Abstract: On or about June 3, 2015, a lead worker and his helper were demolishing a car wash facility. They had demolished the roof and trusses that covered the first four concrete walls between the first four wash bays. Each wall was approximately 10 feet high and 22 feet long. The lead worker had taken down the first two walls by chiseling out each block one at a time from the top down. However, on the third wall, the lead worker was using a sledge hammer, striking the second to bottom row of block. At approximately 2:30 p.m., the wall fell, pinning him to the concrete floor. He sustained a separated aorta, a ruptured diaphragm, multiple fractured ribs, a fractured pubic bone, and fractured lumbar vertebrae. According to the coroner, the probable cause of death was exsanguination. According to the Orangeburg County Sheriff's office, there was no mechanical equipment or safety equipment on site when they arrived on site to begin their investigation. (OSHA compliance staff was unable to locate the helper to aid in the investigation of the accident.
