A key characteristic of dry chemical extinguishers is their multipurpose use, which makes them versatile and effective in addressing a variety of fire types. These extinguishers are designed to combat fires fueled by ordinary combustibles (like wood and paper), flammable liquids (such as gasoline and oil), and energized electrical equipment. This ability to tackle multiple categories of fires is essential, especially in environments where different types of materials may be present, ensuring a comprehensive approach to fire safety and the ability to respond to unpredictable situations.

While the other options present different considerations regarding extinguisher use, they do not reflect this critical feature of dry chemical extinguishers. For example, stating that they are only for outdoor fires disregards their effectiveness in indoor environments. Likewise, claiming they operate solely on water pressure is misleading, as dry chemical extinguishers do not use water but rather a dry chemical agent pushed out by a pressurized gas. Lastly, while they may leave a residue after use, this does not detract from their primary function of extinguishing fires across various situations.
