199.4 °F
Flammable liquid is any liquid having a flashpoint at or below 199.4 °F (93 °C).
What is a Class 1 liquid?
Class I liquids are the most hazardous from a fire safety standpoint, while Class IIIB liquids are the least hazardous. Class IA liquids are liquids that have flash points below 73 °F (22.8 °C) and boiling points below 100 °F (37.8 °C). Additionally, unstable flammable liquids are treated as Class IA liquids.
What is considered a low flash point?
Flammable liquids have a flash point of less than 100°F. Liquids with lower flash points ignite easier. Combustible liquids have a flashpoint at or above 100°F.
What class makes reference to flash point and boiling point?
Class IB Flammable Liquids A Class IB flammable liquid is any liquid with a closed-cup flash point below 73°F (23°C) AND with a boiling point at or above 100°F (38°C).
How is flash point calculated?
Flash points are determined experimentally by heating the liquid in a container and then introducing a small flame just above the liquid surface. The temperature at which there is a flash/ignition is recorded as the flash point. Two general methods are called closed-cup and open-cup.
Which has highest flash point?
Examples
| Fuel | Flashpoint | Autoignition temperature |
|---|---|---|
| Jet fuel (A/A-1) | >38 °C (100 °F) | 210 °C (410 °F) |
| Kerosene | >38–72 °C (100–162 °F) | 220 °C (428 °F) |
| Vegetable oil (canola) | 327 °C (621 °F) | 424 °C (795 °F) |
| Biodiesel | >130 °C (266 °F) |
What is meant by flash point?
Flash point, the lowest temperature at which a liquid (usually a petroleum product) will form a vapour in the air near its surface that will “flash,” or briefly ignite, on exposure to an open flame. The flash point is a general indication of the flammability or combustibility of a liquid.

Which will catch fire easily?
Flammable and combustible liquids Besides gasoline and lighter fluid, things like rubbing alcohol, nail polish remover, hand sanitizer and wart remover can easily catch fire.
What is the flash point of water?
For example, pure ethanol will flash at 12.7°C; a 70% mixture by weight in water will flash at 23°C; and a 24% mixture in water at 60.5°C. Transportation temperature: materials with high flash points may be considered flammable if transported at temperatures above their flash points.
