As a subject matter expert in the field of chemical safety and hazard identification, I have extensive experience in dealing with various types of fuels and their properties. One of the critical parameters that we consider when assessing the safety of a fuel is its flash point. The flash point is the lowest temperature at which a substance can vaporize to form an ignitable mixture in air under specific test conditions. It is a crucial factor in determining the fire and explosion hazards of a substance.
Liquefied Petroleum Gas (LPG) is a versatile fuel that is widely used in residential, commercial, and industrial applications. It is typically a mixture of hydrocarbons, primarily propane (C3H8) and butane (C4H10), and sometimes includes small amounts of other hydrocarbons. The flash point of LPG is a significant concern for safety reasons, especially in environments where the gas might be stored or used.
The reference content provided states that the flash point of LPG (propane) is -104°C or -156°F. This indicates that at temperatures above this threshold, propane can form a flammable mixture with air that can ignite if an ignition source is present. It's important to note that the flash point is a specific condition that is measured under controlled laboratory conditions and may not always reflect real-world scenarios where various factors can influence the behavior of the gas.
However, it is essential to verify this information with more reliable sources to ensure accuracy. The flash point can vary depending on the specific composition of the LPG, as different hydrocarbons have different flash points. For instance, the flash point of pure propane is indeed very low, but the presence of butane or other components can raise the flash point slightly.
To provide a comprehensive answer, let's delve into the nuances of LPG's flash point:
1. Compositional Variation: LPG can have varying compositions, which can affect its flash point. Propane has a lower flash point than butane, so a higher concentration of propane will generally result in a lower flash point for the LPG mixture.
2. Testing Conditions: The flash point is determined using specific test methods, such as the Tagliabue Open Cup (TOC) or the Pensky-Martens Closed Cup (PMCC). The results can differ slightly based on the method used.
3. Safety Implications: A lower flash point means that the fuel can ignite more easily, which is a significant safety concern. It is why proper storage, handling, and ventilation are critical when dealing with LPG.
4. Regulatory Standards: Different countries and jurisdictions may have specific regulations regarding the flash point of fuels, which can affect the transportation, storage, and use of LPG.
5. Continuous Ignition Source: As mentioned in the reference content, if a continuous ignition source is present, LPG can burn even below its stated flash point. This highlights the importance of eliminating potential ignition sources in areas where LPG is used.
6. Storage and Handling: Understanding the flash point of LPG is crucial for safe storage and handling practices. It helps in determining the appropriate equipment and safety measures needed to prevent accidental ignition.
7.
Emergency Response: Knowledge of the flash point is also vital for emergency responders. It helps them to assess the risks and take appropriate action in the event of a fire or potential fire involving LPG.
In conclusion, while the reference content provides a general idea of the flash point of LPG, it is crucial to consult reliable and up-to-date sources or industry standards to obtain the most accurate information. The flash point is a critical parameter for assessing the fire and explosion hazards of LPG and plays a significant role in ensuring the safe use and handling of this fuel.

The flash point of LPG (propane) is -104--C or -156--F. This is the minimum temperature at which propane will burn on its own after having been ignited. Below this temperature, it will stop burning on its own. However, if a source of continuous ignition is present, it will burn below -104--C.
