Medical and Industrial Gas Cylinders - Oxygen, Nitrogen, and Carbon Dioxide #3578635 (License: Personal Use)

This flat-style illustration shows three standard compressed gas cylinders, each color-coded and labeled per international safety standards: red for oxygen (O₂), blue for nitrogen (N₂), and gray for carbon dioxide (CO₂). The design emphasizes quick visual identification to prevent hazardous mix-ups in clinical, lab, or manufacturing environments. Each cylinder features a valve cap and base, rendered with subtle shadows for depth against a vibrant yellow backdrop.

Used on educational, safety training, or supplier web pages to illustrate gas identification, hazard awareness, or product catalogs. Matches user intent for learning about gas storage, handling protocols, or purchasing industrial gases.
