1,1,2-trichloroethane

1,1,2-trichloroethane is an organochlorine compound with the molecular formula C2H3Cl3 and CAS number 79-00-5. This chemical substance has a molecular weight of 133.4 g/mol and belongs to the family of chlorinated hydrocarbons. It is classified as a suspected carcinogen (Carc. 2) and presents acute toxicity hazards, requiring careful handling and safety measures in industrial applications.

1,1,2-trichloroethane is a colorless liquid at room temperature with a characteristic sweet, chloroform-like odor. It has a boiling point of approximately 114°C and a density higher than water. The substance is moderately soluble in water and miscible with most organic solvents including alcohols and ethers, making it useful as a solvent in various industrial processes.

1,1,2-trichloroethane is primarily used as an industrial solvent and intermediate in chemical synthesis. It serves as a degreasing agent for metal parts, a solvent for adhesives and coatings, and an intermediate in the production of other chlorinated compounds. Due to its carcinogenic classification and toxicity, its use has become increasingly restricted and regulated in many applications.

1,1,2-trichloroethane must be handled with appropriate personal protective equipment including chemical-resistant gloves, safety goggles, and respiratory protection when necessary. Work should be conducted in well-ventilated areas or under fume hoods to prevent inhalation exposure. Given its carcinogenic classification (Carc. 2) and acute toxicity, minimize skin contact and vapor exposure through proper engineering controls and safety procedures.

1,1,2-trichloroethane should be stored in tightly sealed containers in a cool, dry, well-ventilated area away from heat sources and ignition points. Keep containers away from incompatible materials such as strong bases, aluminum, and magnesium. Storage areas should be equipped with appropriate spill containment measures and emergency equipment. Ensure proper labeling and access restriction to authorized personnel only.

1,1,2-trichloroethane exposure requires immediate action depending on the route of contact. For skin contact, remove contaminated clothing and wash thoroughly with soap and water. In case of eye contact, flush with clean water for at least 15 minutes. If inhaled, move to fresh air immediately. For ingestion, do not induce vomiting and seek immediate medical attention. Always consult emergency services for serious exposures.

1,1,2-trichloroethane must be disposed of as hazardous waste through licensed waste management companies in accordance with local and European regulations. The substance cannot be disposed of in regular waste streams or sewage systems due to its toxicity and environmental impact. Waste containers should be properly labeled and stored according to hazardous waste regulations until collection by authorized disposal services.

1,1,2-trichloroethane is classified under ADR Class 6.1 (toxic substances), Packing Group III for transportation purposes. It must be packaged in approved containers with proper hazard labels and documentation. Transport vehicles require appropriate placarding and drivers must have hazardous materials training. Shipping documentation must include proper shipping names, UN numbers, and emergency response information according to ADR regulations.

1,1,2-trichloroethane is subject to extensive European regulations including REACH registration requirements and CLP classification as Carc. 2 with acute toxicity warnings. The substance requires safety data sheets, proper labeling with GHS07 and GHS08 pictograms, and compliance with occupational exposure limits. Its use may be restricted in certain applications due to its carcinogenic classification and environmental concerns.
