In this paper, risk priority factor of an industrial problem were discussed. In Ashok Leyland, Ennore unit engine assembly in the H-cylinder, all the components from various shops will be brought here and assembled by the workers. These workers stay at each station. There is a roller slider like conveyor running through all the stations. Initially the engine block is clamped on a tray at the first station, this tray travels on the sliders throughout the station. There are twenty two trays lined up on the sliders and the components are fixed on the engine block at each station by the workers. These trays have rollers mounted under it so that it moves freely on the slider. There is possibility of collision of the trays against each other when it moves from one station to another. Also these trays moves freely on the sliders while the components are being fixed, as a result it is difficult for the workers to ensure grip while screwing and doing other works. Right now they use the help of others to hold the tray while fixing critical components like flywheel and fuel injector. In addition to this the production time is also affected. In this paper, how to prevent the accident in industry by calculating RPN for fabrication and assembly to ensure safety of labours were discussed.
