The possibility of individual fire risk reduction when refueling cars at the fuel filling stations using modern technical systems is considered. The network of fuel filling stations is presented as a subsystem of petroleum products provision, which is performing the functions of receipt, storage and release of petroleum and related products (services rendering) to the end users. Hazard is borne by significant amount of stored motor fuel and operating equipment. Possible location of fuel filling stations within the boundaries of the human settlements, as well as the likelihood of manifestation of the subjective factors caused by the inappropriate behavior of the drivers of vehicles or other persons, are additional threats to safety of the personnel and public.

The following types of accidents are typical for fuel filling stations: pool fire, fireball, explosion, pops. The article highlighted the areas of fuel filling stations, where most frequently occur the events, that result in the undesirable consequences. Various scenarios of emergency situations are considered. Pool fire is the most dangerous - scenario of the development of an accident, at which there is a thermal effect on people.

Individual fire risk is calculated. For reducing this risk, it was proposed to supply fuel dispensers with a powder fire extinguishing module. The most efficient way to extinguish the fire is to block oxygen entering to ignition area. Automatic powder fire extinguishing system solves the problem due to the chemical properties of various metal salts that are part of fire extinguishing mixtures. As a result, the introduction of an automatic fire extinguishing system reduces four times the individual risk of people exposure.
