A crew comprising of a pipe fabricator and a grinder was deployed for fitment works on a 6” dia pipe at the fabrication yard. The fabricator held the grinding machine for edge preparation, by positioning his right hand over the wheel head and left hand over the dead man switch which is unsafe. As he pressed the deadman switch, the machine moved due to jerk and fell down. While loosing the grip, rotating wheel came in contact with the dorsal side of his right hand middle finger resulting in a cut injury. The fabricator cleaned the wound under water and applied limestone paste as he believed it would help healing the wound. The fabricator informed the Supervisor next day at site office as the wound was aggravated, which was treated as advised by the Doctor. There were lapses in timely reporting of the incident. Why it happened/Finding : The fabricator held the machine in an unsafe manner compromising firm grip on the machine. The fabricator was not in good mental health due to personal reasons back home. Injury got aggravated as they didn’t seek medical assistance immediately and applied limestone paste. The group didn’t report the incident in time considering it to be of minor nature.
