What is the flash point of LP-Gas?

The flash point of LP-gas, specifically propane, is approximately -156°F (-104.4°C). The flash point is the lowest temperature at which vapor from a volatile substance can ignite when exposed to an open flame or spark. Propane has a very low flash point, which means it can easily produce flammable vapors at relatively low temperatures, making it important to handle with care, especially during storage and dispensing.

Understanding the properties of LP-gas is crucial for ensuring safety during its use. The other options reflect various temperatures, but only the first option aligns with the well-documented flash point of propane. For instance, the option citing a flash point of 0°F (-18°C) significantly underestimates the volatile nature of propane, while the other choices provide even higher temperatures, which are inconsistent with propane's characteristics. Knowing the correct flash point helps in assessing the risks associated with LP-gas and implementing appropriate safety measures during handling and storage.
