Corrected entry: The bad guy soaks the woman with fuel. The bad guy then shoots Denzel, and runs outside. He then fires at a propane tank that causes the entire building to explode. The fireball is enormous, and flaming debris is everywhere, including being inches from the woman. But she never ignites. (01:31:00 - 01:33:05)

Correction: He soaks her with diesel fuel. It is very difficult to ignite diesel unless it is very hot or atomized into a spray. You could throw a box of lit matches into a can of diesel and they would likely all go out without igniting the fuel.
With temperatures of 3,850°, I'm sure that'd be plenty hot enough. 10 ft from the explosion, you're probably talking 1,800°, plenty sufficient to ignite the diesel. Not to mention that concussive force from all those tanks exploding probably would have killed Denzel and the woman.
