Abstract: At approximately 11:23 p.m. on January 25, 1994, paramedics from the Wake County Emergency Medical Service arrived at the Winn Dixie grocery warehouse and evaluated Employees #1 through #7 who had been working in the old portion of the warehouse and were complaining of headaches, nausea, and dizziness. Employees #1 through #7 were taken to Wake Medical Center where they were treated for carbon monoxide poisoning. Employee #1, a janitor, was admitted for further evaluation. He had been polishing the floor in the employee break room prior to becoming ill. The cause of the accident was inadequate ventilation in the warehouse, which allowed the accumulation of carbon monoxide generated by 17 propane forklifts (Hyster model S40XL). Four of the 17 forklifts were identified by the employer's technical support for the machines, WrenHandling, Inc., as being in a poor state.
