Will mineral spirits effectively take away stains? Investigators wished to find out which of the earlier engineering control suggestions had been still valid, along with providing drycleaners with present suggestions for sensible control measures.

The most typical petroleum-based mostly dry cleaning solvents in the U.S. All petroleum-primarily based, dry cleaning solvents are aliphatic hydrocarbons having a carbon chain of eight to twelve carbons. Because of this, distillation is very important, as well as antibacterial additives in the solvent.27 Petroleum solvents are toxic, but they're typically thought to be less toxic than PERC. The NIOSH really helpful exposure limit for mineral spirits is 350 mg/m3 or approximately 66 ppm.

Mineral spirits is a category II, combustible liquid with a flash point of 49°C (120°F). Its decrease explosive restrict is 0.7% or 7,000 ppm. Stoddard Solvent/mineral spirits. All of these solvents are flammable or combustible liquids. Petroleum-based solvents have a a lot decrease Kauri-Butanol (KB) worth than PERC. 14. Are only authorised containers used for storing flammable or combustible liquids?
