It’s… Perchloroethylene is a non-flammable, colorless, volatile organic compound frequently used in dry cleaning applications. Other names for PCE include PERC, perchlor and tetrachloroethene. Although production of the chemical is decreasing, its persistence in the environment makes it a significant groundwater and air pollutant. It is a large percentage of all dry cleaning fluid used. Perchloroethylene is a chemical which is manufactured to be used in a wide range of commodities including stain removal, adhesives, metal degreasing products and the manufacturing industry. While TCE is used mainly as a pretreatment spot removing chemical in small volumes, PCE is used as a primary solvent in which textiles are completely immersed during drycleaning. ... perchloroethylene (redirected from Perchlorethylene) Also found in: … It is valued for its solvent capacity for clothing in the dry cleaning industry, for oil, grease and buffing compounds on metal parts and for baked-on carbon, dirt and oil on automotive parts and brakes. Often, these operations simply substitute other toxic ingredients for perc” [3]. Textile mills, vapour degreasers and metal cleaning operations, and rubber coatings also use tetrachloroethylene. It has also been in paints, spot removers, printing inks, household cleaners and glues. In the 1970’s and 80’s, in particular, industries that used chemicals for cleaning and degreasing didn’t realize that those chemicals could result in soil and groundwater contamination when spilled. Some examples of workers at risk of being exposed to tetrachloroethylene include the following: Workers in dry cleaning industries; Workers who use … Perchloroethylene (PERC) Perchloroethylene (PERC) is a man-made, non-flammable, colorless chemical that easily evaporates into the air. Perchlorethylene, Perchloroethylene, Perk, Tetrachlorethylene Colorless liquid with a mild, chloroform-like odor. Other release to the environment of this substance is likely to occur from: indoor use (e.g. A perc test is only necessary if a property doesn’t have access to a municipal sewer system . Tetrachloroethylene is used as a dry cleaning agent and metal degreasing solvent. Perchloroethylene (aka perc) Perchloroethylene, a chlorinated solvent, is the most common dry cleaning solvent in use today. The compounds in this class include compounds used in chlorinated degreasing and dry-cleaning such as perchloroethylene (PCE) and trichloroethylene (TCE), polychlorinated biphenyls (PCBs), and other halogenated industrial chemicals. Tetrachloroethylene (Perchloroethylene) 127-18-4 Hazard Summary Tetrachloroethylene is widely used for dry-cleaning fabrics and metal degreasing operations. Metal degreasers (for auto parts and electric motors) Perchloroethylene is a commonly used solvent (a substance, usually a liquid, capable of dissolving another substance). Not all drycleaners use Perc as their primary solvent, but many at least still use TCE for spot removal. Abbr. Instead, use toxic chemical free “wet cleaners” that use special non-toxic ingredients along with water or CO2 cleaners that use high-pressure carbon dioxide to launder clothes. Those in the fabric care industry commonly refer to PCE as Perc. PCE A colorless, nonflammable chlorocarbon, C2Cl4, used in dry-cleaning solutions and as an industrial solvent. used to protect surfaces from chemical etchings in the aerospace and other industries.

Perc, one of the first 10 chemicals, is a chemical used in dry cleaning, degreasers, paints, and a range of other products. What is PERC? Specifically, it is a widely used solvent, especially in dry cleaning activities. PERC, also known as tetrachloroethene, or perchloroethylene (“perc” or “PERC”), is a colorless liquid typically used as a cleaning solution by dry cleaners.While it’s a great cleaning agent, its numerous health side effects make PERC a horrible choice for use in dry cleaning. Tetrachloroethylene is used in many industries. Perchloroethylene (PCE) is a chemical that has been used as a degreaser and as a dry cleaning agent. machine wash liquids/detergents, automotive care products, paints and coating or adhesives, fragrances and air fresheners), outdoor use as processing aid and indoor use in close systems with minimal release (e.g. PCE is used primarily for metal degreasing and … If a worker is exposed to 211 mg/m 3 of perc over 2 hours and 305 mg/m 3 for 3 hours what is the maximum allowable concentration they can be exposed to for 3 hours and be at half the PEL? Perchloroethylene is a man-made substance and is an extremely effective non-flammable solvent used in industrial dry-cleaning. It can be added to solvent soaps, printing inks, It’s used to dry clean fabrics, manufacture other chemicals, and degreasing metal parts. Perchloroethylene (perchlor) is a chlorinated solvent that is used extensively by dry cleaning plants. For personal protection see section 8. Perchloroethylene is a colorless liquid used primarily in industrial settings for the production of fluorinated compounds and as a solvent. A perc test, which paves the way for a septic system on your property, is only necessary when the property does not already have access to a municipal sewer system. 2. By the 1930s cleaners began using perchloroethylene, commonly called "perc," a chlorinated solvent. Most people can smell tetrachloroethylene when it is present in the air at a level of 1 part in 1 million parts of air (1 ppm) or more. Perchloroethylene (perc) is a common solvent used in dry-cleaning. However, as a volatile organic solvent, perc may pose serious health hazards if exposure is not properly controlled. In PCE is a colorless, nonflammable liquid with a faint, sweet odor. Tetrachloroethylene, also called perchloroethylene, a colourless, dense, nonflammable, highly stable liquid belonging to the family of organic halogen compounds.Tetrachloroethylene is a powerful solvent for many organic substances. Reacts violently with finely dispersed light metals (aluminum) and zinc. PCE is used as a solvent on a wide array of organic soils and contaminants. You may also hear a perc test described as a “deep hole test.” People may talk about a lot “perking” when it passes the test. Uses of Perchloroethylene This chemical is also used as a solvent for cleaning and degreasing, and in lubricants, adhesives, and sealants. It is primarily used to produce fluorinated compounds, such as hydrofluorocarbons (HFCs) and hydrochlorofluorocarbons (HCFCs) followed by dry cleaning and vapor degreasing solvents. PERC is often used in dry cleaning, but is also used in manufacturing and in auto repair shops. Other names for tetrachloroethylene include perchloroethylene, PCE, perc, tetrachloroethene, and perchlor. [Handling Chemicals Safely 1980 p. 887].
