目的通过调查某区3家电信研发企业作业场所环境情况及其职业人群的不良感觉,了解当前电信研发企业作业场所环境状况及作业人员的主观感受。方法根据国家标准方法对作业场所内微波辐射、甲醛、二氧化碳及可吸入颗粒物等指标进行测定,并抽取121名职员进行主观感受调查。结果微波辐射检测合格率94.9%,甲醛检测合格率95.2%,可吸入颗粒物(PM10)检测合格率88.6%,二氧化碳检测合格率98.6%,新风量检测合格率81.9%,相对湿度检测合格率83.3%,不良主观感觉调查结果基本能验证实验室检测结果。结论虽然当前3家电信研发企业作业场所室内空气状况尚可,但在职员的主观感受上满意度有待提高,需加强管理、维护。
Objective To investigate the environmental conditions of workplaces and the subjective feelings of operators by investigating the environmental conditions at workplaces of three telecom research and development enterprises and the bad feelings of their working population in a certain area. Methods According to the national standard method, the microwave irradiation, formaldehyde, carbon dioxide and respirable particulate matter in the workplace were measured, and 121 staff members were selected for subjective feelings investigation. Results The passing rate of microwave radiation test was 94.9%, the pass rate of formaldehyde test was 95.2%, the pass rate of PM10 test was 88.6%, the pass rate of carbon dioxide test was 98.6%, the fresh air rate was 81.9% and the relative humidity was 83.3% , Poor subjective feeling survey results can basically verify the laboratory test results. Conclusion Although the indoor air condition of the three telecommunication research and development enterprises’ workplaces is acceptable at present, their subjective feelings of satisfaction need to be improved. Management and maintenance should be strengthened.
