, about 5 meters away from the burning place, holding the spray gun in one hand, and lifting the open lifting ring on the cylinder in the other hand. When the dry powder is ejected, it sprays rapidly at the root of the flame until it extinguishes. “If the dry powder fire extinguisher is built-in gas storage cylinder or pressure storage type, the safety pin on the opening handle should be pulled down first, then the root of the nozzle at the front end of the spray hose should be grasped, and the other hand will open the pressure handle and press it down, then the fire extinguisher should be opened for spray extinguishing.” Staff said that when dry powder fire extinguishers are used to extinguish flammable and flammable liquid fires, the root of quasi-flame should be sprayed. If the liquid fire being extinguished is flowing and burning, aim at the root of the flame from near to far, and sweep left and right until the flame is completely extinguished.
Next, the staff demonstrated how to use PVC lay flat hose. Only the community workers took out the PVC lay flat hose and tightened the connection with the hydrant clockwise. Then at least two people hold the water gun and aim at the root of the fire site to extinguish the fire.
