NAICS industry code: 238110

On 6/3/2017, an employee was working in a trench to erect a retaining wall to insert a large machine. During the work process, the concrete company had to remove the trench walls so that the work crew inside the trench could apply mortar to a pre-set area where the cinder blocks were to be placed. As the concrete crew removed the walls, the side of the trench collapsed and toppled onto the injured employee. He suffered forehead lacerations and bruising and temporarily lost consciousness. He was hospitalized.
