If you should stumble upon a warning or description about a block, liquid, material or item being "inflammable", please note that this word means the exact same as "flammable".

Since rather many people - even native English-speakers - continually mistake "inflammable" for "non-inflammable" it's a good idea to revise this phrasing if you find it.

Still please mind that using "inflammable" instead of "flammable" is in no way a "misspelling" nor a "mistake".
