The composition and characteristics of these three kinds of gas are different, and in the event of accidents such as running and leaking air, the measures taken are not the same. To eliminate open fire when natural gas leaks. Natural gas is easily mixed with air to form an explosive mixture with an explosion limit of 5% to 15%. Natural gas after the leak, because it is lighter than air, will soon gather in the upper part of the room, at this time first to put an end to all the fire, quickly close the pipe Jummen, and then open the doors and windows, with fans and other items fan to float in the upper part of the kitchen gas, but do not open exhaust fan and hood, because that is prone
Then inform the gas company's service personnel to come to deal with, in order to repair the leak in time. After the coal gas leaks, it will emit the smell of rotten eggs. Because their specific gravity and characteristics are broadly similar to natural gas, the same approach should be taken to deal with natural gas leaks. The difference is that coal gas is toxic, and when people inhale 7% of carbon monoxide, they develop symptoms of poisoning and even death. Therefore, when the coal gas leak, to prevent poisoning, into the running leak area before you must wear a gas mask.
If there is no gas mask, also use a wet towel to cover your mouth or hold your breath, quickly take steps immediately after the evacuation of the scene. Liquefied petroleum gas (LPG) is the most dangerous after leakage. Because it is liquid in the cylinder, it will expand 250 times times immediately after outflow. And because of its relatively significant characteristics, leakage is not upward fluttering but sinking to the ground, accumulated in low-lying places, not easy to drift and the limit of explosion is low. Therefore, in the elimination of all the fire, close the cylinder Jummen, open the doors and windows, to use a broom fan sweep surface, will run out of the liquefied petroleum gas body drive out to prevent the explosion of fire.
