Wet Chemical Suppression System is used to protect modern commercial kitchen from potential threats like open flame, red hot cooking surface and heavily grease laden environment which in turn leads to oil and grease fires. The wet chemicals suppress fire by a process called saponification. Saponification is a chemical reaction that occurs when a vegetable foil or animal fat is mixed with a strong alkali. Saponification value is a measure of the amount of potassium hydroxide needed to neutralize one gram of fat or oil. The most common types of cooking media, i.e., animal fats (or lard), vegetable oils, and peanut oils, have similar saponification values. Other fats, such as cocoa, have substantially higher saponification values and therefore are more difficult to extinguish
