The reason of gas explosion

    Gas is flammable and explosive gas and air mixture, reach the explosion limit, meet fire explosion occurred. Want to have a combination of several conditions can blast:

1. The limited space. When gas filled the room, it might explode, so as far as possible when using the open window.

2. The proportion of air. When the gas leakage in the room, and the spatial proportion reaches explosion between the upper and lower limits of might explode. Not much. Also won´t less. Is now in the market the most commonly used three kinds of gas source, the artificial coal gas is the most easy explosion, followed by liquefied petroleum gas, natural gas is relatively safe.

3. Open fires or sparks. Must satisfy the above three conditions to explode at the same time, so the risk of explosion. All kinds of gas explosion limits are as follows: natural gas in the air explosion limit of 5% ~ 15%. The artificial coal gas explosion limit of 5% ~ 35%. Liquefied petroleum gas explosion limit of about 1.5% to 9.5.

Home with the old man must install gas alarm in time.
