Fire safety in tanks of oil and oil products storage

The design of tank farms, providing them with fire protection and actions of fire and rescue units during fires or emergencies at such facilities are regulated by a number of regulations, despite the strict fire safety measures at these facilities, the number of fires in the parks storage of oil and oil products has remained unchanged for the last decades. Purpose of the article – is to develop on the basis of modernization of the existing system of fire protection of tank farms a methodology of automated water supply system for cooling tanks and formation of a fire-resistant self-tightening film for fire extinguishing with the help of a foam generator. Conclusion. The proposed sublayer fire extinguishing system provides rapid fire extinguishing by forming a fire-resistant self-tightening film on the surface of the oil product by floating in the upper part of small bubbles of low-density foam, blocking the access of oxygen to the combustion zone. The use of permanently installed in the upper belt of the tank pipelines for intensive water cooling of its walls in the event of a fire allows you to automatically perform water cooling of the tank walls without the use of gun barrels. The application of the proposed measures for fire localization makes it possible to reduce the damage from the fire by about 30… 36% compared to the generally accepted approach. The system of fire safety of facilities with the presence of petroleum products must contain a set of measures that exclude the possibility of not exceeding the values of the permissible fire risk and aimed at preventing the danger of fire and creating conditions for its successful extinguishing.
