一些大中企业自己成立了粉尘监测机构或配备了测尘人员,定期对本企业进行粉尘测试工作。这对贯彻预防为主,适时了解本企业粉尘危害,为改进防尘技术措施提供依据,都十分必要。但目前有些企业的粉尘自测工作还存在很多问题。主要表现在: 1、测尘人员技术素质差。有的测尘人员没有经过正规的技术培训,技术操作不合要求。如某厂测尘人员在称量滤膜时竟连同夹衬纸一起称,造成测尘结果经常出现“负值”。有的采样位置定得离尘源太远。
Some large and medium-sized enterprises set up their own dust monitoring agencies or equipped with dust inspectors who regularly carry out dust testing work for the enterprise. This is the implementation of prevention-based, timely understanding of the hazards of this enterprise dust, dust-proof technical measures to improve the provision of the basis are very necessary. However, there are still some problems with the self-testing of dust in some enterprises. Mainly in: 1, poor technical quality of personnel dust. Some people do not dust the formal technical training, technical operation is not satisfactory. If a factory dust measurement staff even in the weighing filter with the clamp liner together, resulting in dust results often appear “negative.” Some sampling locations set too far away from the dust source.
