Which features of high-rise buildings may pose problems for firefighters and MPOs?

High-rise buildings present unique challenges for firefighters and Mobile Pump Operators (MPOs), and option A highlights several critical issues that can complicate firefighting efforts in such structures.

Pressure reducing valves (PRVs) and pressure relief devices (PRDs) are integral components in modern high-rise fire protection systems. These devices regulate water pressure in the system to ensure that fire suppression systems function effectively. However, if these devices malfunction or are not properly set, they may deliver insufficient water pressure to fire hoses, leading to ineffective firefighting efforts.

Falling glass from windows poses a significant hazard during a fire, as it can injure firefighters or impede their ability to access certain areas of the building. High-rise fires can lead to broken windows due to heat, creating a dangerous environment around the base of the building.

Occlusions in the fire protection systems, whether due to debris or blockages in pipes, can reduce the effectiveness of sprinkler systems or hose lines, hampering the firefighting response. Being aware of these potential problems is crucial for MPOs to ensure they have the right strategies and equipment in place before tackling a fire in a high-rise setting.

Understanding these challenges is essential for effective firefighting operations in high-rise buildings, as they can significantly impact
