by burning must have some basic conditions that the basic principle is to destroy the fire to stop the combustion reaction of the combustion conditions. The basic principle for the following four aspects:
some of the following chemicals:
is the alkali metal elements in the periodic table of the elements of metal elements in the first column, referred to as lithium, sodium or potassium or rubidium or cesium, francium. This kind of metal is very active in chemical property, oxygen in air at room temperature and can react violently burning under the condition of heating, and water will rapidly react to form hydrogen and release a lot of heat, even igniting the hydrogen explosion.
; calcium carbide calcium carbide chemical name (chemical formula CaC2), white crystal, industrial products for the black block, is an important basic chemical raw materials, mainly used to produce combustible gas acetylene, non combustible, but in response, severe water acetylene and release a lot of heat. Acetylene is easy to react with oxygen in the air to release a lot of heat.
chemical formula C6H15Al or Al (C2H5) 3. Colorless liquid, mainly used in organic synthesis, also used as rocket fuel. Chemical nature of the active, can be in the air in spontaneous combustion, the reaction of water to produce a combustible gas and emit a lot of heat, will cause the explosion.
is common gasoline, kerosene, vegetable oil and benzene in the kitchen, such items as the nature of a lower density than water and insoluble in water, burning if put out with water and often ineffective and even lead to the spread of fire. If a small amount of vegetable oil in the combustion available lid off. />
above the part of the water to fight the fire of chemicals, because of the special nature of these chemicals, fighting methods are very complex. If there is a fire in the warehouse for such chemicals, it must be the first time to notify the fire department, and to inform the type and quantity of the chemicals stored.
