Fire and Economic Risk Assessment of Petrol Pumps Within Kathmandu District

: A Service Station is a facility, which sells fuel and lubricants for motor vehicles. The main objective of Petrol Filling Stations (PFS) is to provide fueling facilities for motor vehicles. Kathmandu District holds 102 active filling stations prone to extreme accidents and high explosion potentials. In this study, 27 out of 102 petrol pumps were investigated from the main city core area and other area. Fire risk assessment and economic loss from petrol pumps were carried out in those sampled petrol pumps by the application of the ALOHA (Areal Location of Hazardous Atmosphere) and MARPLOT software, questionnaire, and the related expert’s viewpoints. Petrol pump distribution map was prepared by using GIS model and impact of each parameter in the probability and severity of fire in those filling stations were determined. The fire risk area, that can be affected by fire and explosion was determined, highest area was 2.82Km2 and minimum was 0.63Km2. Total economy of NPRs 53820.85 million likely to be loss in potentially lethal zone if building were fully damaged. Total household affected by fire and explosions ranged from 410-1034 in different locations. Thus, these filling stations need to be well-prepared and planned in case of disaster like fire, earthquake. All the risky aspects must be determined beforehand to prevent catastrophic events in theses pumps. Prompt and urgent improvements, as well as training to the staffs are needed in case of emergency
