The present paper deals with the location of tanks in a tank farm, in chemical and allied industries. Ideally the tanks are so placed and installed that in case of fire, the neighbouring tanks could remain safe. The safe distance of separation among the tanks is calculated in no wind condition, as well as, in the presence of wind. The paper uses the methods available in literature and modifies the point source model to include the effect of wind vector on the flame height during the calculation of safe inter-tank distance. It is found that for wind velocity > 4. m/s, the modified point source model provides appropriate inter-tank distance. However, for no wind and with wind velocity < 4. m/s, the Shokri-Beyler's method provides safe inter-tank distance. © 2010 Elsevier Ltd.
