Guidelines for the selection of hydrogen gas inhalers based on hydrogen explosion accidents.
Despite the fact that we have reported on the dangers of the explosion of hydrogen gas inhalers, hydrogen gas inhalers with explosive hazards are, as a matter of fact, still being sold today. In this study, we investigated past reports of hydrogen gas inhaler explosion accidents to clarify the causes of these explosion incidents. As a result of this investigation, we found that the central cause was the leakage of hydrogen gas inside the hydrogen gas inhaler. Although it is said that the explosive concentration of hydrogen is between 10% and 75%, and that the gas does not explode above 75% due to the lack of oxygen, we confirmed through a series of ignition experiments that explosions can occur even in hydrogen gas inhalers that produce 100% hydrogen gas. Some manufacturers of such highly concentrated hydrogen gas inhalers claim that the high concentration and purity of hydrogen is safe and that there is no risk of explosion. We believe that manufacturing or selling such products that pose a risk of explosion or detonation is a violation of social justice. This paper presents ideas for selecting safe hydrogen gas inhalers based on a survey of past accident cases.
期刊介绍:
Medical Gas Research is an open access journal which publishes basic, translational, and clinical research focusing on the neurobiology as well as multidisciplinary aspects of medical gas research and their applications to related disorders. The journal covers all areas of medical gas research, but also has several special sections. Authors can submit directly to these sections, whose peer-review process is overseen by our distinguished Section Editors: Inert gases - Edited by Xuejun Sun and Mark Coburn, Gasotransmitters - Edited by Atsunori Nakao and John Calvert, Oxygen and diving medicine - Edited by Daniel Rossignol and Ke Jian Liu, Anesthetic gases - Edited by Richard Applegate and Zhongcong Xie, Medical gas in other fields of biology - Edited by John Zhang. Medical gas is a large family including oxygen, hydrogen, carbon monoxide, carbon dioxide, nitrogen, xenon, hydrogen sulfide, nitrous oxide, carbon disulfide, argon, helium and other noble gases. These medical gases are used in multiple fields of clinical practice and basic science research including anesthesiology, hyperbaric oxygen medicine, diving medicine, internal medicine, emergency medicine, surgery, and many basic sciences disciplines such as physiology, pharmacology, biochemistry, microbiology and neurosciences. Due to the unique nature of medical gas practice, Medical Gas Research will serve as an information platform for educational and technological advances in the field of medical gas.
