What is the flash point of #6 Fuel oil?

The flash point of #6 fuel oil is a critical characteristic that helps determine its handling and storage safety. The correct answer, 140 degrees F, is the typical flash point for this type of fuel oil.

Flash point refers to the lowest temperature at which vapors from a fuel can ignite when exposed to an open flame or spark. The relatively high flash point of #6 fuel oil indicates that it is less volatile compared to lighter oils, which require lower temperatures to vaporize and ignite. This trait is important in ensuring safe storage and use, as it helps prevent accidental ignition during handling.

In contrast, the other temperatures provided are either too low for #6 fuel oil or apply to more volatile fuels, which burn more readily at lower temperatures. Understanding flash points is essential in HVAC and fuel management, ensuring that appropriate measures are taken when working with various fuels to protect both personnel and property.
