Abstract: A LOADING PLATFORM EQUIPPED WITH A HINGED GANGWAY (FOR ACCESS TO THE TOPS OF RAILROAD CARS) WAS STRUCK BY A PASSING RAILCAR. THE RESULTING VIBRATION CAUSED A 3 FOOT BY 3 FOOT PIECE OF GRATING TO FALL OUT OF THE GANGWAY. THE GRATING STRUCK EMPLOYEE #2 IN THE SHOULDER. HE LEFT TO SEE THE NURSE WHILE EMPLOYEE #1 REMAINED ON THE JOB, WORKING ALONE. EMPLOYEE #1 WAS FULLY AWARE THAT THE GRATING HAD FALLEN AND STRUCK HIS CO-WORKER, HOWEVER HE CONTINUED TO USE THE LOADING PLATFORM WITH THE MISSING GRATE TO LOAD RESIN. AS HE WALKED ON THE PLATFORM, HE FELL THROUGH THE OPENING, 14 FEET TO HIS DEATH. HE HAD JUST TAKEN SAMPLES OF RESIN FROM THE RAILCAR AND WALKED FROM THE RAILCAR ONTO THE PLATFORM BY WAY OF THE GANGWAY.
