Trichloroethylene (TCE) is a halocarbon with the formula C 2 HCl 3, commonly used as an industrial metal degreasing solvent. It is a clear, colourless, non-flammable, volatile liquid with a chloroform-like pleasant mild smell [3] and sweet taste. [9] Its IUPAC name is trichloroethene. Trichloroethylene has been sold under a variety of trade names.
Many gases have toxic properties, which are often assessed using the LC 50 (median lethal concentration) measure. In the United States, many of these gases have been assigned an NFPA 704 health rating of 4 (may be fatal) or 3 (may cause serious or permanent injury), and/or exposure limits (TLV, TWA/PEL, STEL, or REL) determined by the ACGIH professional association.
The chemicals — trichloroethylene and perchloroethylene (PCE or perc) — can cause multiple kinds of cancers and damage to the kidney, liver and immune and nervous systems at high exposure ...
There are three levels of PAC value (1 to 3) where each successive value is associated with an increasingly severe effect from a higher level of exposure. Each level is defined as follows: PAC-1 : Mild, transient health effects. PAC-2 : Irreversible or other serious health effects that could impair the ability to take protective action.
Acute Exposure Guideline Levels (AEGLs) set levels of chemical concentration that pose a defined level of risk to humans (the general population, including susceptible individuals). [ 1 ] [ 2 ] [ 3 ] These levels are used in preventing and responding to disasters .
The Hierarchy of Occupational Exposure Limits, of which occupational exposure banding is a member. Occupational exposure banding, also known as hazard banding, is a process intended to quickly and accurately assign chemicals into specific categories (bands), each corresponding to a range of exposure concentrations designed to protect worker health.
This included levels of TCE which were over 300 times the federal drinking water standard. The various concerns who owned the View-Master franchise in the 1950s through the 1970s (Sawyer's and GAF), acknowledged using TCE to clean and de-grease parts and equipment, and disposed of the chemical on-site. [1] This disposal was legal at the time.
