Looking for the name of a Movie

[Leon]

Its driving me crazy,i cant recall the name or lead actor, the plot is quite fuzzy too

What i can recall that its centered on a Emergency services type "hero" possibly in a incident underground (a tunnel maybe) and its Hot or a hot environment

[Ebon_Drake]

Could be the Sly Stallone "classic" Daylight (http://en.wikipedia.org/wiki/Daylight_(film))?

[Leon]

Yes, that fits the bill.
I was wildly off on what i thought it was initially but the fireball in a tunnel is what i was thinking of

Thank you
