Residents of four districts of Minsk were warned about the possible appearance of green water.
From November 16 in Leninskyi, Zabodskyi, Sovetskyi and Parbomaiskyi, water in heating networks may take on a green tint.
As reported by the Department of Energy, electrical engineers will begin adding fluorescein to the system to look for leaks and test equipment.
The paint will be used until the end of the heating season. The department assured that the material is completely safe for humans and the environment, it is authorized by the Ministry of Health and is used to detect unauthorized use of coolant and test the tightness of water heaters.
