A barrel of methylene chloride, also called dichloromethane, a volatile, colorless liquid with a chloroform-like odor. Methylene chloride is used in various industrial processes, in many different industries including paint stripping, pharmaceutical manufacturing, paint remover manufacturing, and metal cleaning and degreasing. The most common means of exposure to methylene chloride is inhalation and skin exposure. It is considered to be a potential occupational carcinogen. Produced by Comochem International, the Italian division of Morton Thiokol company. The Morton Thiokol Chemical Company was an American corporation founded in 1929. It was concerned initially with rubber and related chemicals, and later with rocket and missile propulsion systems. We wonder if the Thiokol Space Shuttle Challenger Disaster that befell in January 28, 1986 – despite prior warnings from engineers – could be in one way or another related to this waste.
