Liquids with flashpoint at or above 73 °F (22.8 °C) and below 100 °F (37.8 °C) are classified as:

Liquids with flashpoint at or above 73 °F (22.8 °C) and below 100 °F (37.8 °C) are classified as:

• A. Class IC
• B. Class IB
• C. Class IA
• D. Class II

Answer: (A)

Liquids are categorized by how easily they can form ignitable vapors, using the flashpoint as the key measure. The flashpoint is the lowest temperature at which a liquid can emit enough vapor to ignite in the presence of an ignition source. When the flashpoint falls between 73 °F and 100 °F (roughly 22.8 °C to 37.8 °C), the liquid is classified as Class IC. This classification sits in the middle of the flammable-liquid subcategories: liquids with flashpoints below 73 °F are in the more hazardous subclasses (IA or IB, depending on the boiling point), while liquids with flashpoints at or above 100 °F are considered combustible (Class II or higher). So, the given temperature range corresponds to Class IC.
