A Hoschton, Ga., electrician died today after he was struck in the face by a live wire in front of a Martinez residence.

Workmen survey the scene Thursday after a co-worker was shocked by electricity. William Bret Ward, 45, was hit in the forehead by a live wire at about 10:30 a.m. while working on a ground transformer at a home on the 3900 block of Braddock Street, Columbia County Coroner Vernon Collins said.

“(He) was pulling a wire into it and apparently his head came in contact with the current, and it electrocuted him,” Collins said.

Ward, a worker with Utility Lines Construction Services Inc., was wearing protective gloves and rubber sleeves when the wire hit him, Collins said.

Ward’s co-workers performed CPR on him until Martinez-Columbia Fire Rescue and EMS crews arrived at the scene.

“It was just too much for him,” Collins said.

Ward was pronounced dead at about 11:30 a.m. at Doctors Hospital.

Worker Hurt in “Manhole Explosion” Probable Arc Flash

Three primary causes for “manhole explosions” are
1. Ignition of combustible or flammable gases or dusts in the manhole
2. Arc Flash
3. A combination of the two.
By law, gases are monitored and these explosions are fairly rare.  Arc flashes are more common when gases are being monitored.

PP&L Network worker burned in arc flash/transformer issue. Wrong PPE here would have been a fatality.

Posted by Hugh Hoagland
Filed under Arc Flash/Shock Safety, Electric Utility Incidents, Underground Network Incidents | No Comments

PP&L has been in arc rated clothing for years.  They, like most electric utilities in the US have a strong arc flash program in place.  In cotton clothing, this worker would likely have never lived.  The right stuff makes a difference but doesn’t always full protect.
The NESC (National Electrical Safety Code) 2007 version requires utilities to [...]

These happen. If workers are present they must be protected by some means. ConEd uses arc rated clothing (ASTM F1506) and rubber gloves with leather protectors to start and arc flash blankets (ASTM F2676) in some cases. They use NESC electrical safety training for their arc flash training
