Although most laboratory staff know that it is not safe to heat flammable liquids over an open flame there would appear to be a mistaken belief that an electric hot-plate is a satisfactory alternative.
It is recommended that the heating of highly flammable liquids should be carried out in such a way as to ensure that:-
Neither of these arrangements precludes the proper heating of reaction mixtures or carrying out distillations using properly installed electric mantles provided that there is adequate condensation or removal of any ignitable vapour.
Commonly used highly flammable liquids with flash points below 30°C:-
Acetone Hexane Benzene Methanol Butanol Methyl ethyl ketone Carbon disulphide* Pentane Cyclohexane Petroleum ether* Cyclohexene Propanol Dioxane Propyl ether Ethanol Pyridine Ethyl acetate Toluene Ethyl ether* Xylene
*Have ignition temperatures below 200°C
