Shipping reliever for lunch accidentally shipped Hazmat part to ORD. Paperwork was in error; was busy trying to pick AOGs (Aircraft on ground) and hotshots; realized it was has a Hazmat part tried to stop it from being taken but driver had already taken part away. Picked part and was no Hazmat material sticker on it only an ESDS (Electrostatic Discharge Sensitive).I failed to open box to check part. Assumed part was non-hazardous due to no labeling; nothing flagged when the ship was done.More help during lunch and making sure outside of the box containing Hazmat part is properly marked.
Commercial Airline Stores Personnel reported accidentally shipping Hazmat item with incorrect documentation and no required Hazmat label.
