The textile industry uses perc as a spotting agent for the removal of spinning oils and lubricants. The U.S. National Toxicology Program has classified it as a "probable" human carcinogen. 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? For personal protection see section 8. Chlorinated solvents are also used as a source of chloride for reforming catalysts. What Is a Perc Test? Perchloroethylene (perc) is a common solvent used in dry-cleaning. Specifically, it is a widely used solvent, especially in dry cleaning activities. It is primarily used to produce fluorinated compounds, such as hydrofluorocarbons (HFCs) and hydrochlorofluorocarbons (HCFCs) followed by dry cleaning and vapor degreasing solvents. Perchloroethylene (“perc”) has long been recognized as an effective dry cleaning solvent and today it is by far the most commonly used solvent in dry cleaning shops. Smoking, eating and drinking should be prohibited in the application area. Tetrachloroethylene is used as a dry cleaning agent and metal degreasing 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 is a man-made substance and is an extremely effective non-flammable solvent used in industrial dry-cleaning. Used by approximately 70% of the 26,000 cleaners in the USA, perc (brand name: Dowper from Dow Chemical and PerSec from Occidental … Those in the fabric care industry commonly refer to PCE as Perc. It has also been in paints, spot removers, printing inks, household cleaners and glues. Abbr. Textile mills, vapour degreasers and metal cleaning operations, and rubber coatings also use tetrachloroethylene. Not all drycleaners use Perc as their primary solvent, but many at least still use TCE for spot removal. Tetrachloroethylene (Use in Dry Cleaning and Reporting Requirements) Regulations (SOR/2003-79) Solvent degreasing regulations ; Publications. Perchloroethylene (PERC) Perchloroethylene (PERC) is a man-made, non-flammable, colorless chemical that easily evaporates into the air. See more.
