If you are unsure about using the Class K extinguisher, what is the recommended action?

• A. Evacuate people if needed and then use the extinguisher only if you are trained and it is safe
• B. Immediately attempt to extinguish using water
• C. Ignore and continue working
• D. Call the fire department and wait outside

Answer: (A)

The situation emphasizes safety first. For a cooking oil fire, if you’re unsure how to operate a Class K extinguisher, your best course is to evacuate people if needed and then only intervene with the extinguisher if you have proper training and it can be done safely. This matters because Class K agents are designed specifically for oil fires and improper use can spread flames or cause splattering and burns. Water should never be used on oil fires, as it can cause a dangerous reaction. If you’re not trained, prioritize getting people out and calling for professional help rather than attempting to fight the fire.
