Abstract

The draft, "Revised Guide for Respirable Mass Sampling," prepared by the AIHA-ACGIH Aerosol Hazards Committee, recommends five respirable mass sampling devices that sample in accordance with the "Los Alamos" respirable dust criterion. The spectrum of recommended sampling rates for these devices ranges from 1.8 to 430. liters per minute. A study was conducted to determine if simultaneous measurements with these devices yielded comparable respirable mass concentrations. The penetration characteristics of the first stage separators were also evaluated and compared.

摘要

美国工业卫生协会-美国政府工业卫生学家会议气溶胶危害委员会编制的《可吸入颗粒物质量采样修订指南》草案推荐了五种符合“洛斯阿拉莫斯”可吸入粉尘标准进行采样的可吸入颗粒物质量采样设备。这些设备推荐的采样率范围为每分钟1.8至430升。开展了一项研究，以确定使用这些设备同时进行测量时是否能得出可比的可吸入颗粒物质量浓度。还对一级分离器的穿透特性进行了评估和比较。
