SPECIFICS OF DETERMINING THE VALUE OF AN INDIVIDUAL FIRE RISK FOR THE STAFF OF AN OIL-TANKER RESERVOIR PARK
INTRODUCTION. The situations when fire safety requirements are carried out, but there are some deviations from normative documents are rather widespread. For this reason, fire risk assessment for an object is obligatory to provide fire safety. The article deals with a normative algorithm for determining the value of an individual fire risk using an oil-tanker reservoir park as an example. MATERIALS AND METHODS. The statistics data on fires and accidents, specifics of different accident and fire development scenarios have been analyzed, the probabilities of dangerous accident outcomes have been determined, their consequences have been assessed. RESULTS. An individual fire risk for the staff is a probable human death caused by dangerous fire or explosion factors. It takes into account the probability of the physical presence of a human in a specific place. To determine it, one should know the presence time distribution for the staff in the territory of an object by analyzing equipment maintenance modes, patrol schedules, etc. For example, zones located near each reservoir are characterized by the presence of the staff for 20 minutes a week (0,048 h). Consequently, in these zones workers are present with a probability of 2·10-3 per day. In other zones (outside the buildings), the staff presence time is 5 minutes per day, i.e. the probability of the staff presence is 8,3·10-2 per day. CONCLUSION. Having assessed the individual fire risks in the territory of an oil-tanker reservoir park, we have found out that fires and explosions after the destruction of reservoirs accompanied by oil spilling are significant dangers. Accident development scenarios are as follows: fires and explosions (fire-flames). In general, the individual fire risk complies with a regulatory risk and the object is protected from fires.
