Construction worker electrocuted in Maryland, April 29, 1987.
NIOSH 1987 Jun; :1-4
A construction worker was electrocuted when the boom of a crane contacted a 13 kilovolt power line. He had been guiding a load attached to the crane when the accident occurred. The company employed 44 workers and was involved in installation of water, sewer, and other underground utility lines. There were no written safety policies. At this job site, workers were installing a sewer line under a highway. Their task was to bore a hole under the highway and insert 57 feet of 36 inch diameter steel casing. The employer had provided a crane with a 15 foot extension. The victim called and requested a boom extension which would provide a potential vertical reach of 35 feet. The employer cautioned the crew that they were working under wire. The crane operator was attempting to position the boring machine correctly, guided by the victim and another laborer. These two had difficulty seeing where the top of the crane was due to sun glare. Both men had both hands on the boring machine when the crane contacted the line. The laborer, wearing rubber work boots, received severe electrical burns on his hands. The victim died of electrocution. It is recommended that employers enforce existing regulations concerning equipment operating near overhead power lines, that employees be trained to recognize hazards, that nonconductive tag lines be used to aid in guiding and stabilizing crane loads, and that additional personnel be used to observe clearances near power lines.
