Request for assistance in preventing injuries and deaths from metal-reinforced hydraulic hoses.
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, DHHS (NIOSH) Publication No. 93-105, 1993 May; :1-5
This publication was prepared in an effort to assist utility companies, electrical contractors, manufacturers of aerial bucket trucks and hydraulic impact tools, insurers of these companies, electrical lineman, and maintenance personnel in avoiding the hazards of using metal reinforced hoses on aerial bucket trucks near energized power lines. The case of a 37 year old electrical lineman who died when he jumped from a burning aerial bucket and fell 35 feet to the ground was reviewed. At the time of the accident the lineman was sagging the center phase of a three phase, 12,400 volt energized power line. A metal reinforced, rubber hydraulic hose was attached to an impact wrench the lineman was using. The hose simultaneously contacted two phases of the line, and the heat generated caused the hose to melt and rupture. The hydraulic fluid from the ruptured hose ignited on contact with the power line and the bucket became engulfed in flames. He attempted to jump to safety, but caught his foot on the side of the bucket and fell on his head and chest. NIOSH recommends that employers remove any metal reinforced hoses currently installed on any part of the boom, aerial bucket or hydraulic attachments of aerial bucket trucks used to work near energized power lines.
