The human element of the system has one of the biggest potentials for either causing or preventing an accident. Safe job performance by operating, maintenance personnel and contractors has a tremendous positive impact on safety. The Permit System is an important element of safety management system and implementation of this in true spirit shall help in ensuring a safe working environment, thereby reducing the possibility of injury to personnel, protect property, and avoid fire, explosion & adverse effect on the environment. A permit-to-work system is a formal recorded process used to control work which is identified as potentially hazardous. It is also a means of communication between site/installation management, plant supervisors and operators and those who carry out the hazardous work. Essential features of permit-to-work systems are clear identification, training and standard control measures. In this thesis various types of work permit systems such as confined space entry, hot work permit, excavation permit, radiation permit, electrical isolation and work at height permit are discussed. The methodology to develop a new effective work permit system is also given.
