Booster Line is commonly referred to by what color name?

• A. Redline
• B. Blue Line
• C. Green Line
• D. Gold Line

Answer: (A)

Color coding helps firefighters identify equipment at a glance during drills and real fires. The booster line is a smaller, high‑pressure hose used to boost flow for fire attack, so it’s labeled with a standout color. In many training materials and departments, that color is red, referred to as the Redline. This makes the booster line easy to spot and differentiate from other lines that serve different purposes or pressures. While other color names exist for different lines in various curricula, they don’t apply to the booster line in this context. So the booster line is commonly called the Redline.
