What class of liquid has a flash point below 140°F?

  1. Class I

  2. Class II

  3. Class III

  4. Class IV

The correct answer is: Class II

The correct classification for a liquid with a flash point below 140°F is Class I. This class is defined by having a flash point below this temperature, which indicates that these liquids can easily ignite and pose significant fire hazards. Understanding flash points is crucial in safety management within healthcare environments, as they can influence how substances are stored, handled, and disposed of, thereby affecting overall safety protocols. Class I liquids include those that are highly flammable, necessitating special precautions during their use. For clarification, Class II liquids have flash points at or above 140°F and not exceeding 200°F, which means they are less volatile compared to Class I. Class III liquids are further divided into Class IIIA and Class IIIB, with flash points above 200°F. Class IV is composed of liquid substances that are considered combustible but have even higher flash points. This categorization is essential in establishing safety guidelines and handling procedures to mitigate risks associated with fire hazards in healthcare settings.
