Physical and Chemical Properties of Methylene Chloride Essay

Physical and Chemical Properties of Methylene Chloride - Essay Example The term â€Å"hazardous substance† means any substance or mixture of substances which is toxic, corrosive, an irritant, a strong sensitizer, is flammable or combustible, generates pressure through decomposition, heat or other means, if such substance or mixture of substances may cause substantial personal injury or illness during or as a proximate result of any customary or reasonably foreseeable handling or use, including reasonably foreseeable ingestion by children.2 According to the Occupational Safety and Health Standards of the United States Department of labour, employees exposed to methylene chloride are at an increased risk of developing cancer, adverse effects on the heart, central nervous system and liver, and skin or eye irritation.3 Possibly hazardous short term degradation products are not likely however, long-term degradation products may occur. The products of degradation are more toxic. There is no disturbance or aerobe purifying process at concentrations less than 200 mg/l. Methylene chloride is a stable and non-corrosive chemical in the presence of glass. It is combustible at high temperatures, with an auto-ignition temperature of 556 oC (1032.8 oF). When using methylene chloride, avoid the following: strong acids, alkali metals, and oxidizing agents. In case of fire, use water spray, fog or foam. Do not use a water jet. Fire may liberate toxic and corrosive vapours. In case of skin contact, immediately flush skin with plenty of water. Cover the irritated skin with an emollient. Remove contaminated clothing and shoes. Thoroughly wash and clean shoes before reuse. If it is serious skin contact, wash affected area with disinfectant soap and cover with anti-bacterial cream. Seek medical attention immediately If ingested, avoid inducing vomiting, unless directed to do so by medical personnel. Never give anything by mouth to an unconscious person. If large quantities have been swallowed, call a physician immediately. Loosen tight clothing such as a collar, belt or tie.
