A Y-Ton cylinder is used to store chemicals such as which substances?

• A. Oxygen and Nitrogen
• B. Hydrogen and Helium
• C. Silane and Phosphine
• D. Chlorine and Ammonia

Answer: (C)

Some gases are so reactive with air that they can ignite spontaneously if they come into contact with oxygen or moisture. For these highly reactive, pyrophoric gases, storage and transfer require special cylinder configurations that limit air exposure, such as a Y-tube cylinder. Silane and phosphine are classic examples of pyrophoric gases; they can ignite on contact with air and therefore are stored in systems designed to keep them inert and to control the release of gas without letting air in. That’s why this pair fits the scenario best. Oxygen and nitrogen are ordinary industrial gases stored in standard cylinders. Hydrogen and helium are generally non-pyrophoric (hydrogen is flammable, but not spontaneously igniting in air under normal storage conditions). Chlorine and ammonia are toxic and corrosive, with their own stringent storage needs, but they do not require the same Y-tube approach used for pyrophoric gases like silane and phosphine.
