Types of accidents on chemically hazardous facilities

Enterprises using in the production process hazardous chemicals potentially dangerous to living next to them the population and the environment, as they may be emergency situations where possible venting of toxic products.

Hazardous chemical – a chemical substance that causes people to cause him acute and chronic diseases, or even lead to its death.
The largest consumers of dangerous chemicals: ferrous and non-ferrous metals (commonly use chlorine, ammonia, hydrochloric acid, acetone cyanohydrin, hydrogen fluoride, acrylonitrile), pulp and paper industry (use chlorine, ammonia, sulfur dioxide, hydrogen sulfide, hydrochloric acid), Engineering and defense (use chlorine, ammonia, hydrochloric acid, hydrogen fluoride), utilities (use chlorine, ammonia), medical industry (based on ammonia, chlorine, phosgene, acrylonitrile, hydrochloric acid), agriculture (use ammonia, chloropicrin , cyanogen chloride, sulfur dioxide).
Sectors of food, especially dairy, refrigerators commercial databases – big consumers of ammonia used as a refrigerant. These potentially hazardous plants includes such seemingly innocuous enterprises as confectioneries, breweries, meat processing plants, dairies, water treatment plants, vegetable base. Ammonia is widely used in agriculture. Thousands of tons of hazardous chemicals are transported daily by various means of transport, is pumped through pipelines. All the above objects of the economy chemically dangerous.

Chemically dangerous object – an object in an accident in which his or destruction may occur mass destruction of people, animals and plants, hazardous chemicals.
Unfortunately, accidents happen at such sites often. Often they are comparable to the scale of natural disasters.

Despite all the measures taken to ensure security, to completely eliminate the risk of chemical accidents impossible.
Chemical accident – an accident on the chemically hazardous facilities, accompanied by a spill or release of hazardous chemicals that can lead to death or chemical contamination of people, food, food stuff and feed farm animals and plants or chemical contamination of the environment.
On the field of chemical accidents are classified as follows (see diagram).

Types of accidents vybrosomavariyno chemically hazardous substances
• Accidents with release of (the threat of discharge) of poisonous substances in their manufacture, processing or storage (disposal)
• Accidents in transport emissions (threatened release) of poisonous substances
• Education and dissemination of poisonous substances in the chemical reactions, which began as a result of the accident
• Accidents with chemical munitions
The main indicator of the degree of danger of chemically hazardous facilities consider the number of people living in the area of ??possible chemical contamination in the event of an accident.
