Abstract: Between 4:00 and 5:35 p.m. on May 5, 1989, Employee #1 was using a wire brush to strip away paint from metal registers in a large vat containing a stripping solution. He was working alone in a room that was approximately 34 ft long by 14 1/2 ft wide by 8 ft high with no forced ventilation. The stripping solution was GB150 (trade name) and contained about 80 percent methylene chloride, which is known to break down and emit phosgene and hydrogen chloride. Employee #1 was not wearing respiratory protection. He was overcome by solvent vapors resulting in acute toxicity and cardiac dysrhythmia from halogenated hydrocarbons in the solvent. He died.
