In the gas explosion, which led to three people were injured, one of them weak vital signs, is currently being treated in hospital.
Recently, a gas explosion occurred in Harbin City, Daowai District, Binjiang Street Road, Da Fang Fang Li community 225 buildings, unit 4, room 401. After receiving the alarm, Daowai District quickly start the emergency rescue plan, public security, emergency, housing, fire, health, civil affairs, gas, power supply and other departments immediately to the scene to carry out rescue work.
Why does a gas explosion hurt so much?
Gas canisters compared to gas pipelines have natural shortcomings, the building of the gas pipeline will not explode, the relevant design management and maintenance are unified, from the source to avoid pipeline explosions, only because of the sealing of the environment to leak a certain concentration of the fire encountered in the open flame deflagration. Gas tank itself is equivalent to a large pressure cooker, its own repeated use of quality is difficult to guarantee the use of complex environments, the volume of domestic use of a small environment stable pressure is relatively high security, the volume of commercial pressure high use of complex environments, the explosion itself is a huge destructive force, and the explosion of the tank at the same time that the gas encountered in the open flame will again deflagrate, that is to say, blow up twice. Even triggered by the side of the tank to continue to blow, a lot of accidents are the cause of two or more loud noises.
Gas explosion signs?
Of course there are signs, in fact, all kinds of gas are colorless and odorless. So people purposely add low concentrations of mercaptan gases. Farts stink because they contain 0.1 to 0.3% mercaptan. So gas has a bad odor. If there is a gas leak, then most people in an area should feel something.
Who is safer, natural gas or gas?
Explosive limit in terms of the general combustible gas in the air dispersed to the extent of the explosive limit, once there is an open flame ignited easily caused by an explosion. So, if you look at this point of view from the leakage, the higher and narrower the lower line of the explosion limit, the safer, in addition, higher than the upper limit of the explosion limit will not explode. Natural gas: methane-based, the range according to the source between 70% -90%. In general, the approximation of the natural gas explosion limit of 5-15%. Gas: carbon monoxide-based, water gas will contain a certain percentage of hydrogen, the content of different production methods vary. Because it contains carbon monoxide, easy to cause carbon monoxide poisoning. General life with the gas belongs to the coke oven gas approximate 4.7%-37.6%. So relatively speaking, natural gas is safer, liquefied petroleum gas and coal gas is more likely to explode. However, who is not okay leaking gas play, so normal use of no problem, unnecessary because of this change in the type of gas.
