What must be kept at all times for FDNY use regarding standpipe systems?

Maintaining the standpipe systems in "ready" mode at all times is essential for ensuring that they are fully operational and accessible for fire service personnel during an emergency. This mode means that the systems are pressurized and can immediately supply water when needed, which is critical for firefighting efforts.

The readiness of standpipe systems is pivotal in construction sites and other buildings because in the event of a fire, firefighters rely on these systems to deliver water quickly and efficiently. Any delay in accessing water could lead to catastrophic consequences, potentially endangering lives and property.

Additionally, keeping the standpipe systems in "ready" mode aligns with fire safety regulations and standards set by firefighting authorities, including the FDNY. This requirement is aimed at ensuring that infrastructure is consistently prepared for emergency situations, thereby enhancing overall safety in construction and urban environments.
