A loaded stream charge refers specifically to a type of extinguishing agent used in certain fire extinguishers, particularly those that utilize a water-based solution enhanced with additives to improve its effectiveness. This type of agent is designed to be discharged as a stream of water, which can penetrate and cool the burning material effectively. It is important in fighting Class A fires, which involve ordinary combustibles like wood, paper, and cloth.

The water-based solution typically contains additives that help to increase its fire-extinguishing properties, making it more efficient compared to plain water. This means that while the primary component is still water, the "loaded" aspect refers to the additional chemicals that augment the extinguisher's performance and expand its usability beyond what regular water would provide.

This understanding emphasizes the role of water-based solutions in firefighting, while other types of agents—like powdered chemical, aerosol-based, and foam agents—serve different purposes and are tailored to combat specific classes of fires. For instance, powdered chemical agents are commonly used for flammable liquids and gases, while foam agents are effective for liquid fires, demonstrating the diversity in fire suppression methods based on the combustion material involved.
