The reliability of oil pipeline transport equipment determines not only economic efficiency but also the level of fire safety of infrastructure facilities. Corrosion damage, especially microbiologically influenced corrosion, is one of the main causes of pipeline and shut-off valve depressurization, leading to the leakage of flammable liquids and gases and the formation of explosive and fire-hazardous zones. The article demonstrates that the activity of sulfate-reducing bacteria not only initiates local metal destruction but also generates hydrogen sulfide – a toxic, flammable, and explosive gas capable of changing the fire and explosion hazard category of a facility. Based on experimental data and regression modeling, an approach to evaluating the effectiveness of inhibitor protection is proposed, which reduces the corrosion rate and, consequently, the probability of fire occurrence.
