摘　　要：有限空间作业因其进出口狭窄、通风条件不足,常伴随着高浓度的窒息性气体,这些因素共同导致作业环境中氧气含量降低。当空气中的氧气含量降至16%以下时,人体便可能出现缺氧症状;若氧气含量进一步下降,可能导致意识障碍甚至死亡。近期,河北、陕西等地区有限空间作业事故频发,造成多人伤亡。针对有限空间作业中潜在的危害因素,提出了一系列安全防护措施。特别强调了正确使用呼吸器的重要性,以期减少此类事故的发生。The narrow inlet and outlet of a limited space,poor ventilation conditions,and high concentration of suffocating gases result in a decrease in oxygen content in the air.When the oxygen content is below 16%,people will experience symptoms of hypoxia;As the oxygen content continues to decrease,people may experience consciousness disorders and even lead to death.Recently,limited space work accidents have occurred frequently in Hebei,Shaanxi and other places,resulting in multiple deaths.This article will propose safety protection measures for the hazards present in confined space operations.Emphasize the correct use of respirators to avoid such accidents.
