What is the flash point of propane?

The flash point of propane is approximately -104°F (-76°C). This is the temperature at which propane can form a flammable mixture with air. Knowing the flash point is crucial for safety and handling procedures in the LP-Gas industry, as it indicates the conditions under which propane could ignite in the presence of an ignition source.

A flash point that is very low, as seen with propane, means that at relatively low temperatures, this gas can easily catch fire when mixed with air, which is a significant consideration when storing or transporting propane. The low flash point demonstrates the importance of taking proper precautions during handling and usage.

The other temperature points provided do not correctly represent the flash point of propane. For example, 32°F (0°C) is above freezing and would not be suitable for propane, while 212°F (100°C) is the boiling point of water and is much too high for propane. Lastly, 0°F (-18°C) is also not low enough to represent the true flash point of propane, making -104°F (-76°C) the accurate choice for safety and operational standards in propane handling.
