A laborer, working alone in a vacant store in a shopping mall, died of carbon monoxide poisoning as a result of operating a gasoline-powered, walk-behind concrete saw in an enclosed space. The saw was being used to cut through the concrete floor in order to dig new plumbing trenches. At the time of the incident, the space was not mechanically ventilated and had no natural ventilation. The victim was working with an unlicensed plumbing contractor, who was working for a licensed general contractor. |
