目的：了解石雕作业工人对职业危害的知晓度和防护行为。方法测定石雕加工过程中不同工艺流程的粉尘浓度和噪声强度,并随机抽取某石雕加工厂的60名男性石雕工人作为调查对象,采用自行设计的调查问卷对调查对象进行问卷调查。结果石雕作业环境中粉尘浓度最小为23.33 mg/m3,最大为125.33mg/m3,粒径低于5μm的呼吸性粉尘的构成比为66.0%~78.9%,噪声为90.0~104.0 dB(A)。工人对石雕作业的职业危害知晓度的调查显示,总体知晓度为18.33%~100.00%,其中对“粉尘可导致尘肺”的知晓度为38.33%,对“噪声可导致耳聋”的知晓度为70%；工人在石雕作业中针对危害因素采取的主动防护行为的调查,总体防护率为8.33%~76.67%,其中“工作时是否戴防尘口罩”防护率为8.33%,“工作中是否佩戴耳塞”的防护率为16.67%。结论石雕作业环境粉尘噪声为危害均较严重,工人对石雕作业危害知晓度较低,主动防护行为更低。

Objective To investigate the stone carving workers'awareness towards occupational hazards and their protective behavior.Methods The dust and noise level in the process of stone carving were measured.60 male workers were randomly selected as research objects,and a survey on their awareness and protective behavior were followed with questionnaires which was designed by ourselves.Results Dust concentration in the stone carv-ing environment was from 23.33 mg/m3 to 125.33mg/m3 .The constituent ratio of the respirable dust with <5μm was 66.0%~78.9% and the noise level was 90.0dB(A)~104.0dB(A).The survey on the awareness of workers towards the occupational hazards of stone carving showed that the total awareness rate was 18.33%~100.00%. Among them,the rate of “dust leading to pneumoconiosis”was 38.33%,while the rate of “noise leading to deaf”was 70%.The total workers'initiative protective rate against hazards of stone carving was 8.33%~76.67%.A-mong them,the rate of “working with anti-dust masks”was 8.33%,and the rate of “working with earplug”was 1 6 .6 7%.Conclusion The dust and noise in stone carving environment were serious.The workers'awareness to-wards occupational hazards of stone carving was low,and the initiative protective behaviors were lower.
