Waste Site Cleanup & Reuse in New England
On the morning of July 18, 2012 EPA was notified about a potential release inside a chemical storage and production room at a fragrance manufacturing facility in Danbury. A bulging drum had been discovered several hours earlier and reported to the Danbury Fire Department and the Conn. Dept. of Energy and Environmental Protection. Concerned about a potential release or explosion the state department asked EPA for technical advice on a run-away chemical reaction in a 55-gallon steel drum. The reacting chemical was reported as Pparglev Propargyl Acetal.
The bulging drum was in a room with other secured chemicals including: flammables; water reactives; corrosives, and chemicals with vapors heavier than air. The room had an air scrubber system that had stopped running at least once that day because of lapses in electricity caused by thunderstorms. Neighboring buildings were evacuated and the road in front of the facility was closed.
EPA arrived at 2:30 pm and worked with the state, town officials and plant employees to assess the situation. By 3:30pm temperatures were slowly decreasing in the drum from an initial reading of 199 F. A second bulging drum was found, however, next to the first drum with a high and increasing temperature. According the plant’s operator, both drums were bulging from the same unknown reaction.
An EPA chemist believed there was a risk of fire if a drum burst and an ignition source was nearby. Crews checked the temperature of the drums hourly to determine whether the reaction was still occurring. By 8:40 pm, temperatures were returning to room temperature and the reactions were apparently ending. At 10 pm, both drums were punctured without a release of liquid. After the drums cooled overnight, the plant operator packed the drums to be transported for disposal.
Location: 21 Finance Drive, Danbury, Conn.
