## Narrative

3 men were replacing mounting bolts on a HP1000 crusher.  While installing a 2' I beam pusher, they attempted to strike an arc, instead they got a flash fire from the arc strike.  The bottom hydraulic hose under pressure must have had a pinhole leak putting out a vapor cloud.  No one saw any traces of the hydrualic leak before starting the job.
