Abstract: It is well known that the prosecution authorities have started to significantly influence the level of legitimacy in Russia since the very moment those authorities were created. Prosecutors deal with all legal spheres of life activities including fire safety. In the pre-revolutionary Russia fire safety was already controlled by prosecutors along with the issues of national security. The main goal was to inform the authorities about all incidents of fire and fire safety measures. In the pre-revolutionary period all fire safety agencies and organizations were under the supervision of prosecution agencies. The main regulatory and administrative documents of the Prosecutor General of the USSR describe the following directions of prosecution supervision in the sphere of fire safety: supervision of the execution of laws by administrative agencies conducting preventive maintenance and fire safety investigations, control over the execution of orders and instructions and supervision of the execution of laws on responsibility for violation of fire safety rules. Based on this insight into the history, the author of the article makes a conclusion that as an independent activity, prosecutor's supervision over the execution of fire safety rules started to form at the post-socialist period of Russian history.
