märkäkemikaalisammuttimet

Märkäkemikaalisammuttimet are fire extinguishing devices that use a wet chemical solution to suppress fires involving flammable liquids, particularly those found in commercial kitchens. The solution, usually a potassium acetate or potassium citrate mixture, cools the fuel and forms a soapy film that smothers the fire, preventing re-ignition by limiting oxygen access and creating a barrier between the fuel and the flame.

These extinguishers are classified as Class K (or F) fire extinguishers in many jurisdictions, indicating their suitability for cooking oil, fat, and other hydrocarbon fuel fires. A typical unit dispenses around 12 to 14 liters of solution and is rated to extinguish small to medium-sized fires in single or dual-cook top setups. Because the chemical sinks to the bottom of the pan, it directly contacts the burning material, making it highly effective for the most common kitchen fire scenarios.

Installation and maintenance of märkäkemikaalisammuttimet follow national and local fire safety codes. Devices must be mounted within easy reach of work surfaces, and hoses should be checked for kinks or damage regularly. Empty extinguishers require recharging, and replacement intervals vary depending on usage and temperature conditions. Proper training for kitchen staff on deployment, angle of discharge, and safety distance is essential to maximize efficacy and minimize risk to personnel.

Limitations of wet chemical extinguishers include their ineffectiveness against solid fuel fires (e.g., paper, wood) and electrical fires. Improper use can lead to splashing or spreading of hot grease, potentially exacerbating an emergency. Therefore, märkäkemikaalisammuttimet are typically part of a broader fire safety strategy that includes smoke detection, fire suppression systems, and emergency evacuation plans.
