Design of automated fire and safety system in tanks and vessels

Abstract

A literature review has been conducted to gather information related to the extinguishment of actual tank fires and relevant large-scale fire extinguishing tests. The aim was to search for data that could be used for validation of foam spread models. In total, 480 tank fire incidents have been identified worldwide since the 1950s and the information collected has been compiled into a database. A list of the incidents with some data is provided in this report. Out of the 480 fire incidents, only about 30 fires have provided relevant information for model validation. A more detailed summary of the existing data from these fires is also provided in this report. Looking to this history it was very necessary to timely trigger the fire system so that it is never too late and the situations are not out of control. Keeping this in mind Gayatri Tanks & Vessels gave us a project on this particular topic of fire and safety simple automation in tanks and vessels. This report consists a brief about the system using PIC controller as the brain of the system. Different foams are explained so as to give an overview of which type of foam is to be used according to particular situation. The system is supposed to detect a fire inside the tank as well as to the vicinity of the vessel and activate the valve so that the system starts to function.
