Three gas safety in the use of emergency programmes

Winter is approaching, gas sector to remind residents that safety gas. Gas expert reminder: once you have found the gas leak, do not worry, you can contact the gas sector in a timely manner and to ensure that personal and neighborhood safety and property losses. In order to ensure the safe use of gas in winter, the experts in that introduce you to some gas.

First of all to clarify the use of what kind of gas. Because natural gas, coal gas, liquefied petroleum gas three gas composition, properties, in the event of accidents such as running the leakage, the measures taken.

First of all that, the main component of natural gas is methane, it's worse than air, non-toxic, tasteless. In the gas supply for users ease of identification, the gas supply sector into the stench of four hydrogen Thiophene. As long as there is a small amount of gas leakage, people will smell the pungent smell of rotten eggs. Natural gas is easily mixed with air to form an explosive mixture, explosive limit of 5%-15%.

While the coal gas of the main ingredient is hydrogen, methane, carbon monoxide, carbon dioxide and hydrogen sulfide micro. Because it contains hydrogen sulfide, therefore it itself is the smell of rotten eggs. Coal gas, toxic, when people breathe after 7 per cent of carbon monoxide poisoning symptoms appear or even death, coal gas explosion limits 4.5% to 40%.

The main ingredients for liquefied petroleum gas, butane, propane, usually in liquid form stored in liquefied gas cylinders, explosive limit of 2%-9%. Liquefied petroleum gas occurs after you run the greatest risk of leakage. Because it is within the cylinders in liquid, once out of the rapid expansion of after 250 times the moment you will be with the scene; and because it is important to run after the leak is not a stroll up and sink to the ground, gathered in the low-lying, not fat and lower explosive limit.

Use three gas must be careful not to let the gas from leaking pipe or steel, in the event of a leak, be sure not to panic.

Gas leakage to put an end to the open fire. After the gas leak happens to run, because it is larger than the air is light, will soon gather in the upper room, first of all to eliminate the fire stopped quickly closes the pipe, and then open the door and Windows, fans, etc., and fans catch the floats in the kitchen at the top of the natural gas, but do not open the exhaust fan and hood to exhaust air leakage indoor running as prone to electric spark and explosion. Then notify gas company-owned service personnel who come to the Office of timely repair of air leakage.

Coal gas occur after running leak, because of its specific gravity, similar characteristics and natural gas, natural gas should be taken with the same approach. The difference is to prevent poisoning, Access runs the leakage area be sure to wear gas masks, there is no condition, also with a wet towel over your mouth or hold your breath, promptly take measures immediately evacuated.

Liquefied petroleum gas occurs after you run the greatest risk of leakage. Because it is inside the cylinder, liquid flow out will expand after 250 times. Also, because of its major, leakage is not up fluttering but sink to the ground, accumulating in the low-lying, less fat and lower explosive limit, so stop all fires, close the cylinder cut-off valve, open doors and Windows, to use the broom to sweep the ground, the fan run escape of liquid petroleum gas rout out to prevent an explosion fire.
