2, in the process of access to water, it should pay attention to whether the fire hydrant water pressure can meet the needs of fire engines . When accessing natural water sources, attention should be paid to the water depth of the ponds and ponds, silt, etc. to prevent excessive shallow water depths and the intake of intake pipes from being affected by silt and causing water supply interruptions in the fire site.
3. When the water source is beyond the fire station 's direct water supply capacity, the fire truck relay water supply method shall be used to supply the fire field. The driver of the water supply vehicle should pay attention to the overflow of the overflow pipe of the water truck and maintain the proper water supply. When the rear vehicle cannot observe the overflow condition of the preceding vehicle, the driver of the preceding vehicle can open the manhole in the upper part of the tank of the vehicle to prevent the tank rising phenomenon caused by the excessive supply of water. In the process of water supply, the receiving vehicle should choose a hard surface for parking. When it is impossible to park a hard surface, necessary measures should be taken to prevent the vehicle from falling into the quagmire due to overflow. Water supply, should try to use the same type of direct coupling relay in fire vehicles, must be coordinated between the various vehicles, to prevent the improper operation of the water supply is interrupted. When the direct water supply pressure is high, care should be taken to maintain proper water pressure to prevent injury to the combatants.
1, into the fire after the fire vehicle, the vehicle should be parked in accordance with a position designated fire commanders. The parking posture of the vehicle can meet the needs of attacking and retreating the fire field, and it must be ensured that the dangerous position can be withdrawn at any time. The engine of the vehicle keeps running. Never turn off the engine blindly and delay the fighter. When the fire truck starts to supply water, the water pressure should be gradually raised to avoid the casualties of the combatants or the water blasting caused by the reaction force of the water gun and the sudden increase in water hammer, which will affect the smooth development of the fire-fighting and rescue work. During the laying of fire hoses, if there are sharp objects (such as the common broken glass in the fire site) through highways and grounds, the water hoses should be protected, the water hoses must be cut, and the cars must be affected by the roller compaction hoses. Firefighting.
