Water fire, is the use of a powerful water gun emitted from burning objects extinguish the flames, but water can wet surfaces, resistance continued to burn. The law is not applicable to the fire, to a lesser extent the fire. It should be noted the following issues: (1) there should be enough water and water. Small amount of water at high temperature can be decomposed into an explosive combustion of hydrogen and oxygen. Firefighters must stand on the windward side of the fire source and should maintain proper ventilation, return air duct to be clear so that the fire smoke and water vapor into the return air duct discharge; (2) should be surrounded by flames began to fire, and gradually move to fire Source Center, do not spray water directly on fire source center to prevent a lot of steam and hot coals thrown assault, but also to avoid the high temperature thermal decomposition of the moisture source into hydrogen and oxygen; (3) Always check the fire area near the biogas concentration. "Coal Mine Safety Regulations" provides that at the time of the rescue and fire fighting personnel, must designate a person to inspect gas, carbon monoxide, coal dust, gases and other harmful changes in airflow must also be taken to prevent a gas explosion and poisoning of security measures; (4) After Wuhan http://www.whjdny.com/ electrical equipment fire sprinkler lease, you should first turn off the power. Before power is not cut off, use only non-conductive, fire-fighting equipment, such as with sand, rock powder and carbon tetrachloride fire extinguishers. Otherwise, not off the power, direct fire water, water conductivity, the fire will be greater, and endanger the safety of firefighters. In addition, the water can not be used to extinguish oil fires, oil is lighter than water, but not easily mixed with water, the water flow can be expanded with the fire area.
