Class 2 Standpipe is designed for use by building occupants and is equipped with outlets of what size?

• A. 2 inch
• B. 1/2 inch
• C. 1 1/2 inch
• D. 3 inch

Answer: (C)

Standpipes intended for building occupants use are designed with smaller, more manageable outlets to fit standard handlines carried by occupants. These outlets are one-and-a-half inches in diameter. That size balances ease of handling for nonfirefighters with enough flow to begin an interior attack before firefighters arrive. In contrast, outlets on standpipes for fire department use are larger (two-and-a-half inches), which is why this class of system is specifically identified for occupant use with the smaller outlet size.
