ASME has been defining piping safety since 1922. ASME B31Q establishes the requirements for developing and implementing an effective Pipeline Personnel Qualification Program. It specifies the requirements for identifying covered tasks that impact the safety or integrity of pipelines, for qualifying individuals to perform those tasks, and for managing the qualifications of pipeline personnel. ASME B31Q establishes the requirements for developing and implementing an effective Pipeline Personnel Qualification Program utilizing a combination of technically based data, accepted industry practices, and consensus-based decisions. This standard also offers guidance and examples of a variety of methods that may be used to meet selected requirements. ASME B31Q specifies the requirements for identifying covered tasks that impact the safety or integrity of pipelines, for qualifying individuals to perform those tasks, and for managing the qualifications of pipeline personnel. With the exceptions of tasks that are primarily intended to ensure personnel safety or design or engineering tasks this standard applies to tasks that impact the safety or integrity of pipelines Careful application of these B31 codes will help users to comply with applicable regulations within their jurisdictions, while achieving the operational, cost and safety benefits to be gained from the many industry best-practices detailed within these volumes. Intended for liquid and gas pipeline industries, contractors, service providers, and federal and state regulators.
