Many different jobs require climbing, and most workers in Tennessee and across the nation are protected by safety regulations that require them to have safety equipment like harnesses. Until recently, however, federal regulations have allowed electrical workers to not use safety equipment when climbing. Instead, they have been allowed to "free climb" without any kind of safety equipment.
The Occupational Safety and Health Administration has recently announced that it is banning the practice of "free climbing" by electrical workers. Employers will be required to protect electrical workers with the necessary safety equipment, and they have until April 2015 to meet the terms of these new regulations.
