The Sanitary Protection Zone (SPZ) is a special area with a special regime of use, which is established around objects and industries that are sources of impact on the environment and human health. The size of the sanitary protection zone ensures the reduction of the impact of pollution on the atmospheric air (chemical, biological, physical) to the values established by the hygienic standards. In accordance with the Urban Planning Code of the Russian Federation, it is impossible to obtain a construction permit and / or an act of commissioning an object without an agreed project of the sanitary protection zone. According to the sanitary classification, all enterprises are divided into 5 hazard classes. Each hazard class has its own SPZ size - from 1000 m to 50 m.

INEX evaluates the sanitary classification of each projected facility and develops a design for a sanitary protection zone.
