What is the coverage area of an AFFF extinguisher?

The coverage area of an AFFF (Aqueous Film Forming Foam) extinguisher is typically around 40 square feet. This type of extinguisher is specifically designed for fighting flammable liquid fires, such as those involving gasoline, oil, and other hydrocarbons.

AFFF works by creating a blanket of foam that smothers the fire and prevents oxygen from fueling the flames, while also cooling the surrounding area. Understanding the effective coverage area is crucial for ensuring that the extinguisher can adequately suppress a fire before it spreads. Choosing the correct coverage area reinforces the importance of fire safety and proper equipment usage in emergency situations.
