What best describes a fire suppression system?

A fire suppression system is specifically designed to extinguish or control fires automatically. This system can include various components such as sprinklers, chemical agents, foam, or water mist, all intended to actively combat a fire when it occurs. The primary focus of such a system is to reduce the spread of fire and limit damage, potentially saving lives and property.

In contrast, while monitoring for gas leaks and conducting fire drills are important safety practices, they do not directly fall under the definition of a fire suppression system. Monitoring for gas leaks relates to preventing explosions and fires rather than extinguishing them. Fire drills are essential for preparedness and training but are not systems for fire control. Inspecting fire code compliance is crucial for ensuring that buildings meet safety standards, but this also doesn't pertain directly to the active measures taken during a fire event. The essence of a fire suppression system is its proactive and reactive measures to fight fires, making the chosen answer the best fit.
