 Unit VII Case Study 
For this assignment, you are the lead incident commander for a hazardous materials incident similar to those that have been introduced in this course. In this scenario, diisocyanates [toluene diisocyanate (TDI) and methylene diphenyl diisocyanate (MDI)] are being unloaded at the tank farm of HLF Polyurethane Manufacturing. TDI and MDI are used as raw materials in the production of polyurethane. During the unloading process, the vapor return line ruptured and caught fire due to a nearby welding operation that provided the ignition source. 
The following actions were initially taken: 
The evacuation alarm was sounded and the facility emergency response team (ERT) was activated. 
The plant manager and the local fire department were notified of the incident. 
The incident command was established at the facility office near the main access gate to the south (this is the furthest distance within the property boundary from the incident location). 
The incident commander implemented actions required under the approved emergency response plan. 
The ERT was not able to immediately isolate the source of the incident. 
The fire department arrived on location and assumed the incident command of the event.
