Hazard control effect of occupation disease at a float glass factory

Abstract

Objective To explore the hazard control effect of occupation disease at a float glass factory.Methods Occupational hygienic investigation,occupational hazards and protecting facilities for occupational hazards detection,and occupational health examination were used to evaluate the control effect of occupational hazards.Results The major hazard factors causing occupation diseases were dust,noise,high temperature,chemical toxicants (ammonia,carbon monoxide,carbon dioxide,nitrogen dioxide,sulfur dioxide,two tin oxide,and non-methane total hydrocarbon),and electromagnetic field.Free silica dust in 13 copies (SiO2) of contents was average (34.51 ± 27.38)％ (2.65％ ～ 71.74％).Total dust concentration was detected at 41 points,with a qualified rate of 95.12％ (39/41).The intensity of noise was detected at 32 points,with a qualified rate of 93.75％ (30/32).Chemical toxicant concentrations were detected at 66 points,with a qualified rate of 100.00％.High temperature test was carried out at 8 points,of which 4 points (50.00％) were over the occupation contact limiting value.The detection results of power frequency electric field strength were all qualified.The face velocity of occupation disease prevention facilities was 0.03 ～ 3.26 m/s.389 people took occupation health examination; no one were suspected with occupation disease,and 3 were found with high temperature or noise operation contraindication.Conclusions The occupation disease harm at chemical toxicants and power frequency electric field is controlled well.The control effect of dust and noise hazards is good.The harm of high temperature control effect is poor.Prevention and control work of high temperature,noise,and dust hazards needs to be enhanced.
