What should the flash point of Class I combustible liquids be?

Class I combustible liquids are characterized by having a flash point that is at or below 100°F (37.8°C). This classification is crucial for understanding the flammability and safety precautions that need to be taken when handling and storing these liquids. The flash point is the lowest temperature at which vapors from a liquid can ignite in air, meaning that liquids in this class pose a higher risk of ignition and fire potential in various environments.

When liquids have flash points at or below this temperature, they require stricter safety measures and are often subject to specific regulations to prevent hazards. This standard is an important aspect of fire safety and hazardous materials management, ensuring that individuals working with these substances are aware of the risks involved and can take proper precautions.

The other options do not accurately reflect the criteria for Class I combustible liquids. Knowing the specific flash point range is critical for safety professionals in assessing risks and compliance with safety standards in the workplace.
