At what temperature is the flashpoint of a substance typically recorded?

The flashpoint of a substance is defined as the lowest temperature at which its vapors can ignite in air. For many combustible liquids, especially those commonly dealt with in heating applications, the flashpoint is often around 100°F. This temperature is significant because it indicates when a liquid might pose a fire hazard if enough heat is present for ignition to occur. Knowing the flashpoint is crucial for safely handling and storing these substances, as it helps technicians assess the risk of fire and implement necessary safety measures.

While different substances have varying flashpoints, 100°F is a commonly used benchmark for many oil-based products in the heating industry, making it a critical point of reference for technicians working with oil heat systems. Other temperatures listed pertain to other combustible materials or differ based on the specific chemical properties of the substances involved, emphasizing the importance of understanding the typical classifications for oil heat applications.
