## Narrative

EE was unhooking the engine from the rail cars.  He could not reach the air valve on the engine from the side he was on so he crawled up on the railcar hitch so he could get to the valve.  When he did, he slipped.  He used his right arm to catch himself.  That is when he hurt his wrist.
