What type of dry cleaning system uses flammable liquid solvents with a flash point at or above 100ºF and below 140ºF?

The correct answer is Type II Dry Cleaning Systems because they are specifically designed to use flammable liquid solvents that have a flash point at or above 100ºF and below 140ºF. This classification accommodates processes that rely on solvents in a controlled manner while maintaining safety protocols to mitigate risks associated with flammability.

Type II systems are distinguished from Type I systems, which use non-flammable solvents, and Type III and Type IV systems, which employ flammable solvents with flash points below 100ºF and have different operational and safety requirements. The focus on the flash point range in Type II ensures that these systems operate under more rigorous safety measures than lower flash point systems, aligning with established safety guidelines within the North Carolina Mechanical Code. This ensures that the equipment and facilities using Type II systems adhere to regulations that prioritize the safety of operations involving flammable materials.
