What is the flash point benchmark for Class IIIB liquids?

The flash point benchmark for Class IIIB liquids is established at 200°F. Class IIIB liquids are defined as those that have a flash point at or above 140°F but below 200°F. Therefore, 200°F serves as a critical threshold that differentiates Class IIIB liquids from those in other classifications.

Understanding flash points is essential in HVAC and refrigeration practices, particularly in safety and regulatory compliance. Liquids with flash points of 200°F or higher are considered less volatile and pose a lower risk in terms of flammability, which is why this specific temperature is significant in categorizations of liquids. This is particularly important for contractors and technicians who handle, store, or work with these types of materials, ensuring that they are aware of safety protocols associated with different classes of flammable liquids.
