Leaking equipment, such as pumps, valves, and jointed connections can be a large source for fugitive emissions of volatile compounds (VOC’s) and volatile hazardous air pollutants (VHAP’s). Fugitive emissions of these compounds can cause breathing difficulties for people in proximity to the source of the leak, and they may contribute to disease processes, including cancer.

Fugitive emissions are defined as any chemical in physical form that can leak unexpectedly from a facility or equipment. These emissions are important because they contribute significantly to greenhouse gases and global warming.

According to the US EPA (Environmental Protection Agency), valves are the single largest source of fugitive emissions of VOC’s and VHAP’s. Flanged connections are the second largest contributor. For both types of leaks, gaskets and packing have a key role to play in preventing fugitive emissions.

What is a Leak Detection and Repair program?

A Leak Detection and Repair (LDAR) program can help a company to reduce the incidence of fugitive emissions from equipment. Through an LDAR, a company can implement a structured formal process for monitoring equipment condition and preventing leaks before they occur.

An LDAR is an important component of any strategy for achieving zero emissions. With an LDAR, leaks from valves, flanged connections, and other sources can be detected early, leading to prompt repair.

How does an LDAR work?

The EPA has a publication, Leak Detection and Repair: A Best Practices Guide, which explains how companies can run an effective LDAR. The guide highlights five key elements of a good LDAR:
