Leak Detection and Repair is a crucial process. Fugitive emissions are unintended releases of gases or vapors from pressurized equipment, piping, or valves, which can contribute to air pollution and pose environmental and health risks.

The first step involves identifying equipment and components subject to leak detection, such as valves, pumps, connectors, and flanges. This is often done through site surveys, equipment tagging, and the use of infrared cameras or other detection devices.
Various methods are employed to detect leaks, including optical gas imaging (OGI), sniffing devices, acoustic leak detectors, and portable analyzers. These tools help pinpoint leaks accurately and efficiently.
Once a leak is detected, its size and severity are quantified. This may involve measuring the concentration of emissions, calculating emission rates, or assessing the leak's impact on air quality.
After quantification, leaks are prioritized based on factors such as emission rates, potential environmental impact, and safety considerations. Repairs are then scheduled and implemented promptly to minimize emissions.
Following repairs, the effectiveness of the corrective actions is verified through re-inspection and testing to ensure that leaks have been adequately addressed.
Comprehensive recordkeeping is essential for documenting LDAR activities, including leak detection results, repair actions, and compliance with regulatory requirements. Regular reporting to regulatory agencies may also be necessary to demonstrate compliance with emission limits and regulatory standards.
