Which color corresponds to Helium?

Which color corresponds to Helium?

• A. Black
• B. Brown
• C. Blue
• D. Gray

Answer: (B)

Color coding of compressed gas cylinders is all about quick, safe identification of contents in the clinical environment. Each gas is assigned a distinct color on the cylinder so you can recognize it at a glance, reducing the risk of mixing gases during setup or during emergencies. In the system used for this question, helium is represented by blue. That makes a blue cylinder the telltale sign of helium, which is important for planning therapies like heliox or any situation where a helium-containing mixture is needed. The other colors listed—black, brown, gray—do not correspond to helium in this standard, so they would indicate different gases. Always confirm by reading the label as well, since color standards can vary by region.
