刺激性气体是一大类最常见的、以呼吸系统为主要靶器官的职业病危害因素,随着生产环境的不断改善,刺激性气体慢性呼吸道毒性作用日益受到关注。由于缺乏相应的诊断标准,长期从事刺激性气体作业的职工所患的“职业性慢性呼吸系统疾病”得不到明确诊断,从而不能及时脱离刺激性气? Irritant gases are the most common occupational hazards with the respiratory system as the main target organ. As the production environment continues to improve, the toxic effects of irritating gases on chronic respiratory tract are gaining more and more attention. Due to the lack of corresponding diagnostic criteria, “occupational chronic respiratory diseases” suffered by workers who have long been engaged in irritating gas operations can not be clearly diagnosed and thus can not be promptly separated from irritating gases.
