At what temperature is kerosene classified as fuel oil in terms of flash point?

Kerosene is classified as fuel oil based on its flash point, which is the temperature at which it produces enough vapor to ignite when exposed to an open flame. The correct classification indicates that kerosene has a flash point of 100°F. This temperature is significant for safety and handling purposes, as it helps determine the conditions under which kerosene can be safely stored and used.

Flash points below 100°F typically categorize substances as flammable liquids, necessitating more stringent safety regulations, while those above 100°F tend to fall under combustible liquids, which have fewer restrictions. Since kerosene has a flash point of 100°F, it is associated with specific handling and storage protocols to ensure safety in HVAC applications and related uses. This understanding is crucial for professionals working with fuels in order to manage risks associated with fire and combustion effectively.
