National concordance standards for respiratory protection during abrasive blasting have existed for more than 50 years; however, these standards have not kept pace with advances in blast equipment, have not provided realistic estimates of expected protection in the workplace, and have been misused by manufacturers and distributors of respiratory protective equipment who have assured, through sales literature, that the equipment is acceptable for conditions under which they have never been tested. This situation has contributed to exposure of sandblasters to hazardous levels of respirable free silica, and is reviewed here to prevent a continuation of the incompatibility of these and other standards for respiratory protection with the actual exposures to various noxious inhalants in the workplace.
关于喷砂作业时呼吸防护的国家一致性标准已经存在了50多年；然而，这些标准未能跟上喷砂设备的进步，没有对工作场所的预期防护效果提供实际的评估，并且被呼吸防护设备的制造商和经销商滥用，他们通过销售宣传资料保证这些设备适用于从未经过测试的条件。这种情况导致喷砂工人暴露于可吸入游离二氧化硅的危险水平，本文对此进行综述，以防止这些及其他呼吸防护标准与工作场所实际接触各种有害吸入物的情况继续不匹配。
