Gas is the main resource used by people now, but the danger is also particularly obvious. Its explosive damage range is particularly large. If the concentration of combustible gas is between the upper and lower limits of explosion, an explosion may occur. Taking propylene as an example, its lower explosive limit is about 2%, and its upper explosive limit is about 1 1%.

The main components of gas in our life are liquefied petroleum gas: ethylene, ethane, propylene, propane, butane and so on. The main component of gas is carbon monoxide (colorless and odorless gas, toxic), and the main components of natural gas are alkanes such as methane, ethane, propane, butane and other trace elements. When these things get together, the explosion between them is unimaginable.

Liquefied natural gas (LNG) has various dangers related to fire and explosion during its storage and supply.

We know that bottled gas is convenient, clean and economical, and has been used in people's lives for a long time, but there are more and more fire accidents caused by gas leakage or improper operation. Once a fire breaks out, the consequences are very serious, from house damage to family damage.

When the gas concentration reaches the explosion limit, even static electricity may cause fire. Any tool that cannot generate sparks, including turning off the lights or turning on any switch, will generate static electricity.

So we need to know how to install gas appliance correctly. Gas appliances should be installed in a ventilated place, the pipeline should not be too long, not exceeding 1.5m, and the joint should be firm. Gas appliance should not be placed in walls, cabinets, pools and other closed facilities. To prevent gas leakage, it is not easy to find it in time, leading to major disasters.
