Which chemicals are typically stored in a Y-Ton cylinder?

Which chemicals are typically stored in a Y-Ton cylinder?

• A. Silane and Phosphine
• B. Oxygen and Nitrogen
• C. Water and Freon
• D. Helium and Neon

Answer: (A)

This question tests knowledge of why certain gas cylinders are used for particular chemicals. Y-Ton cylinders are a specialized type used for highly reactive, toxic gases that can pose ignition or contamination risks if exposed to air or moisture. Silane and phosphine fit this profile: both are extremely reactive and can be hazardous to handle, so they’re stored in a cylinder design that helps keep them isolated from air and moisture and that uses compatible materials and fittings. Oxygen and nitrogen are common industrial gases that are typically kept in standard high-pressure cylinders, not in Y-Ton types. Water and Freon are liquids or refrigerants, not the reactive gases typically paired with a Y-Ton. Helium and neon are inert noble gases and also do not require the special protections of a Y-Ton.
