In Tatarstan, cases of citizens' appeal, that some persons under the guise of EMERCOM employees in civilian clothes walk around apartments and houses of citizens and ask to open doors, ostensibly, for carrying out of inspection of houses for keeping fire safety, while offering to purchase and install autonomous fire detectors or gas leakage sensors, have become more frequent. EMERCOM does not carry out entrepreneurial activity on sale of any equipment to citizens, including fire-fighting.
