sammutusväli

Sammutusväli, translated as "extinguishing gap" or "fire break" in English, is a concept primarily used in the context of wildfire management and urban planning in Finland and other Nordic countries. It refers to a cleared or prepared area of land designed to prevent the spread of fire. These areas are intentionally kept free of flammable materials such as trees, shrubs, and dry grass.

The primary purpose of a sammutusväli is to act as a barrier against the uncontrolled advance of a wildfire. By removing fuel, it creates a zone where fire cannot easily propagate. This can be crucial in protecting populated areas, valuable infrastructure, or sensitive ecosystems from destruction. In urban settings, sammutusvälit are often established between different zones of development or between built-up areas and surrounding forests or open land.

The width and maintenance of a sammutusväli depend on various factors, including the type of vegetation, topography, prevailing wind conditions, and the perceived risk of fire. Regular maintenance is essential to ensure its effectiveness, which may involve clearing vegetation, controlled burning, or creating fire-resistant landscaping. The concept is a proactive measure, aiming to contain fires before they become unmanageable, thus reducing potential damage and enhancing safety.
