What color and marking identifies the fluid lines that carry the fire extinguishing agent in an aircraft?

• A. Brown tape with a series of diamonds.
• B. Blue stripes.
• C. Green tape with diamonds.
• D. Red tracer lines.

Answer: (C)

Color and marking on aircraft fluid lines serve as a quick, universal language for maintenance crews. The lines that carry the fire-extinguishing agent are identified by green tape with diamond markings. The green color signals fire protection-related components, while the diamond pattern specifically flags lines that carry extinguishing agent, making them easy to spot at a glance and during servicing. This helps prevent confusion with other fluid systems and ensures technicians handle these lines safely, such as when inspecting, refilling, or replacing components. Other color patterns don’t match this standard combination, so green with diamonds is the clear, recognizable cue for fire-extinguishing lines.
