System for Protecting Against an Unauthorized Control of an a Environmentally Dangerous Production Process
First Claim
1. A system for precluding unauthorized control of an environmentally hazardous technological process comprises means located in premises closed by doors and purposed to automatic stop of a technological process when preset critical parameter values defining hazard of a technological process are reached, the said premise doors being provided with locks comprising timers for delaying closing the doors for a time not less than 8 hours after the time of starting actions for opening them, and the said means for automatic stop of a technological process being provided with energy accumulators for powering the said means for automatic stop of a technological process for at least 8 hours.

Abstract
This invention relates to control systems for technological processes. A system for precluding unauthorized control of an environmentally hazardous technological process comprises means located in premises closed by doors and purposed to automatic stop of a technological process when preset critical parameter values defining hazard of a technological process are reached, the said premise doors being provided with locks comprising timers for delaying closing the doors for a time not less than 8 hours after the time of starting actions for opening them, and the said means for automatic stop of a technological process being provided with energy accumulators for powering the said means for automatic stop of a technological process for at least 8 hours. In the result the reliability of safe operation of a hazardous technological process is improved through precluding a possibility of transferring such technological process to an operation mode with reaching inadmissible parameter values defining hazard of the technological process at a given 8-hour time of subversive control of the technological process.
