Is bleach flammable?
No, bleach is not flammable. The Material Safety and Data Sheet for a common brand of bleach says it does not ignite when exposed to an open flame.
No. Chlorine gas (though deadly) is non-flammable. However, fumes from chlorine bleach are not chlorine gas. Chlorine gas is Cl2 and is deadly but does not exist in nature, it must be manufactured. Evaporating bleach (NaOCl) generally fumes off oxygen and leaves NaCl (salt). None of these elements are flammable.
