Which cylinder type is used in this SCBA?

• A. Luxfer Cylinder
• B. Nelson Cylinder
• C. Airgas Cylinder
• D. Omega Cylinder

Answer: (A)

The important idea here is recognizing that SCBA cylinders are identified by their brand and the specific valve/interface they use, which must match the regulator and mounting on the SCBA. In the unit shown, the cylinder is a Luxfer, which is a widely used and compatible type for many fire-service SCBAs. The Luxfer cylinder branding and standard high-pressure cylinder construction align with the SCBA’s valve, neck, and overwrap design, making it the correct match for the pictured setup. Other brands—Nelson, Omega, or Airgas—also produce cylinders, but they’re not the ones depicted or specified for this particular SCBA model, as their valve interfaces, dimensions, or fittings may differ and wouldn’t be shown as the appropriate choice for this unit.
