What type of hazards does a flash point indicate?

A flash point is the lowest temperature at which a substance can vaporize to form an ignitable mixture in air. This measurement is crucial for understanding the flammable characteristics of liquids, indicating how easily a material can catch fire under specific conditions. When a substance has a low flash point, it suggests that the material poses a significant risk of ignition, making it a chemical hazard.

Chemical hazards pertain specifically to the properties of substances that can lead to chemical reactions, including combustion. Therefore, knowing the flash point helps in assessing fire risks and implementing necessary safety precautions in handling and storage.

While biological, physical, and environmental hazards encompass other risks—such as exposure to pathogens, non-flammable physical conditions, and impacts on nature—they do not directly relate to the combustion characteristics signified by a flash point.
