Branch (lateral) lines are defined as piping sections that serve a room or group of rooms on the same story.

• A. A single room
• B. A room or group of rooms on the same story
• C. Outdoor distribution
• D. The building's main trunk

Answer: (D)

Branch lines are the part of a medical gas distribution that carries the supply from the main distribution to the point of use on a specific floor, serving either a single room or a group of rooms on that same story. This keeps each floor fed from the main trunk through smaller, floor-specific branches, making it possible to supply multiple outlets within that level without delivering gas all the way from the building’s base. The main trunk is the primary vertical feed, while outdoor distribution handles piping outside the building. So, branch lines fit the description of serving a room or group of rooms on the same story.
