洁净车间的环境卫生现状及预防对策

Hygienic Status of the Clean Workshops and Preventive Countermeasures

目的为保障洁净车间工作人员的身体健康，对日照市14家不同行业的洁净车问进行卫生学调查，针对存在问题，制定有效预防控制措施。方法以洁净车间为测试组，空调非洁净车间为Ⅲ性对照，室外环境大气为阴性对照。进行微小气候和卫生指标检测并对结果进行比较分析。结果洁净车间的湿度波动（38％～69．9％）和霉菌总数大于非洁净检测点，空气中负离子均值低于室外空气（P〈0．01），与普通空调车间相比差异无统计学意义（P〉0．05）。结论洁净车间的温度、湿度是引起工作人员身体健康危害的主要原因，某些病原微生物的存在应引起高度重视。

[Objective] To protect the physical health of the workers in the clean workshops, find hygienic problems and establish preventive countermeasures. [ Methods ] Clean workshops were taken as the test group, air - conditioned non - clean workshops were taken as the positive control group and the outdoor air was taken as the negative control group; detection was made on the microcfimate and hygienic indexes; comparison and analysis were made on the Results. [ Results] The humidity （38% -69.9% ） and total mould counting of the clean workshops were higher than that of the non - clean group ; the mean value of the negative ion in the clean workshops was lower than that of the outdoor air （ P 〈 0.01 ） , however showed no significant difference with that of the common air - conditioned workshops （ P 〉 0.05 ）. [ Conclusion ] The temperature and humidity of the clean workshops are the major reasons for the physical damages of the workers ; great emphasis should be put on the pathogens.
