Abstract: On October 4, 2000 Employee #1 was alone in the "hot room" to check whether four 55-gallon drums of MDI (Diphenyl Methane Diisocyanate) had melted so they could be charged into the process for making polyurethane. This is a routine activity that should have taken, at most, a couple minutes. Employee #1 collapsed among the drums which blocked his body from view. The last time he was seen by co-workers was approximately 1:15 a.m. Another employee closed the doors to the "hot room" at about 3:20 a.m. and found Employee #1 at about 4:15 a.m. when the employee returned to check the drums. An investigation was conducted by the county medical examiner the report determined that the cause of death was not occupationally related.
