本文简述了国内外化学氧自救器的概况及我国研制符合国际标准的化学氧自救器的迫切性。重点讲述了我国首创的符合国际标准的OSR-30C型化学氧自救器及其关键部件-气流分配器和呼吸系统的结构特声、及主要技术参数，还对自救器所必需的检验手段-符合国际标准的自救器检验装置的建立做了论述，并对OSR-30C型自救器与国内外先进的自救器做了防护性能对比。
This article outlines the overview of chemical oxygen self-rescuer at home and abroad and the urgency of developing chemical oxygen self-rescuer in line with international standards. It focuses on the OSR-30C chemical oxygen self-rescuer and its key components, which are the first in our country, conform to the international standards - the structure of the gas flow distributor and respiratory system, and the main technical parameters, and also the necessary test methods for self-rescuer - The establishment of international standard self-rescuer test device is discussed, and the protective performance of OSR-30C self-rescuer and advanced self-rescuer at home and abroad are compared.
