Textile Dye Weighing Monitoring Study. Supplement

摘要

Dye weighers in textile dyeing and printing plants are involved in the weighing and transfer of relatively small quantities of numerous powder dyes and other chemicals. This results in a potential exposure to a diverse range of chemicals which exhibit a broad spectrum of toxicological properties. In order to gain more detailed information about workplace exposure to powder dyes, a study has been conducted to measure concentrations of dyes in the workplace air, and to characterize worker activities and industrial hygiene practices. The study was unique in that both government (U.S. Environmental Protection Agency) and industry (American Textile Manufacturers Institute and Ecological and Toxicological Association of Dyestuffs Manufacturing Industry) collaborated on an impartial basis and the dyehouses studies participated on a strictly voluntary basis. The document contains quality assurance project plans, data quality objectives, letters to encourage plant participation, first phase questionnaire, and in-plant questionnaire.
