OBJECTIVE
Respirators are used to maintain work performance and protect against inhaled toxins. The study compared the effects of two commonly used respirator classes--dual cartridge half face mask (HFM) and filtering face piece (N95)--upon work productivity.
METHODS
107 volunteers performed eight simulated work tasks when using the HFM and N95 respirators. Tasks included several body positions, exertion levels, and concentration requirements. Objective measures of accuracy and speed were developed for each task. Scores for each task were based on the subject's rank among all subjects.
RESULTS
All subjects were capable of performing the tasks. There were no statistically significant differences between respirator types in either task performance metric.
CONCLUSIONS
Productivity impact can be measured effectively and should be considered as part of respirator design testing and when selecting the optimal respirator for a worker.
目的
呼吸器用于维持工作性能和防止吸入毒素。本研究比较了两种常用呼吸器类型——双罐半面罩（HFM）和过滤面罩（N95）——对工作效率的影响。
方法
107 名志愿者在使用 HFM 和 N95 呼吸器时完成了八项模拟工作任务。任务包括多种体位、用力水平和浓度要求。为每个任务制定了客观的准确性和速度测量标准。每个任务的得分基于所有受试者中的排名。
结果
所有受试者都能够完成任务。在任务绩效指标方面，两种呼吸器类型之间没有统计学上的显著差异。
结论
可以有效地衡量生产力的影响，并且应该在呼吸器设计测试以及为工人选择最佳呼吸器时考虑到这一点。
