Abstract: At approximately 09:30 a.m. on January 4th, 2011, an employee of an underground utility line installation contractor was helping a backhoe operator dig a trench for the installation of a sewer lateral line. The bucket of the John Deere backhoe contacted an unmarked 16KV power line and caused a short, which resulted in a flash fire. The employee received second and third degree burns to the face. The work area and boundaries of the project were not properly marked by the construction company and no proper project address was provided to the company which locates and marks the subsurface installations. The injured employee was transported to Los Robles Medical Center, where he was treated. At the time of the accident, the injured employee was working for the company for almost one year performing duties of a laborer. The employee's supervisor was on site at the time, but did not witness the accident. The Division was notified of the accident on January 4th 2011 at 11:14 a.m. by Ventura County Sheriff Department and initiated an inspection on January 4th 2011. Interviews were conducted of the injured employee's supervisor, the injured employee, and the backhoe operator. The investigation concluded that a violation of CCR Title 8 Sec:1541(b)(A)(1) was the cause of this accident, as the excavation area was not properly delineated by the company as specified in Government Code Section 4216.2. As a result, the Division issued a Serious non-accident related citation to the employer for CCR Title 8 Sec:1541(b)(A)(1) due to the fact that the accident did not result in a serious injury as defined by LC6302.
