In Denver, what is the primary method for extinguishing a grease fire?

The primary method for extinguishing a grease fire involves using a Class K fire extinguisher. This type of extinguisher is specifically designed to combat fires involving cooking oils and fats, which are common in kitchen environments. Class K extinguishers contain wet chemical agents that effectively cool and smother the flames, preventing re-ignition.

In comparison, using water to cool the flames is ineffective and dangerous since water can cause the burning grease to splatter and spread the fire further. Pouring flour over the fire is a common myth and can also be hazardous as it may not effectively suppress the flames and could potentially ignite. Covering the fire with a metal lid can help isolate the fire from the oxygen supply, but if not done properly or if the lid is not the right size, this method may not be as effective as using a Class K extinguisher specifically designed for such fires. Therefore, employing a Class K fire extinguisher is the most reliable and safest approach to extinguish a grease fire in Denver.
