Sammutuskaasujärjestelmän

Sammutuskaasujärjestelmän, which translates to "gas extinguishing system" in English, is a fire suppression system that uses a clean gaseous agent to extinguish fires. These systems are commonly employed in areas where water or other traditional extinguishing agents could cause significant damage to sensitive equipment or materials. Examples include data centers, server rooms, telecommunication facilities, museums, archives, and industrial control rooms.

The operation of a Sammutuskaasujärjestelmän typically involves a detection system that identifies a fire, often through smoke detectors or heat sensors. Once a fire is confirmed, the system automatically or manually releases a specific volume of extinguishing gas into the protected area. The gas works by either reducing the oxygen concentration below the level required for combustion or by absorbing heat from the fire, thereby interrupting the combustion process.

Common extinguishing gases used in these systems include inert gases like Inergen (a mixture of nitrogen, argon, and carbon dioxide) or Argonite (a mixture of argon and nitrogen), and halocarbon agents such as FM-200 or Novec 1230. Each gas has different properties regarding environmental impact, toxicity, and effectiveness. Inert gases are environmentally friendly as they have no ozone depletion potential or global warming potential. Halocarbon agents are effective at lower concentrations but may have environmental concerns.

The design and installation of a Sammutuskaasujärjestelmän require careful consideration of room volume, potential fire hazards, and the specific characteristics of the chosen extinguishing agent to ensure effective fire suppression and occupant safety. These systems are a critical component of fire protection strategies in environments where traditional methods are unsuitable.
