eLearning Module: TM-12, Introduction to Periodic Requalification

The Compressed Gas Association (CGA) is excited to introduce TM-12, a new eLearning module that provides an essential introduction to the periodic requalification of compressed gas cylinders. This training is critical for maintaining the safety and integrity of cylinders used across various industries. The module covers the necessary steps, considerations, and testing methods that ensure cylinders meet current safety standards and regulations.

Why Periodic Requalification Matters

Periodic requalification of compressed gas cylinders is a crucial aspect of safety in the gas industry. Over time, cylinders are subjected to stresses that can compromise their structural integrity. Regular requalification helps detect any potential issues before they lead to failures, such as leaks or ruptures during pressurization. By adhering to these safety measures, organizations can prevent accidents, reduce operational risks, and comply with regulatory requirements.

What the Module Covers

1. Importance of Periodic Requalification:
This section emphasizes the significance of requalification in preventing cylinder failures, enhancing safety, and ensuring compliance with industry standards. It outlines how requalification helps extend the lifespan of cylinders and minimizes downtime.

2. Considerations for Requalification:
Here, users learn about the factors influencing the requalification process, such as the type of gas, cylinder material, frequency of use, and environmental exposure. Understanding these elements helps determine the most suitable testing method and schedule.

3. Steps in Requalification:
The module provides a step-by-step overview of the requalification process, from initial inspection to final approval. This section ensures that learners grasp the sequential nature of the process, highlighting critical checks and balances at each stage.

4. Methods of Requalification:
TM-12 dives into the various testing methods used in cylinder requalification, including:

  • Hydrostatic Testing: Measures a cylinder’s ability to withstand internal pressure without permanent deformation.
  • Proof Pressure Testing: A simplified pressure test that verifies the cylinder’s integrity without volume measurement.
  • Ultrasonic Examination: Uses sound waves to detect internal flaws that may not be visible externally.
  • Acoustic Emission Testing: Monitors sounds emitted by cylinders under stress to identify structural weaknesses.
  • Visual Inspection: Identifies external damage, corrosion, or defects that might affect cylinder performance.

5. Post-Requalification Procedures:
This section explains what happens after testing, such as marking approved cylinders, logging test results, and protocols for cylinders that fail the requalification criteria.

6. Additional Resources:
Learners have access to supplementary materials, including reference guides, industry standards, and links to CGA publications, enhancing their understanding of the requalification process.

Designed for Industry Professionals

TM-12 is designed for anyone involved in the handling, maintenance, or inspection of compressed gas cylinders. This training is particularly beneficial for new hires, safety officers, and maintenance personnel who need to understand the basics of cylinder safety and requalification. While this module provides a thorough introduction, it does not replace formal work instructions or standard operating procedures.

Access and Pricing

CGA members and GAWDA subscribers can access this training module for free, as part of their membership benefits. For non-members, access to TM-12 is available for $59, granting 90 days of access to complete the training.
