True or false: Class K fire extinguishers can be used for electrical fires.

Class K fire extinguishers are specifically designed for fires involving cooking oils and fats, typically found in commercial kitchens. These extinguishers contain agents that can effectively extinguish such flammable liquid fires without spreading them, as well as preventing re-ignition.

When it comes to electrical fires, Class K extinguishers are not intended for use. The recommended extinguishers for electrical fires are Class C or multipurpose extinguishers like Class ABC, which are safe to use on energized electrical equipment. Using a Class K extinguisher on electrical fires could be hazardous and ineffective, as the agents may conduct electricity and pose a risk to the user.

This distinction is critical for fire safety and proper handling of various types of fires in emergency situations. Hence, stating that Class K extinguishers can be used for electrical fires is false.
