## Narrative

Employees in the Service Shaft were cutting out an old 6"" diameter air line when a piece of hot slag started a small methane fire in the shaft approximately at the 689.5 level.  Methane was coming out of a joint in the concrete in the shaft.  When the employees discovered the fire, they went to the level of the ignition and extinguished the fire with a fire extinguisher.
