Control of Dust in a Textile Dyeing Operation

• Description:
  Dry powdered dyes of many chemical types are used extensively to color textiles. These dyes are typically provided in bulk drums holding up to several hundred pounds and are removed as needed in measured amounts. This "weight-out" operation is the time of greatest potential exposure to employees. Worker exposure to dye dust through breathing or skin contact can result in adverse health effects such as occupational asthma, eczema, and severe allergic reactions. NIOSH, in collaboration with the Ecological and Toxicological Association of Dye Manufacturers, conducted field evaluations to evaluate three dust control options. These were: 1) a down draft hood; 2) use of a "dedusting agent;" and 3) drum size. An experimental protocol was designed to look at each of these variables. Personal dust samples were collected with impingers to measure workers' exposure with the ventilation on and off, using dye with and without the de-dusting agent, and weighing from either a 55-gallon durm or a smaller drum (similar in diameter but shorter in height). All combinations of the three variables were evaluated yielding a total of 8 tests using a 2 X 2 X 2 factorial design. Multiple sets of the 8 test runs were conducted to give that statistical power required to make conclusions regarding the control techniques. All comparisons were made against a "baseline" test consisting of no ventilation, and transferring de-dusted dye from a large drum. When comparing the results of each test, the use of a downdraft hood and working with de-dusted dye from small drums showed the greatest reductions in dye dust concentrations.
