Abstract: At approximately 9:25 a.m. on August 20, 2013, Employee #1, of Tysons Service Corporation, was working as part of a three-person crew assigned to demolish an existing single-family home. The employer had been contracted to perform the demolition in preparation for the construction of a new home. The work crew had arrived on site at 7:30 a.m. to disconnect the water and sewer lines to the house and cap them off. At approximately 9:25 a.m., the crew was digging a trench the length of the carport in an attempt to locate the sewer line extending from the house. According to the subsequent investigation, Employee #1 apparently was in an unsupported 14-foot 8-inch deep trench and using a probe to locate the sewer line. The trench wall collapsed on top of Employee #1. Emergency services were called. Fairfax County Fire & Rescue responded and found only the victim's left hand exposed above the soil surface. The officer in charge evaluated the scene, pronounced that Employee #1 was dead, and determined that it was now a recovery operation. The Fairfax County Fire & Rescue Department utilized the Technical Rescue Team to recover the victim. Employee #1 was recovered from the trench collapse at 5:15 p.m. on August 20, 2013.
