Fire Extinguishers Wet Chemical are specially designed to fight Class F fires involving cooking oils and fats, making them essential for kitchens, restaurants, hotels, and food processing areas. They work by spraying a fine mist that cools the flames and forms a soapy layer on the oil’s surface, preventing re-ignition. Wet Chemical extinguishers can also tackle Class A fires (solid combustibles), offering versatile protection. Key features include high effectiveness on kitchen fires, residue-minimizing agent, stainless steel body, and easy refilling for long-term safety.
