A class 2 standpipe must be what?

A Class 2 standpipe is designed to provide a certain level of safety and is typically divided into sections for several important reasons. This division helps in managing the water supply more effectively, allowing for maintenance and inspections to be conducted without affecting the entire system. By segmenting the standpipe, it allows firefighters to quickly access water in specific areas of a building or structure, enhancing both safety and efficiency during an emergency response. Additionally, sections can facilitate easier repairs or upgrades without disrupting the entire standpipe system, ensuring that there is always a portion of the system operational for firefighting efforts.
