What type of fire protection measure significantly reduces fire damage?

Active systems such as sprinklers play a crucial role in significantly reducing fire damage. These systems are designed to detect and respond to a fire automatically, often before it has the chance to spread. When a fire is detected, the sprinklers release water directly to the affected area, effectively dousing the flames and minimizing heat and smoke production. This early intervention is key in containing fires, which can prevent extensive damage to property and save lives.

In contrast, passive fire protection measures, while important, are focused on preventing the spread of fire and smoke through fire-resistant construction materials and barriers. Regular fire drills enhance preparedness and response but do not directly suppress fires. Manual fire extinguishers provide a means for individuals to fight small fires before they escalate but rely on the presence and action of people to be effective. Active systems like sprinklers stand out as the most effective in reducing damage by actively combating the fire as it occurs.
