Inspections and tests on regulators and relief valves is a Department of Transportation Compliance rule. The sections within the DOT manual stating the rule include 192.351 through 192.359, 192.751, 192.479, 192.481, 192.739, and 192.741. Keep in mind; these rules are the minimum required tests. Your Company or Regulatory Agency may be more stringent and require more or detailed testing. You must also keep in mind that the Manufacturer of your equipment will also provide a guideline pertaining to maintenance. These tests are not only required for safe, reliable service to your Customers, but also could be used in any legal proceeding for documentation and purpose.

There are many important tasks and precautionary measures to perform and inform before you actually start the actual testing. Listing these items and performing a checklist could provide to be a reminder. Some station designs and equipment installations may require more than one person to perform a safe, reliable test. Plan the procedure within your work group, be sure all safety equipment and notifications are in place, perform the task and document the results according to your Company procedures.

We must also be aware of the Operator Qualifications rule. The Technician must be completely OQ qualified and have the proof of all the required OQ tests readily accessible.

Most importantly, these required DOT and Regulatory Agency tests are done for the safety of the system, customers and you.
