Oncor Electric repair crews were called to a Hurst neighborhood after a report that a tree trimmer fell into power lines.
The incident was reported to have occurred on the 3100 block of Oakview Drive, north of state Highway 26 near Precinct Line Road.
Officials said a tree trimmer sustained burns to the hands while working in the area. The worker was taken to Parkland Memorial Hospital in Dallas in an unknown condition.
Oncor reported power was out to approximately 45 customers for a short time; service has since been restored.
