The use of infrared emission detection and fugitive emission quantification technologies as a basis for hazardous area classification design

The use of Non-Dispersive 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.
