What is the consequence of exceeding the maximum psi in air-pressurized standpipes?

Exceeding the maximum psi in air-pressurized standpipes significantly increases the risk of system failure. Standpipes are designed to operate within specific pressure limits to ensure the integrity and safety of the entire system. When the pressure surpasses these limits, it can lead to mechanical failures, such as pipe rupture or failure of the connections and fittings. This not only compromises the standpipe system but also poses a safety risk to firefighters who rely on it for water supply. Additionally, excessive pressure can cause backflow issues or damage to the hose, leading to further complications during firefighting efforts. It is essential to maintain pressures within the recommended range to ensure the reliability and functionality of the standpipe system during emergency situations.
