EE had wet down the muck-pile, while rolling up water hose EE slipped on some residual hard-cap paste landing on EE's right arm. At the end of shift EE requested to be seen by the Pogo physician's assistant where it was determined to send EE to Fairbanks for an x-ray; which was definitive for a fracture. EE is onsite currently w/restrictions and a splint/cast.
