Fugitive and diffuse emissions of common concern to industry sectors - Detection of fugitive emission of vapours generating from equipment and piping leaks using Optical Gas Imaging (OGI)

Scope

This document specifies the performance requirements, test procedures, operator proficiency, and operational requirements for a technique known as optical gas imaging (OGI).
This document applies to the use of OGI cameras as part of an LDAR programme. It specifies the scope of application, performance requirements for OGI equipment and QA/QC procedures.
This document focuses on LDAR programmes, applied to VOCs (including methane), but a similar approach could be applied to other compounds that have IR spectral properties that enable visualization, by adapting the selection of OGI cameras having a detector with a different bandwidth.
Different types of technologies for OGI camera exist on the market, such as detectors which are either cooled or uncooled, as well as active and passive OGI cameras. However, this document focuses on the utilization of the most commonly utilized technology, the passive OGI cameras. Despite this, a similar approach could be applied to the use of active OGI cameras.
