What factor can deteriorate the performance of a standpipe system over time?

Extreme temperature fluctuations can lead to various issues that negatively impact the performance of a standpipe system over time. For instance, rapid changes in temperature can cause materials such as pipes and seals to expand and contract. This ongoing stress can lead to cracks, leaks, or other failures in the piping system. Moreover, freezing temperatures can result in the accumulation of ice within the pipes, which can obstruct the flow of water and potentially damage the system. As a result, consistent exposure to extreme temperatures can compromise the reliability of the standpipe system when it's needed most during a fire emergency.

While increased usage of stairs may impact the physical strain on firefighters, it does not directly affect the mechanical integrity of the standpipe system itself. The installation of additional outlets can enhance functionality when properly managed, and frequent updates to fire codes ensure that the systems meet current safety standards rather than deteriorate their performance. Thus, the implications of temperature extremes are more pronounced in terms of potential system failure and reduced performance.
