A METHODOLOGICAL APPROACH TO INTERNAL ANTIFIRE CREW OPTIMIZATION - ANOIL REFINERY CASE-HISTORY

This paper deals with the problem of defining the operational tasks, m odelling and optimizing of antifire crew and their attempts. Unwanted events are generally modest and easily controlled in their starting ph ase. This obviously leads to considering that quickness and coordinati on enhance the possibility of successful fire control. Hence the impor tance that the first intervention of the factory antifire crew is supp orted by strong organization and efficiency. Immediate and appropriate response to emergency is essential to minimize severity of accidents, life losses, as well as the potential reduction in the plant future p roductivity. In approaching internal antifire crew optimization, it is convenient to distinguish a traditional inventory phase, a subsequent optimization and a graphic modelling phase. Optimization criterion is developed according to graph theory, with regard to intervention path ways and to consistency of antifire crew. The proposed graphic model p rovides, in an immediately readable way, the sequence of operator acti ons to be followed in order to cope with emergency situations. (C) 199 7 Elsevier Science Ltd.
