A standpipe system is defined as?

• A. A system of pipes installed in a building to provide water for fire fighting.
• B. A portable pump used on the street for firefighting.
• C. A hydrant within a yard only.
• D. A natural water source used for firefighting.

Answer: (A)

A standpipe system is a fixed network of pipes installed inside a building to supply water for firefighting, with outlets available at various floors for firefighters to connect hoses. This setup stays in place and is designed to deliver water quickly to different parts of the building, often connected to a building’s water supply and sometimes to a fire department connection.

That’s why the option describing a system of pipes inside a building dedicated to providing water for fighting fires is the best choice. It isn’t a portable pump used on the street, nor just a yard hydrant, nor a natural water source, all of which lack the fixed building-wide piping and built-in outlets that define a standpipe system.
