Sampling Equipment - Personal Samplers: Cotton is to bo dcleiinined primarily with tin* personal sampler attached to the workman's clothing with the face of the filter pointing down. The filter should not be covered. Our experience is that at least a 4- and prefer ably a 6-hour sample (at 1.5 l/m) is required in a textile plant opening or carding area to obtain reliable results. A preweighed filter (0.01 tug) should be used and reweighed to the same accuracy. There is no ceiling or any limit on excursions. Because of the nature of both the sampling method and the development of byssinosis, it is neither desirable nor possible to get grab samples.
