There was a plug in the #1 separator chute. EE turned on air lance, picked it up, & just before EE went to put it in the trap door to work out the chunks, EE felt a zap go through palms & gripped the bar tighter. Another EE pulled the bar out of EE's hands. The area was tested for static issues and none found. Dr found no abnormalities. EE took pain meds so missed one day.
