**Investigation Nr**

**Event**

At 6:30 p.m. on October 25, 2017, an employee was working with a crew that was engaged in sewer line rehabilitation work using a cured-in-place-pipe (CIPP). The CIPP process is a trenchless method for the sewer pipe repair which involves a resin-impregnated fiberglass liner inverted into the damaged sewer pipe.  The employee crawled into a 24 inch horizontal sewer line and was in approximately 30 feet, cutting ropes and lying flat hot water circulation hoses.  The employee began to mumble and became unresponsive.  Emergency Services responded and the employee's body was recovered by the Fire Department Rescue Team and the employee was pronounced at the scene.  Drowning with styrene toxicity was listed as a significant contributing factor.
