How often should piping for combustible liquids be tested before use?

Piping for combustible liquids must be tested before being covered or placed in use to ensure that all components are functioning correctly and are free from leaks. This initial testing is crucial because it confirms the integrity of the piping system, which is essential for preventing accidents, spills, and hazardous situations once the system is operational.

Testing before use allows for the identification and correction of any issues that could compromise safety or performance. Regular monitoring and maintenance are important, but this specific testing must occur prior to any covering or use to verify that the installation meets safety standards and regulatory requirements. The process ensures that the system is safe for operation and minimizes the risk of incidents related to combustible liquids.

While ongoing inspections might be necessary due to the operational environment or after repairs, the critical step is the pre-use testing, which establishes a baseline of safety for the newly installed system.
