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 ...
Tetrachloroethylene, also known as perchloroethylene [a] or under the systematic name tetrachloroethene, and abbreviations such as perc (or PERC), and PCE, is a chlorocarbon with the formula Cl 2 C=CCl 2. It is a non-flammable, stable, colorless and heavy liquid widely used for dry cleaning of fabrics.
This superfund site consists of two dangerous chemical compounds, trichloroethylene (TCE) and perchloroethylene (PCE). Both consist of very harmful toxins that have long term effects on the central nervous system. PCE is generally used for dry cleaning fabrics and decreasing metals, while TCE is typically used as an industrial solvent. [2]
It is dangerous from both inhalation and dermal exposure and was most strongly associated with immunosuppressive effects for acute exposure, as well as autoimmune effects for chronic exposures. [50] Chronic exposure to trichloroethylene has also been linked to an increased risk of Parkinson's Disease.
The density of perchloroethylene is around 1.62 g/cm 3 at room temperature (62% heavier than water), and the sheer weight of absorbed solvent may cause the textile to fail under typical forces during the spin extraction cycle, unless the mesh bag provides mechanical support. Not all stains can be removed by dry cleaning. Some need to be treated ...
This is the list of extremely hazardous substances defined in Section 302 of the U.S. Emergency Planning and Community Right-to-Know Act (42 U.S.C. § 11002).The list can be found as an appendix to 40 CFR 355. [1]
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 handling of this chemical may incur notable safety precautions. It is highly recommended that you seek the Material Safety Datasheet for this chemical from a reliable source such as SIRI, and follow its directions.
