From The American Heritage® Dictionary of the English Language, Fourth Edition:
Usage Note: Historically, flammable and inflammable mean the same thing. However, the presence of the prefix in- has misled many people into assuming that inflammable means “not flammable” or “noncombustible.” The prefix in- in inflammable is not, however, the Latin negative prefix in-, which is related to the English un- and appears in such words as indecent and inglorious.

But many people are not aware of this derivation, and for clarity’s sake it is advisable to use only flammable to give warnings.
