Machine Safety on GRAM Cryos

Abstract

The purpose of this project was the improvement of two GRAM Cryo tumblers which are new equipment that required complete installation qualification (IQ) validations, prior to delivering them to the manufacturing and process areas. These tumblers needed machine safety improvements to comply with the observations indicated in an audit conducted in 2018. All the observations stated on the audit were analyzed and actions were determined to comply with each item pointed out. A validation plan (VP) was created prior to the technical improvements performed by the technical contractor. Wiring labeling, addition of safety relay, emergency stop, reset button, indicator lights and new sensor in compliance with Performance Level d (PLd) were installed in the equipment. IQ protocol was updated and executed with no issues. Key Terms ⎯ Installation Qualification (IQ), Machine Safety Improvements, Performance Level d (PLd), Wiring Labeling.
