Abstract

This pap& presents the quantitative risk assessment for the storage of titanium tetrachloride (TiCl,).It is the major reactant used for the production of titanium in the titanium sponge
plant. Titanium tetrachloride readily reacts with moisture, leading to the release of toxic hydrogen chloride (HCI).F ire explosive and toxicity index analysis, and hazard and operability
(HAZOP) studies for the entire titanium sponge plant were carried out. Based on these studies, the TiCl, storage section was found to be one of the most hazardous sections in the titanium
sponge plant. Fault tree analysis technique has been used to identify the basic events responsible for the top event occurrence, ie, release of HCl due to the hydrolysis of TiCl, upon contact
with moisture in the environment during spillagelleakage of TiCl, from the storage tanks and to calculate its probability. Consequence analysis of the probable scenarios has been carried
out. The risk has been estimated in terms of fatality.and injuries. Based on these results, basic input in the form of recommendations for possible changes in the design and operation of the
titanium sponge plant have been made for the risk management.
