Accident: Release of clouds of toxic chemical vaporsMajor damage: 154 people treated, 5 hospitalized for exposure to toxic chemicalsDate: April 12, 2004Place: Dalton, Georgia EVENTS Major Accident Scenario: On April 12, 2004, at approximately 9:30 p.m., a reactor at MFG Chemical's Callhan Road facility in Dalton, Georgia; experienced an uncontrollable reaction during the first synthesis of triallyl cyanurate (TAC) production. The highly exothermic reaction pressurized a 4,000-gallon reactor, causing the manhole to fail and burst. Additionally, the emergency burst disk has been activated. A release of highly toxic and flammable allyl alcohol vapor and toxic allyl chloride was released directly into the atmosphere, exposing and injuring facility employees, nearby residents and emergency responders. [1] Approximately 200 families and local business owners were evacuated, as the reaction continued to release dense vapors. Around 154 people required care and treatment for breathing difficulties and eye and skin irritation. Additionally, five people were hospitalized overnight and one MFG employee suffered minor chemical burns. Pre-Accident Conditions: This event involved three companies: MFG Chemical, Inc. (MFG), GP Chemical (GPC), and Lyondell Chemical Company (Lyondell). MFG was chosen by GPC to manufacture TAC due to the size of the reactor and they had the additional equipment needed for synthesis. The synthesis of TAC requires allyl alcohol and Lyondell is exclusive in the sale and distribution of allyl alcohol. Lyondell requires a visit to a company's facility to ensure and assess the facility's readiness to handle allyl alcohol. After touring MFG's facilities, Lyondell concluded that they would be able to...... middle of document ...... through procedures and recommendations. Lyondell should revise its checklist and place more emphasis on associated allyl alcohol thresholds. EPA Risk Management Program Regulations and OSHA PSM Standard. In addition to the various chemical plants, the State of Georgia also has responsibility for ensuring compliance with the Right to Information Act, which includes reviewing local emergency plans and designating responsibility to an agency. to assist local authorities in obtaining and using risk management plans for facilities.REFERENCESU.S Commission of Inquiry into Safety and Chemical Hazards.
