The Hazards and Uses of 1,1,2-Trichloroethane

1,1,2-Trichloroethane (TCA) is a colorless, heavy liquid that is used as a solvent and as an intermediate in the production of various chemicals. TCA has a sweet odor and a boiling point of 115 °C. It is highly flammable and toxic, and therefore requires proper handling and storage.

Hazards of 1,1,2-Trichloroethane

1,1,2-Trichloroethane is a highly hazardous substance that can cause serious health problems when ingested, inhaled, or exposed to skin. It is classified as a Category 2 reproductive toxin, which means it has the potential to cause fertility problems and harm to unborn children.

Inhalation of TCA fumes can cause dizziness, headaches, nausea, vomiting, and difficulty breathing. Chronic exposure to TCA can lead to liver damage, kidney damage, and neurological problems. It can also cause skin irritation and chemical burns when in direct contact.

Ingestion of TCA can cause nausea, vomiting, abdominal pain, and liver damage. If ingested in large amounts, it can be fatal.

Due to the serious hazards associated with 1,1,2-Trichloroethane, it is crucial to handle and store it properly to prevent accidents and exposure.

Uses of 1,1,2-Trichloroethane

1,1,2-Trichloroethane has several industrial applications. It is used as a solvent for cleaning and degreasing metal parts, machinery, and electronic equipment. It is also used as a solvent for adhesives, coatings, and inks.

TCA is an important intermediate in the production of various chemicals, including vinylidene chloride, which is used to make plastics, and trichloroethylene, which is used as a solvent and as an intermediate in the production of refrigerants and other chemicals.

TCA is also used in the production of pesticides and herbicides, although its use in these products has been reduced due to its toxic nature.

Regulations on 1,1,2-Trichloroethane

1,1,2-Trichloroethane is regulated by several government agencies, including the Occupational Safety and Health Administration (OSHA) and the Environmental Protection Agency (EPA).

OSHA has set a permissible exposure limit (PEL) of 50 parts per million (ppm) for TCA in the workplace. Employers must ensure that their workers are not exposed to levels of TCA above the PEL.

The EPA has classified 1,1,2-Trichloroethane as a hazardous air pollutant under the Clean Air Act. Companies that produce or use TCA are required to report their emissions to the EPA and implement measures to reduce them.

In addition, TCA is listed on the Toxic Substances Control Act (TSCA) Chemical Substance Inventory. Companies that manufacture, import, or process TCA are required to comply with TSCA reporting and recordkeeping requirements.

Conclusion

1,1,2-Trichloroethane is a highly hazardous substance that is used in various industrial applications. It has serious health risks associated with it, including liver and kidney damage, neurological problems, and reproductive toxicity. Proper handling and storage of TCA is crucial to prevent accidents and exposure.
