| dbo:abstract | سلامة الهيدروجين تغطي سلامة الهيدروجين الإنتاج الآمن ومناولة واستخدام الهيدروجين - وخاصة وقود غاز الهيدروجين والهيدروجين السائل. حيث يكون القلق الرئيسي في العمل مع الهيدروجين هو القابلية للاشتعال. (ar) La seguretat de l'hidrogen tracta la producció segura, el manejament i l'ús de l'hidrogen. Aquest element posa uns reptes únics a causa de la facilitat que té de fugues, d'ignició a baixa energia, la seva flotabilitat i la seva capacitat per fragilitzar metalls. L'hidrogen líquid encara té més complicacions, ja que és encara més dens i es necessita una temperatura extremadament baixa per mantenir-lo en forma líquida. (ca) La seguridad de hidrógeno cubre la producción, manejo y uso seguro del hidrógeno. El hidrógeno presenta desafíos únicos debido a la facilidad con que se producen fugas, ignición a baja-energía, amplia variedad de mezclas aire-combustible, flotabilidad y su habilidad para lo que se debe considerar para asegurar operaciones seguras. El hidrógeno líquido posee desafíos adicionales debido al aumento de su densidad y extremadamente bajas temperaturas que se necesitan para mantenerlo en estado líquido. El hidrógeno es usado como una materia prima en procesos industriales incluyendo la producción de amonio y metanol, y la refrigeración de generadores eléctricos en centrales de generación de energía eléctrica. También es usado como agente de saturación para formación de mantecas en aceites insaturados, esto conduce a la fabricación de margarinas y aceites en forma industrial. (es) Hydrogen safety covers the safe production, handling and use of hydrogen, particularly hydrogen gas fuel and liquid hydrogen. Hydrogen possesses the NFPA 704's highest rating of 4 on the flammability scale because it is flammable when mixed even in small amounts with ordinary air; ignition can occur at a volumetric ratio of hydrogen to air as low as 4% due to the oxygen in the air and the simplicity and chemical properties of the reaction. However, hydrogen has no rating for innate hazard for reactivity or toxicity. The storage and use of hydrogen poses unique challenges due to its ease of leaking as a gaseous fuel, low-energy ignition, wide range of combustible fuel-air mixtures, buoyancy, and its ability to embrittle metals that must be accounted for to ensure safe operation. Liquid hydrogen poses additional challenges due to its increased density and the extremely low temperatures needed to keep it in liquid form. Moreover, its demand and use in industry—as rocket fuel, alternative energy storage source, coolant for electric generators in power stations, a feedstock in industrial and chemical processes including production of ammonia and methanol, etc.—has continued to increase, which has led to the increased importance of considerations of safety protocols in producing, storing, transferring, and using hydrogen.
