2020年靖西市工作场所职业病危害因素监测结果分析

Analysis on monitoring results of occupational hazards in workplaces in Jingxi City 2020

目的对2020年靖西市30家企业职业病危害因素监测的结果进行分析,探究职业病危害因素防控的关键控制点。方法2020年对靖西市重点行业30家企业的重点岗位进行粉尘、苯、噪声、锰及其化合物等职业病危害因素进行检测,应用SPSS 18.0统计软件进行数据统计,采用χ^(2)检验分析超标率的差异性,以P<0.05为差异有统计学意义。结果2020年监测靖西市企业工作场所30家,职业病危害因素监测点数264个,超标点24个,总超标率为9.09%,其中噪声超标率为14.58%,化学因素超标率为6.25%,粉尘的超标率为1.14%。不同行业企业和不同种类职业病危害因素超标率差异有统计学意义(χ^(2)值分别为21.628、12.306,P均<0.05),不同规模企业其超标率差异无统计学意义(χ^(2)=3.825,P=0.281)。结论靖西市石材加工行业、黑色金属冶炼与压延加工业工作场所职业病危害因素超标率较高,关键控制因素是噪声、锰及其化合物。建议企业进一步完善防护措施及个人防护用品管理,提高工人自我防护意识和养成健康职业习惯。

Objective To analyze the monitoring results of occupational disease hazards in 30 enterprises in Jingxi City in 2020,and to explore the key control points for the prevention and control of occupational disease hazards.Methods In 2020,the key positions of 30 key enterprises in Jingxi City were detected for occupational disease hazards such as dust,benzene,noise,manganese and its compounds,and SPSS 18.0 statistical software was used for data statistics.Chi-square test was used to analyze the difference of the exceeding standard rates,and the difference P<0.05 was statistically significant.Results In 2020,workplaces of 30 enterprises in Jingxi City were monitored,with 264 monitoring points for occupational disease hazard factors,and 24 points were exceeding the standard.The total exceeding standard rate was 9.09%,of which the exceeding standard rate of noise was 14.58%,the exceeding standard rate of chemical factors was 6.25%,and the exceeding standard rate of dust was 1.14%.The differences in the exceeding standard rates of occupational disease hazard factors of different industries and different types were statistically significant(χ^(2)=21.628,12.306,respectively,all P<0.05),while the difference in the exceeding standard rate of different scale enterprises was not statistically significant(χ^(2)=3.825,P=0.281).Conclusions The exceeding standard rates of occupational disease hazard factors in stone processing industry,ferrous metal smelting and rolling processing industry were high in Jingxi City.The key control factors were noise,manganese and its compounds.It is recommended that enterprises should further improve protective measures and the management of personal protective equipment,and improve workers’awareness of self-protection and develop their healthy occupational habits.
