Despite prior warnings about the hazards associated with hydrogen gas inhalers, inhalers carrying explosive risks are still available in the market. This study delves into past incidents of hydrogen gas inhaler explosions to identify the root causes behind these accidents. The investigation revealed that the primary factor contributing to these explosions is the leakage of hydrogen gas within the inhaler. While it is commonly believed that hydrogen is explosively concentrated between 10% and 75%, and no explosion occurs above 75% due to oxygen deficiency, ignition experiments demonstrated that explosions can happen even in inhalers producing 100% hydrogen gas. Some manufacturers argue that the high concentration and purity of hydrogen are safe and devoid of explosion risks. The assertion is that producing or selling such products, which pose a threat of explosion or detonation, goes against principles of social justice. This paper provides insights for choosing safe hydrogen gas inhalers based on an analysis of past accident cases.
儘管先前已對氫氣吸入器存在的危險進行警告，市場上仍然有帶有爆炸風險的吸入器。這項研究深入探討了過去的氫氣吸入器爆炸事件，以找出這些事故背後的根本原因。調查顯示，導致這些爆炸的主要因素是吸入器內氫氣的泄漏。儘管一般認為氫氣的爆炸濃度在10%到75%之間，且由於缺乏氧氣，在75%以上的濃度不會爆炸，但點火實驗表明，即使在生成100%氫氣的吸入器中，也可能發生爆炸。一些製造商主張高濃度和高純度的氫是安全的，不存在爆炸風險。主張生產或銷售可能爆炸或引爆風險的產品違反社會公正原則。本文通過分析過去事故案例提供了選擇安全氫氣吸入器的見解。
