Class II standpipes serve a 1.5-inch fire hose connection and are typically found in cabinets. These are intended for trained occupant use and are spaced according to the hose length.

Standpipe systems in other areas at Park Street passed their most recent pressure tests between 2019 and 2021, according to the T spreadsheet, and another round of testing is due to begin next year.

Standpipes are often required by local fire codes or building codes for certain types of skyscrapers, other large structures, transit stations, or other transportation hubs, according to Puchovsky.
