Standpipe system piping subject to freezing temperatures should be protected using antifreeze solutions.

Standpipe system piping subject to freezing temperatures should be protected using antifreeze solutions.

• A. True
• B. False
• C. Only when required by local code
• D. Never

Answer: (A)

Preventing freezing in standpipe piping is essential when that piping could be exposed to freezing temperatures. antifreeze solutions are used because they lower the freezing point of the liquid inside the pipes, reducing the chance that water inside the standpipe will freeze and block the line. This helps ensure that water can reach hose connections and be discharged when the system is activated. In practice, antifreeze used in fire protection piping is chosen for compatibility and safety, typically a non-toxic glycol such as propylene glycol, and must comply with the authority having jurisdiction and the applicable NFPA 14 requirements. This approach is a recognized method to protect dry or partially filled standpipe systems in cold environments, where other remedies like heating or insulation may not be sufficient or feasible. So, the statement is true: standpipe system piping that could freeze should be protected using antifreeze solutions, subject to proper material, concentration, and code requirements.
