What does an outlet class indicate in standpipe labeling?

• A. They indicate the type of outlet (I, II, III) available.
• B. They indicate the color of the water.
• C. They indicate the manufacturer.
• D. They indicate the building's occupancy type.

Answer: (A)

The main idea is that standpipe outlet labeling tells you what kind of outlet is present at that point. An outlet class indicates the type of outlet (I, II, III) available, which corresponds to the hose connection size and who should use it. Class I outlets are a 2.5-inch connection for fire department attack lines, Class II outlets provide a 1.5-inch connection for occupant use with a preconnected hose, and Class III outlets offer both sizes for either occupants or firefighters. This labeling isn’t about water color, the manufacturer, or the building’s occupancy. So the label shows the specific outlet type available at that standpipe location.
