11 safety requirements that should be paid attention to in the fire field

the water gunner is the first-line fighter who fights in the front position of the fire field and directly engages in close combat with the fire, and is also one of the key figures to determine whether the fire is successfully extinguished. "To save oneself is to better destroy the enemy". The safety of combatants on the fire also determines the success or failure of fire fighting. With the continuous development of society, the fire situation is becoming more and more complex and diverse, which brings many difficulties and potential safety hazards to firefighters in the process of fire fighting. In the "11.3" catastrophic fire collapse accident in Hengyang, Hunan Province, 20 fire warriors died bravely. The lesson of blood sounded an alarm for us. At present, leaders at all levels have put the safety of combatants on the fire scene into an important agenda, and are also trying to solve the safety protection equipment of combatants, providing a strong guarantee for the safety of combatants on the fire scene. However, in addition to having good protective equipment on the fire, our combatants' awareness and action of self-protection are also necessary conditions for "preserving themselves and destroying the enemy". The author combines some of his own fire experience and draws lessons from some of his experience, and puts forward some opinions on the safety requirements of combatants' fire action

I. before entering the fire scene, the combatants should wear complete battle clothes and other equipment. When entering the combustion room with large smoke volume and good sealing of burning objects, and entering the system test state, basement, toxic gas existence and other places, they should wear air respirators, and if necessary, they should wear fire-proof and heat-insulating clothes and fire-proof clothes

second, when entering the room with a certain burning time and unclear vision, use the water gun to shoot at the top and around first, hit the ground after hitting the day, and then hit around, so as to eliminate the threat of unstable objects to the combatants, and then attack and extinguish the fire. After entering the room, it is safer to walk or shoot water close to the bearing wall or single wall as far as possible. Because the load-bearing wall is generally not easy to collapse, even if a single wall collapses, it will not be uprooted. Most of it collapses above the middle. That kind of collapse also falls far away, and there will be no major damage at the root of the wall. When entering the burning room on the wooden floor, walk along the wall, probe and walk, and keep the front feet empty and the back feet solid, so as to prevent the floor from collapsing and causing injury

III. when walking on the roof or floor, if you step on the tile strip or other structures, the cracks on the connecting surface should not exceed the rules in the table below. When the body is falling, you should quickly open your arms to both sides, which is conducive to holding the body due to the width of your arms during the falling process, or use your open hands to grasp a support, so as not to cause casualties due to the falling of the body

IV. general fires can be attacked by shooting water through doors and windows. Relying on the existing large coal industrial base is safe and convenient for covering the body and transferring positions

v. when climbing, the fighter should first turn off the water gun, coil the branch hose, and hoist the vertical part. When climbing, two people must cooperate and use safety ropes for protection. Try not to shoot water into the wall or roof, so as to prevent the risk of falling and sliding caused by the reaction of water flow

VI. if the burning point is far away from the parking position, and there is no time to set up a ladder or it is not suitable to set up a ladder, so you can only use the building and its components to climb. When setting up a water gun position to extinguish the fire, you should take the way of riding or stand on your heels. The water belt should try to circle around itself to prevent the recoil force of the water belt from pulling yourself down or falling down

VII. In case of a strong attack under high temperature radiation, water guns must be used for cover. Echelons can be formed to cover when necessary; When it is necessary to close the valve and stop the leakage in a critical situation, the cover water gun should supply water from different water supply routes to prevent injury accidents caused by sudden interruption of water supply

VIII. When fighting flammable gas fires (including domestic liquefied gas cylinder fires), the fight in front of the water separator should be carried out quickly, the laying of water hoses and water supply should be carried out synchronously as far as possible, and there should be a shelter when shooting water to prevent explosion injury

IX. when putting out fires in oil tanks and liquefied petroleum gas tanks, when abnormal sounds are found, the tank body shakes and trembles, and the flame color changes from red to white, which is a sign of oil splashing or gas tank explosion. Combatants should decisively and quickly evacuate the scene to ensure their own safety

X. to put out the fire inside the building, when the depth is more than two watersheds, there must be more than two combatants, and lighting tools must be carried well. It is strictly forbidden to go deep alone, so as to prevent timely rescue in case of unexpected circumstances.

Xi. When cooling the flammable, combustible liquid tanks (barrels) and combustible compressed gas cylinders lying in the combustion area, which can be from raw materials to equipment suppliers, the water gunner should be located at the waist of the tank body, and it is advisable to use flowering jets, It is strictly forbidden to stand at both ends of the tank (generally, the explosion of the tank and barrel is the explosion of both ends), so as to prevent the explosion from injuring people
