What defines the Type IV dry cleaning systems?

Type IV dry cleaning systems are characterized specifically by their use of nonflammable liquid solvents. This classification is important in the context of safety and regulatory compliance. Nonflammable solvents provide a significant advantage in reducing fire hazards within dry cleaning operations. By utilizing these types of solvents, the risk of ignition and subsequent fire is minimized, resulting in safer working conditions for operators and customers alike.

The use of nonflammable solvents also aligns with various safety codes and regulations that mandate certain practices in commercial and industrial applications. This specific focus ensures that Type IV systems are designed to operate safely without the additional risks associated with flammable or combustible solvents.

Understanding this distinction is essential for those involved in the mechanical codes and standards governing dry cleaning processes, as it directly influences not only operational safety but also the required compliance measures for such systems.
