## Narrative

A mobile jib crane was being used to lift a piece of grating.  When the grating did not move the crane was readjusted while still attached and under pressure.  The grating cross bar failed and caused the chain assembly and crane arm to strike the EE in the face.  EE was treated by MD and taken off work.
