Which type of dry cleaning system uses solvents with a flash point below 100ºF?

The correct answer is the type of dry cleaning system that uses solvents with a flash point below 100ºF, which is classified as Type I Dry Cleaning Systems. This classification is specifically designed for using solvents that are considered flammable. The flash point is an important safety metric because it indicates the temperature at which a solvent can form flammable vapors. In a Type I system, the use of solvents with low flash points poses increased hazards, necessitating strict adherence to safety codes and regulations to manage risks associated with flammability during the dry cleaning process.

Understanding this classification helps ensure that proper safety measures and equipment are implemented to protect workers and the environment in commercial dry cleaning operations. Types II, III, IV, and V do not include solvents with such a low flash point, instead designating other solvent classifications that align with higher flash point thresholds or entirely different dry cleaning technologies.
