Kane's pyro nearly burns the Undertaker's face.

During the July 11, 1998 War zone broadcast, the Undertaker took on Vader in a one-on-one match.

During the Undertaker's entrance as he walked up the ring steps and raised his arms, the pyro technician, when turning on the lights, must've accidentally set off the Kane's pyro as well. Fire shot out of the ring post inches away from Undertaker's face causing him to flinch and back up.

Moments later in the match, Kane came down to the ring to intimidate the Undertaker by lighting his pyro. As he did, only 3 of the ring post shot fire out. The ring post that nearly burned the Undertaker earlier did not go off .
