An employee was clearing a jam from the blow mold machine because bottles were stuck between the blow mold machine and the cooling bed. The employee stopped the cooling bed and used a resin rod that was approximately 24 inches long to knock the bottles down to the floor. As they reached for the bottles, the swing arms that grab the bottles from the blow mold machine and lay them on the cooling bed activated and struck the employee. The employee sustained a severe laceration to their left forearm.
