The water gunner is a front-line combatant who is directly at the front of the fire and directly connected with the short fire. It is also one of the key figures in determining the success of fire fighting. "Save yourself to better destroy the enemy", whether the combatants are safe on the fire or not, also determines the success or failure of the fire fighting. With the continuous development of society, the fire scene situation has become more and more complex and diversified, which brings many difficulties and hidden safety hazards to firefighters in the process of extinguishing fires. The collapse of the "11 · 3" huge fire in Hengyang, Hunan, where 20 firefighters died bravely. The lesson of blood sounded the alarm for us. At present, leaders at all levels have put the safety of combatants on the fire field on an important agenda, and they are also working hard to solve the safety protection equipment of combatants, which provides a strong guarantee for the safety of combatants on the fire field. However, in addition to good protective equipment, our combatants have their own safety protection consciousness and actions on the fire, which is also a necessary condition for "preserving ourselves and destroying the enemy". The author combines some of his own fire field experience and draws on some of his experiences to put forward a little insight on the safety requirements of combatants' fire field operations.

1. Combatants must wear combat suits and other equipment before entering the fire. They must wear air breathing apparatus when entering combustion rooms with large smoke and good sealing properties, basements, and the presence of toxic gases. Always wear fire-resistant thermal insulation clothing and fire protection clothing.

2. When entering a room with a certain burning time and unclear vision, use a water gun to shoot upwards and around, first hit the sky, then hit the ground, and then hit the surroundings 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 near the load-bearing wall or single wall. Because the load-bearing wall is generally not easy to collapse, even if the single wall collapses, it will generally not be uprooted. Most of them collapse above the middle. Such collapses also fall in the distance, and there will be no major damage at the root of the wall. When entering the burning interior of the wooden floor, walk along the wall, walk, keep the front foot empty and the back foot solid, to prevent the floor from falling and causing injury.

3. When walking on the roof or floor, such as stepping on a tile or other structure, when the body is falling, you must quickly open your arms to both sides, which is conducive to resting your body due to the width of the two arms during the fall , Or use an open hand to grab a bracket to prevent the body from falling and causing casualties.

4. General fires can be attacked by spraying water through doors and windows, which is safer and more convenient for covering the body and shifting positions.

5. When ascending a combatant, the combatant should first turn off the water gun, the feeder hose should be coiled, and the vertical parts should be hung well. When ascending the height, two people must cooperate and use a safety rope to protect. Try not to shoot water toward the wall or roof to prevent the risk of falling or slipping caused by the reaction force of the water flow.

6. If the burning point is far away from the parking place, you can only use the building and its components to climb and set up a water gun position for fire extinguishment. Try to make a circle around yourself to prevent the recoil of the hose from pulling or falling.

7. A strong attack under high-temperature radiation must be covered by a water gun. The echelon cover net can be formed when necessary; when the situation is critical and the valve must be closed to stop the leak, the cover water gun should supply water from different water supply routes to prevent accidents caused by the sudden interruption of the water supply.

8. When fighting flammable gas fires (including domestic liquefied gas cylinder fires), fight before the water divider should be fast, the hose laying and water supply should be synchronized as much as possible, and there should be a shelter when shooting water to prevent the explosion from hurting people.

9. When extinguishing the fire of oil tanks and LPG tanks, when abnormal sounds are found, the tank body shakes and trembles, and the flame color changes from red to white. This is a sign of oil splashing or gas tank explosion. Combatants must be decisive and rapid. Withdraw from the scene to ensure your own safety.

10. To fight fires inside buildings, when there are more than two hoses deep, the combatants must have more than two people, and they must bring lighting tools. It is strictly forbidden for one person to go deep, to prevent timely rescue when other situations occur

11. When cooling flammable and combustible liquid tanks (barrels) and combustible compressed gas cylinders lying in the combustion area, the water gunner should be located at the waist of the tank body, and it is appropriate to use flowering jets. It is strictly forbidden to stand on both ends of the tank (generally The explosion of cans and barrels is bursting at both ends) to prevent the explosion from hurting people.
