A number of online videos show that a huge white mushroom cloud is rising in one place, and there is a constant flicker of fire below, accompanied by a crackling sound. Firefighters are helping nearby, and a white liquid is flowing on the road.

Many residents speculate that lightning and rain lead to the explosion of transformers and natural gas pipelines.

Calcium carbide is extremely dangerous;

Calcium carbide is an inorganic compound, which is a very dangerous chemical as long as it meets water. Calcium carbide is called calcium carbide because it is a white crystal. This industrial product is gray-black, with purple or gray cross-section, similar to stone. But calcium carbide is conductive, and the higher the purity, the better the conductivity, so its name is calcium carbide.

The main danger of calcium carbide is that it does not burn when it is dry, but it can quickly produce highly flammable acetylene gas when it meets water or moisture. When it reaches a certain concentration in the air, explosion disaster may occur and it can react violently with acid.
