Answer :
Final answer:
A Class K fire, primarily caused by cooking oils and fats, should be extinguished using a wet chemical. This extinguishing agent reacts with the oil or fat to create a thick, soapy substance that cools the fire and prevents it from re-igniting. Other substances, such as carbon tetrachloride have been phased out due to their adverse health effects.
Explanation:
The correct extinguishing agent for a Class K fire, which often involves cooking mediums like oils and fats, is wet chemical. Unlike water, carbon dioxide, or dry chemicals, wet chemical fire extinguishers are designed specifically for kitchen fires fueled by cooking oils and fats. These use a solution that reacts with the oil or fat to create a thick, soapy substance, cooling the fire and preventing re-ignition.
While substances like carbon tetrachloride were once used in fire extinguishers due to their ability to inhibit combustion, they have been phased out because of adverse health effects and environmental problems, such as the formation of phosgene, a toxic gas.
In other Class K fire cases, one might consider using a specialized foam, but it requires professional application – in general, the safe and suggested method to extinguish Class K fires is with wet chemical extinguishers.
