Maintenance man dies after being drawn into 17 1/2-inch-diameter positive pressure intake pipe - Virginia, August 30, 1992.
Morgantown, WV: U.S. Department of Health and Human Services, Public Health Service, Centers for Disease Control and Prevention, National Institute for Occupational Safety and Health, FACE 92-39, 1993 Mar; :1-6
The case of a 38 year old maintenance man who died after being sucked into a positive pressure vacuum pipe at a paper processing facility was examined. The worker was attempting, with the help of two coworkers, to replace a malfunctioning blower on a vacuum line with a pressure of 3,740 pounds per square inch. Wood chips were transported in the vacuum line over a distance of 300 yards from the milling process into the paper manufacturing facility. The blower was located 10 feet above ground and accessed by a steel grate walkway. The malfunctioning blower had been removed. As the workers began preparing to replace the blower, the victim walked in front of the 17.5 inch open pipe. His chest was immediately pulled against the pipe opening. Two coworkers attempted to pull him away from the pipe, but his body was doubled over backwards and dragged 38 feet into the pipe. The cause of death was massive trauma. It was recommended that comprehensive, written task specific hazardous energy control procedures for each phase of a maintenance operation be prepared and that all workers be completely trained in the operation, that a job site survey be conducted to identify potential hazards and implement appropriate controls, and that employers encourage dialogue and discussion among rotating shift workers so that all are familiar with all hazards.
