What is the danger of calcium carbide exploding in water?
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.

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.

Try not to touch them with calcium carbide, because it will damage our skin and cause itching, inflammation, "bird's eye" ulcer, melanosis and other diseases. If you accidentally touch them, you must immediately take off the contaminated clothes, rinse them with plenty of running water for at least 15 minutes, and then seek medical attention. Skin burns are characterized by long-term unhealed wounds and chronic ulcers. If exposed to workers, there will be symptoms such as less sweating, damaged enamel and increased incidence of dental caries, so the risk is very high.

When working in a factory, we must pay attention to the use of calcium carbide, and we must not neglect every step, otherwise it will lead to devastating results. For example, a factory worker put an electric bucket on the ground and kicked it, then it suddenly exploded and hurt his leg. This is because the calcium carbide in the calcium carbide bucket will absorb the water vapor in the air when it is crushed and poured into the bucket. At this time, the surface of calcium carbide is wet, so an explosive mixture of acetylene and air is formed in the barrel. Because calcium carbide contains ferrosilicon, it collides with the barrel iron sheet, causing sparks to ignite explosive mixture, which leads to a big explosion, which is very dangerous.

In order to avoid these hazards, we should store calcium carbide in a cool and dry warehouse before use. Pay attention to the operation steps when using, avoid physical contact, and store it separately from other chemical reagents to avoid mixing.
