Which of the following best describes a fire suppression system's function?

The primary function of a fire suppression system is to extinguish fires when they occur. This can involve a variety of methods including water sprinklers, foam systems, or specialized gases that are designed to put out flames effectively. Fire suppression systems are installed in buildings to quickly respond to fire incidents, minimizing damage, and enhancing safety for occupants.

While preventing fires from occurring is a critical aspect of overall fire safety, it falls under fire prevention measures, which are not the direct function of suppression systems. Smoke inhalation prevention is also important, but this is typically handled by smoke control systems rather than fire suppression systems. Additionally, providing oxygen to trapped individuals is not a function of fire suppression systems; in fact, during a fire, suppression systems often work to minimize the availability of oxygen to help extinguish the fire. Thus, the identification of extinguishing fires as the key role of a suppression system accurately reflects its designed purpose in fire safety protocols.
