A fire extinguisher system specifically addresses fire-related hazards, as it is designed to suppress or extinguish flames to prevent further damage and protect life and property. Fire extinguishers operate by discharging specific agents that can cool the flames, smother them, or interrupt the chemical reaction that fuels the fire. This critical functionality is only relevant when dealing with fires, making "fire-related hazards" the most appropriate answer.

While chemical spills, biological risks, and structural failures are significant risks in various contexts, they are not situations that fire extinguishers directly mitigate. Chemical spills may require containment and cleanup measures, biological risks often necessitate specialized protective equipment or procedures, and structural failures involve addressing integrity issues in a building. Thus, understanding the primary purpose of fire extinguishers clarifies why fire-related hazards are the correct focus for these systems.
