This category addresses the design and lifecycle control of compressed air and process gas systems in GMP manufacturing. It covers risk-based qualification, performance monitoring, and requalification of compressed air, cylinder-supplied gases, and on-site nitrogen generation to ensure continued fitness for intended use.
1. Purpose and Scope This article defines a structured approach for the qualification, ongoing monitoring, and requalification of gas utilities used in GMP manufacturing, including compressed air systems, process gas systems, and on-site nitrogen generation. Gas utilities are considered GMP-relevant utilities when their failure, contamination, or loss of control could reasonably affect product quality, equipment…
1. Role of Process Gas Systems in GMP Manufacturing Process gas systems provide gases used to support manufacturing operations, equipment function, and, in some cases, direct interaction with product or product-contact environments. Common process gases in GMP facilities include nitrogen, carbon dioxide, oxygen, and specialty gases supplied via cylinders or bulk sources. From a regulatory…
1. Role of Compressed Air in GMP Manufacturing Compressed air is one of the most widely used utilities in GMP-regulated facilities and one of the most frequently underestimated. It is routinely used to operate equipment, control valves, actuate instruments, and support manufacturing operations. In many facilities, compressed air also comes into indirect or direct contact…
