Pipeline Personnel Qualification (ASME B31Q-2021)

For developing a Pipeline Personnel Qualification Program, professionals turn to ASME B31Q-2021: Pipeline Personnel Qualification.

The Advantages of Pipelines for Hazardous Liquid Transport

Several options for transporting gas and other hazardous liquids are viable, but pipelines have long proven to be the safest means of travel for these chemicals. In fact, due to automotive accidents, pipelines are 70 times safer than trucks for performing this task, and they can even transport far more materials than their road-based alternative.

However, pipelines are prone to rupture, and proper guidance is necessary to prevent any pipeline accidents, as the leaking gas and volatile chemicals can be severely detrimental to the nearby people and surrounding environment. Among the different causes for such an event, investigations conducted between 1975-1986 revealed that human error was a common culprit.

The Development of ASME B31Q

To combat the issue of human error in pipeline accidents, the US Department of Transportation made efforts throughout the following decade to establish specific training requirements for the qualifications of pipeline workers.

The final rule was non-prescriptive, and it consisted of protocols meant to assist regulators in the evaluation of qualification programs. However, in the early 2000s, the pipeline industry approached ASME to construct a consensus code that could eliminate any outstanding issues on the subject, resulting in the ASME B31Q Project Team. This led to the initial publication of ASME B31Q.

Pipeline safety remains a major issue. Since 1986, pipeline accidents have killed over 500 people, injured more than 4,000, and cost almost $7 billion in property damage. And all this excludes the practically immeasurable damage that has been waged on the environment. Adherence to the B31Q standard can reduce the likelihood of these incidents by solving one of their key causes, and the new revision, ASME B31Q-2021: Pipeline Personnel Qualification, updates the document’s content to improve the training process.

About ASME B31Q-2021

Like many other standards that serve to provide an overarching training process for industrial practices, ASME B31Q-2021 covers the requirements for determining a qualification program and training process that should cover tasks based off the workers’ responsibilities and prior skill level, in addition to evaluating their progress and allowing for a refresher process. Utilizing a combination of technically based data, accepted industry practices, and consensus-based decisions, the Pipeline Personnel Qualification Program outlined in the standard helps impact the safety or integrity of pipelines. Furthermore, ASME B31Q-2021 qualifies individuals for performing those tasks, and it helps manage the qualifications of pipeline personnel.

Strengthened knowledge on the many aspects of pipeline safety can help workers keep pipelines safe for themselves, others, and the environment.

SME Covered Task Identification Process

ASME B31Q-2021 does cover content unique to the challenges that pipeline workers can face while securing the healthy functioning of the equipment. For example, the standard calls for two primary methods for determining the covered tasks throughout the training process. The first of these is the SME (Subject Matter Expert) Covered Task Identification Process. This method involves a highly knowledgeable individual or group identifying a list of tasks, which should address the activities that affect the safety or integrity of the pipeline and the appropriate codes, standards, and policies.

Fault Tree Task Identification Process

The other method is the Fault Tree Task Identification Process, an analysis tool that observes the relationship of different interacting events to produce an identifiable result. For the purposes of worker training, this task identification process is used to identify a particular threat to the pipeline. Following the nine threat groupings established by ASME B31.8S, the “top event” for each fault tree can be:

  1. natural hazards
  2. construction defects
  3. equipment failure
  4. internal corrosion
  5. incorrect operation
  6. stress corrosion cracking
  7. external corrosion
  8. manufacturing defects
  9. third-party damage

Such a method can be remarkably influential in limiting pipeline leaks or the impact of accidents, since it allows personnel to comprehend fully every influence on the pipeline’s structural integrity. And, in many cases, pipeline ruptures derive from several different causes. For example, many of the pipeline accidents that have occurred in recent history have resulted from natural hazards, such as floods from heavy rainfall. However, the main reason why these floods have been able to make such an impact of the safety of the pipelines is due to existing faults within the structures themselves.

ASME B31Q-2021: Pipeline Personnel Qualification is available on the ANSI Webstore.
