NISOH has recommended a Standard for Occupational Exposure to crystalline silica to OSHA with documentation based on dust count studies relating to health effects. This standard dictates sampling by mass respirable method only. A dual standard as in ACGIH-TLV list should be promulgated by OSHA which includes the dust count standard.
职业安全与健康协会(NIOSH)已向职业安全与健康管理局(OSHA)推荐了一项关于职业接触结晶硅石的标准,并附上了基于与健康影响相关的粉尘计数研究的文件。该标准规定仅采用可吸入质量法进行采样。职业安全与健康管理局应颁布一项类似于美国政府工业卫生学家会议(ACGIH)阈限值(TLV)列表中的双重标准,其中包括粉尘计数标准。
