Cumulative charges are specially modified pyrotechnic explosive devices with the cavity, that is formed in the front part of the brizant explosive charge. During explosion, the cumulative cavity filled with a soft metal insert has considerable cutting and perforating effects. This type of charge is possible to use to extinguish the focus of a very intense flame caused by leak of flammable gas or liquid, if the cumulative cavity is filled with water. With this step, we create a high-pressure water jet of narrow cross section accompanied by a pressure wave, that blows out the intense flame, and water will remove the heat from the epicenter of the fire and prevent it from burning again.
