呼吸性危害 可分为二大类型:空气污染或缺氧。 当存在空气污染,例如有石棉尘,必须测定其实际浓度。对于石棉尘,如同其他许多种类的空气污染物一样,必须首先采用工程技术控制来解决。 对于石棉尘问题,可采用在发尘点装置排风设备,密闭或半密闭式地处理物料,或者湿 Respiratory hazards can be divided into two major types: air pollution or lack of oxygen. When there is air pollution, such as asbestos dust, its actual concentration must be determined. Asbestos dust, like many other types of air pollutants, must first be addressed by engineering controls. For asbestos dust problems, the device can be used in the hair dust exhaust device, airtight or semi-closed treatment of materials, or wet
