What is the ignition temperature of propane, along with its flammable range?

Propane has an ignition temperature of approximately 896°F (or around 480°C). This is the temperature at which propane will ignite in the presence of a heat source. The flammable range of propane, which is the concentration range in air where it can ignite and burn, is between 2.1% and 9.5%. This means that propane can form a flammable mixture with air within this specific percentage range. When the concentration of propane in air falls below 2.1% or exceeds 9.5%, it is no longer considered flammable.

Understanding the ignition temperature and the flammable range of propane is crucial for fire fighters when assessing potential fire hazards. This knowledge allows them to make informed decisions about safety measures and firefighting tactics in scenarios involving propane. For instance, knowing that propane can ignite at 896°F ensures that firefighters take appropriate precautions when working around sources of heat that could reach or exceed this temperature. Additionally, awareness of the flammable range helps in evaluating the risk of ignition when propane is present in an environment.
