Today the shelving was being tempermental so I was asked to check on it. The whole system was acting strange blinking red, two blinking red and yelloew, and two blanked arrows. While I was putting in the safety override in aisle 61A the part that held the override broke and went into the machinery I did not put any excess force on it. I had Caleb and Erika who was with me to write down what happened and I will leave that on Pat's desk. A repair man will probably have to be caled to fix that part afterwards the shelving started working again.
