What is the flashpoint of propane?

The flashpoint of propane is -156°F. This temperature indicates the lowest point at which propane can vaporize to form an ignitable mixture in air. Understanding the flashpoint is crucial for safety and handling procedures in environments where propane is used or stored.

Propane is a highly flammable gas at room temperature and pressure, and its low flashpoint means that it can easily ignite from an open flame or spark. This characteristic makes it essential for technicians and professionals in the propane industry to take proper precautions when working with this fuel.

In contrast, the other temperatures presented do not represent the characteristics of propane accurately. For instance, temperatures like -50°F and 32°F do not reflect the correct ignition potential of propane, while 140°F is significantly above its flashpoint, indicating that propane would not ignite at such a high temperature. Understanding the correct flashpoint helps in assessing risks and implementing safety measures in propane applications.
