【摘要】：[目的]了解人造矿物纤维(MMMF)企业工人粉尘暴露及其健康状况,为制定MMMF粉尘危害的预防控制措施提供参考。[方法]随机选择浙江省3家MMMF生产企业(玻璃纤维、耐火材料A,B)进行粉尘浓度检测,对497名接尘工人拍摄胸片,调查工人皮肤症状;同时选择某塑料企业同期体检的89人作为对照组,并对结果进行对比分析。[结果]玻璃纤维企业原料投料岗位个体采样的粉尘浓度达标率为80%,耐火陶瓷纤维A企业粉尘浓度均达标,耐火陶瓷纤维B企业的铺棉和切割工种定点采样的粉尘浓度达标率为33.3%。MMMF 3家企业接尘工人的皮肤刺激、皮肤瘙痒、皮肤红斑的检出率均高于对照组(P0.01);接触性皮炎的检出率为3.7%~4.6%。未有工人被诊断为尘肺病,耐火陶瓷纤维B企业有1人被诊断为尘肺病观察对象。[结论]耐火陶瓷纤维企业原料投料工种的粉尘浓度达标率较低,MMMF接触工人皮肤刺激、瘙痒、红斑、接触性皮炎检出率较高。
[Abstract]:[objective] to understand the dust exposure and health status of workers in MMMF enterprises, and to provide a reference for the prevention and control of MMMF dust hazards.[methods] three MMMF production enterprises (fiberglass, refractory) in Zhejiang Province were randomly selected to measure the dust concentration, and the chest radiographs were taken from 497 workers exposed to dust to investigate the skin symptoms of the workers.At the same time, 89 people were selected as control group, and the results were compared and analyzed.[results] the dust concentration reached the standard rate of 80%, and the dust concentration of refractory ceramic fiber A enterprise was up to the standard.The dust concentration reached the standard rate of cotton spreading and cutting in refractory ceramic fiber B enterprise. The detection rate of skin irritation, pruritus, erythema and contact dermatitis were higher than that of control group (P 0.01), and the detectable rate of contact dermatitis was 3.7% (4.6g).No worker has been diagnosed with pneumoconiosis, and one worker in Fire-resistant Ceramic Fiber B Enterprise has been diagnosed as an observation object of pneumoconiosis.[conclusion] the dust concentration of refractory ceramic fiber enterprises is lower than that of MMMF. The detection rate of skin irritation, pruritus, erythema and contact dermatitis in workers exposed to MMMF is higher.
