Background

This study aims to introduce the formulation of the regulation for the selection of respirators for accident preparedness chemicals (APCs) according to chemical workplace situations and to determine on-site applicability.

Methods

Workplaces were grouped into seven work categories, and APCs were classified into six groups to select adequate respirators. A survey was conducted to enhance the understanding of work situations and adequate respirators. The total number of subjects surveyed in 2018 was 201 managers and handlers, and that in 2019 was 91 handlers and 204 managers.

Results

Adequate respirators were allocated to each cell using the matrix method. The study observed an overall lack of understanding of work situations, especially in the operation of open devices, which was the highest at 32.7%. Despite its implementation in 2015, 17.6% and 25.0% of the managers and APCs handlers, respectively, were unaware of the regulations for selecting respirators. Only 70.4% of the APCs handler wore respirators in compliance with regulations.

Conclusion

The method for selecting respirators according to work situations using the matrix method is considered reasonable. Thus, this study suggests that the development of educational contents and reinforcing education should be essential steps to increasing awareness of regulations.

根据工作情况和现场适用性选择佩戴呼吸器的指南

背景

本研究旨在根据化学工作场所的情况，介绍事故准备化学品（APC）呼吸器选择法规的制定，并确定现场适用性。

方法

工作场所分为七个工作类别，APC 分为六组以选择足够的呼吸器。进行了一项调查，以加强对工作情况和适当呼吸器的了解。2018年被调查对象总数为201名管理者和从业人员，2019年为91名从业人员和204名管理者。

结果

使用矩阵方法为每个单元分配足够的呼吸器。该研究观察到总体上缺乏对工作情况的了解，尤其是在开放式设备的操作方面，这一比例最高，为 32.7%。尽管在 2015 年实施，但分别有 17.6% 和 25.0% 的管理人员和 APC 处理人员不了解选择呼吸器的规定。只有 70.4% 的 APC 处理人员佩戴了符合规定的呼吸器。

结论

采用矩阵法根据工作情况选择呼吸器的方法被认为是合理的。因此，本研究表明，发展教育内容和加强教育应该是提高法规意识的必要步骤。
