Heating volatile liquids open flame
WebThe National Fire Protection Association (NFPA) defines a flammable liquid as a liquid with a flash point that does not exceed 100°F (38°C). Combustible liquids have flash points at or above 100°F (39°C). Flammable and combustible liquids exhibit multiple health hazards besides the risk of fire. Example are listed in the table below.
