Abstract: Selection of the most efficient type of instrument for detection of combustible gases depends on whether the leakage is on above ground or below ground systems. Other factors involved include type of combustible to be detected, sensitivity levels required to detect the leaks you want to be capable of detecting and type of sampling to be employed. Sampling may be accomplished by hand aspirator or pumps for positive sampling or by use of diffusion type detector heads. Following selection of the type of instrument to be employed, the calibration of the instrument must be tested with a known gas sample. Procedure for the use of instrument must also be established and the personnel who are to use the instruments must be thoroughly trained in the proper operation and maintenance of equipment.
