Flammable and combustible organic solvents are amongst the most dangerous chemicals in the lab. A measure of how ignitable a particular solvent is the flashpoint ; defined as the lowest temperature at which a material can form an ignitable mixture with air and produce a flame when a source of ignition is present. | Flammable and combustible organic solvents are amongst the most dangerous chemicals in the lab.
