Frequently asked questions about Gas Leak Survey

What do gas leak grades mean?
The gas industry commonly classifies leaks into three grades, adapted from the GPTC/DOT-PHMSA framework used by pipeline operators: Grade 1 is a probable existing hazard requiring immediate action, Grade 2 is non-hazardous at the time of detection but should be scheduled for repair, and Grade 3 is non-hazardous and expected to remain so. This report records the grade assigned to each leak; a contractor working on customer-side piping should confirm exact repair timeframes with the local utility/AHJ, as these vary by jurisdiction.
How often should a gas leak survey be done?
Survey frequency depends on the system, occupancy and jurisdiction — periodic surveys are common for commercial and utility systems. The report supports an annual or scheduled survey cycle.
