## Narrative

EE was guiding the rod eye of a hydraulic cylinder with his hand in order to place blocking under the cylinder body when the rod suddenly and unexpectedly extended pinching his thumb between the rod eye and the wood supporting the boom. This could have been avoided by following our policy of using pry bars for this activity and cycling the cylinder to flush out air locks.
