What Is Chlorine Gas?

Chlorine, with the chemical formula Cl. It is yellow-green under normal temperature and pressure. It is a highly toxic gas with strong pungent odor. It is suffocating, has a higher density than air, and is soluble in water and alkaline solutions. It is easy to compress and can be liquefied into yellow-green oily liquid chlorine. It is one of the main products of the chlor-alkali industry and can be used as a strong oxidant.

According to statistics, more than half of the turnover of the chemical industry in the early 1990s was related to chlorine; about 1/4 of the chemical industry personnel were engaged in chlorine-related activities. The amount of chlorine used in the chemical and pharmaceutical industries accounts for about 75% of its total output. Among the top 50 chemical products produced in the United States in 1993, the output of chlorine was second only to sulfuric acid, nitrogen, oxygen, ethylene, quicklime, ammonia, and sodium hydroxide, ranking eighth. Since the 1960s, chlorine production in a country has often been regarded as an important indicator of the level of development of the chemical industry.

Chlorine events

At 19:00 on the evening of April 15, 2004, due to the outdated chlorine tank and related equipment, a chlorine gas leak in the Chongqing Tianyuan Chemical Plant caused an explosion of the sewage tank; at 5:57 pm on April 16, relevant personnel of Chongqing Tianyuan Chemical Plant Illegal operations in handling chlorine gas leakage accidents caused explosions in the liquid chlorine gas storage tank. Nine people were killed, three were injured and 150,000 people were evacuated.

At 1700 hours on April 12, 2016, a chlorine leak occurred at a waste acquisition station in Lintong County, Shanxi Province. Dozens of elementary school students in a nearby primary school subsequently developed symptoms of breathing discomfort and abdominal pain and were sent to Lintong County People's Hospital. receive treatment.

Since May 2002, our province's fire brigade has successfully dealt with more than 20 fire accidents caused by chlorine leaks and leaks. On May 28, 2002, the chlorine gas leak of Jinchang Company of Huangshi Mining Bureau, the fire brigade successfully disposed and evacuated more than 2,000 households, about 6,400 people; on November 6, 2003, chlorine gas at Dongfeng Paper Mill, Jianjian Street, Qiaokou District, Wuhan City The storage tank (capacity of 1 ton) leaked. The fire brigade rescued more than 200 people from the scene, successfully plugged the leak and safely transferred the storage tank. ^[7]
