The Use of Infrared Emission Detection and Fugitive Emission Quantification Technologies as a Basis for Hazardous Area Classification Design

The use of nondispersive infrared (NDIR) detection technology as a basis for a hazardous area classification is described. Methods for identifying fugitive emission leaks using NDIR technology, quantifying leak data, and applying the results to document the basis for a hazardous area classification are presented. Limitations associated with the technology are also defined. A case history of a gas and oil production facility is provided to illustrate how a hazardous area classification design may be implemented using the technology.
