1. At normal temperature and pressure, liquefied gas is in a gaseous state; when mixed with air, it can be easily ignited by even the smallest spark. Liquefied gas has a low lower explosive limit in air, and any leaked liquefied gas will quickly form an explosive mixture within a certain area. In a kitchen with a volume of 6 m3 and doors and windows tightly closed, even a leakage of 0.12 m3 of liquefied petroleum gas can lead to an explosion if exposed to a flame. Even if the leakage is less than 0.12 m3, since liquefied petroleum gas is heavier than air, it does not disperse easily, forming flammable mixtures near the ground, which is also quite dangerous. 2. Liquefied gas is volatile; liquid liquefied petroleum gas vaporizes rapidly at normal temperature and pressure, absorbing a large amount of heat in the process. Therefore, once liquid liquefied gas leaks and comes into contact with the human body, it can cause frostbite. 3. When the concentration of liquefied gas in the air reaches a certain level, it can cause people to feel dizzy; in severe cases, it can even be fatal.
1. Asphyxiation； 2. Poisoning ； 3. Explosion ； 4. Frostbite ； 5. Cause fires.
Risk of explosion, fire. Risk of frostbite. Risk of poisoning
Frostbite-like, burning, volatile,
Flammable and explosive; absorbs a large amount of heat upon vaporization, can cause frostbite; contains certain amounts of sulfur and nitrogen compounds, which can lead to poisoning
Liquefied petroleum gas poses a risk of combustion and explosion due to its properties of being easily expandable, easily vaporizable, and prone to generating static electricity; it also presents risks such as corrosion and other harmful effects.
When mixed with air, it can form an explosive mixture that is highly prone to combustion and explosion in the presence of open flames or high temperatures. It undergoes violent chemical reactions with fluorine, chlorine, and others. Its vapor is heavier than air, allowing it to spread over considerable distances at lower levels; it can catch fire and reignite when exposed to an open flame. In the event of high temperatures, the pressure inside the container increases, posing a risk of cracking and explosion. Contact of liquefied petroleum gas with the skin can cause severe burns.

Liquefied gas has a low lower explosive limit in air, and any leaked liquefied gas will quickly form an explosive mixture within a certain area. In a kitchen with closed doors and windows and a volume of 6 m3, as long as 0.12 m3 of liquefied petroleum gas leaks out, it will explode upon contact with an ignition source ； Even if the amount of leaked liquefied gas is less than 0.12 m3, since liquefied gas is heavier than air and does not spread easily, it can form a flammable mixture near the ground, which is quite dangerous. 2.
