Health and Safety Concerns
TCE is recognized as a potential health hazard. It is classified as a suspected human carcinogen by the International Agency for Research on Cancer (IARC) and has been linked to kidney cancer and other health issues. Exposure can occur through inhalation, skin contact, or ingestion, leading to symptoms such as headaches, dizziness, and respiratory irritation. Long-term exposure may affect the nervous system and other organs.
Regulatory Status
Due to its health risks, the use of trichloroethylene has been phased down in many applications, and regulatory bodies have established guidelines for its safe handling and exposure limits in occupational settings.
In summary, trichloroethylene (CAS 79-01-6) is a versatile solvent with significant industrial applications but poses serious health risks that necessitate careful management and regulation.
