The author of the article discusses the procedure and logics of filling in input data by the user in accordance with the interface of the developed readiness assessment program, regulated working hours and the number of employees involved in the technical maintenance of gas detectors, which is proposed for implementation in the information subsystem of the automated system for preventing fire and explosion hazards. The urgency of the problem of reducing the probability of response of gas detectors thermochemical sensors due to the effects of catalytic poisons and other negative factors of the production environment is noted. To solve this problem, the process of estimating labor costs in time terms is described as well as modeling the regulated number of sensors and the composition of maintenance teams at real refinery facilities. It was established that the use of the developed program allows for a more accurate calculation of the number of sensors required in accordance with TU-gaz-86 and the number of personnel required for their maintenance, which in turn will help to compare it with the actual number of sensors installed at the facility.
