Which marking indicates a flammable refrigerant in cylinders?

• A. Blue band on the bottom
• B. Green stripe on the cap
• C. Red band on the top of the container
• D. Yellow label on the side

Answer: (C)

Reading cylinder markings helps you quickly identify hazards so you can handle the cylinder safely. A red band on the top of a refrigerant cylinder signals that the contents are flammable. This high-visibility top-band marking is designed to be easily seen during storage and handling, so you can take precautions like avoiding ignition sources and ensuring proper ventilation. The other marks—blue band on the bottom, green stripe on the cap, or a yellow label on the side—do not indicate flammability in this standard marking system. In short, the red top band is the cue that the refrigerant is flammable and requires appropriate safety measures.
