Proper use of gas, to prevent a gas leak

Gas because of its ingredients contain combustible gas and toxic gases carbon monoxide, have bigger inflammable and explosive dangerous and poisoning. Such as protective gas combustion point is 530 ℃, in the air explosion limit of 20 ~ 74%, the explosion limit of oxygen is 10% ~ 73.6%. When the gas combustion flame, high temperature, easy to spread to spread. Is the main risk explosion gas, the consequences could cause fire, causing damage. There are two main causes of gas explosion:

(l) excessive oxygen content in the gas, or gas into the air from the system.

(2) the leaking gas system. The above two cases can make form explosive mixture gas, with fire and explosion. View of the situation of two kinds of difference is the only one in the gas within the system, one on the outside of the gas system. What are the fire caused by gas explosion? Can cause a lot of fire source gas explosion, according to the characteristics of the gas production and distribution, mainly include:

(l) of various kinds of gas generator hot burning, and burn the red wall. (2) do not meet the requirements of explosion-proof electrical equipment and electrical system sparks. (3) the iron crash, friction sparks; (4) inspection of lighting the fire; (5) a lightning strike, electrostatic, (6) containing sulfur matter spontaneous combustion fire; (7) lighters and matches in the fire of life.
