The NIOSH Analytical Method 7400 for airborne fibers specifies the use of electrically conductive cowls for air sampling. Data collected from a number of laboratories indicate that a significant fraction of collected dust may be deposited on the inside of electrically conductive cowls during air sampling for man-made mineral fibers. The purpose of this article is to present a cowl rinsing procedure for airborne fiber sampling. This method is the consensus of an ad hoc group formed to evaluate existing cowl rinsing procedures. A number of issues related to cowl rinsing are also addressed.
