Approximately 10:42 a.m. on Wednesday, Sept. 10, 1997, an explosion occurred in a resins production unit at Georgia-Pacific Resins, Inc. in Columbus, Ohio. The blast was reported to be felt at least 2 miles and possibly as far as 7 miles away according to various news accounts and other reports. As a result of the explosion, one worker was killed and four others injured. The explosion extensively damaged the plant. Local news reported that a vocational school and several homes and businesses within a 3/4-mile radius were evacuated as a precaution by the local fire department for several hours The explosion also resulted in the release of a large quantity of liquid resin and smaller quantities of other chemicals within the facility. Three fire fighters were injured during the response, treated for first-degree chemical burns, and released. Under a 1997 Memorandum of Understanding (MOU) to investigate chemical accidents and report on the lessons learned, EPA and the Occupational Safety and Health Administration (OSHA) collaborated to analyze the evidence. The purpose of this effort was to understand the circumstances associated with the accident to prevent a recurrence at this and other facilities.
