Why do you need fuel to start a fire?
Because fuel is a FLAMMABLE material.
Are fumes from bleach flammable?
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.
