What type of fires are Class A extinguishers specifically designed to combat?

Class A extinguishers are specifically designed to combat fires that involve ordinary combustibles, which include materials such as wood, paper, cloth, and some types of plastics. These fires are characterized by their solid fuel sources that burn easily and are common in residential and commercial settings. The extinguishing agents typically used in Class A extinguishers, such as water or foam, are effective in cooling these materials and preventing re-ignition. Understanding the appropriate use of Class A extinguishers is crucial for effective fire safety and firefighting strategies, as using the wrong type of extinguisher can be ineffective and potentially hazardous during a fire incident.
