This study was carried out to evaluated the actual conditions of working environment and health status of workers and search more effective health management method of workers in some dyeing factories. This study was conducted from April 1 to
October
30, 1992, for 426 workers in two dyeing factories and anelectric wire making factories.
Among 324 workers in two dyeing factories, 57.2% were male and 42.5% were female. Most of the engaged workers had less than 2 years of working carrier and aged 30 years or below. The used chemical substances exceeding 1 ton per a month were
sodium
hydroxide(NaOH), hydrogen peroxide (H2O2), sodium cholrite (NaClO), sodium sulfate(NaSO4), sodium carbonate (Na2CO3), and sodium hydrosulfite (Na2S2O4). The used chemical dyes exceeding 100kg per a month were suncion blue H-ERD, levafix brilliant
red
E-4BA. Suncion yellow E-3G, and remazol black B. As the allowable exposure time by governmental threshold limit values to industrial noise levels is 90 dBA for 8 hours. Average noise levels of the individual plants were ranged from 75 to 95db(A).
The
TLV for total cotton dust is 2.0mg/m*. Average cotton-dust concetration in these working environmental air were ranging from 0.2-1.3mg/m*. The TLV chlorine. Acetic acid and formic acid are 1 ppm, 10 ppm & 5ppm, respectively. The range of
chlorine,
and
acetic and formic acid concentration in these working environmental air were detected 0.2-1.6 ppm and at trace level. The accident by chemical substances and dyes was not found on these working environment.
From the physical examination and Todai Health Index scores results. There was no significant correlation between the used chemical substances and the diseases, such as bronchial asthma, other hyperreactive respiratory diseases and contact
dermatitis.
It was suggested that long term survey should de perfomed to detect the occupational health problem on these working environment.
