What is the flash point of a combustible liquid?

• A. At or above 0°F
• B. At or below 100°F
• C. At or above 100°F and below 200°F
• D. At or above 200°F

Answer: (C)

The flash point of a combustible liquid is defined as the minimum temperature at which enough vapor is produced to ignite when exposed to an ignition source. Specifically, combustible liquids are classified based on their flash points, which helps in assessing the associated fire hazards. The correct choice identifies that the flash point of a combustible liquid is at or above 100°F and below 200°F. This classification is crucial for safety in handling and storage, as it indicates a higher risk for ignition compared to non-combustible substances, which have flash points above 200°F. Understanding this range helps aviation personnel recognize materials that require careful management to prevent fire hazards. In contrast, the other options either misclassify the flash point of combustible liquids or refer to temperatures that are associated with different categories of liquids. Choices that suggest flash points at or below 100°F describe flammable liquids, which pose an even higher risk, while those suggesting temperatures above 200°F pertain to substances that are non-combustible, significantly reducing fire risks. Recognizing these distinctions is vital for maintaining safety protocols in aviation environments.
