What are the two main types of fire extinguishers?

The two main types of fire extinguishers are classified as portable and fixed extinguishing systems. Portable extinguishers are designed for individual use and can be easily transported to different locations to combat fires. They are typically suited for small fires or initial fire response. On the other hand, fixed extinguishing systems are installed as permanent fixtures in buildings or specific areas and are activated automatically or manually to suppress fires without the need for operator intervention.

While some of the other options may describe various classes or types of extinguishing agents, they do not encapsulate the overall categories of extinguishing systems. For instance, aerosol and liquid extinguishers may refer to the state of the extinguishing agent, but they are not recognized as primary categories of fire extinguishers. Similarly, water and foam extinguishers represent specific types of portable extinguishing solutions rather than differing system classifications. Chemical and biological extinguishers do not accurately depict standard fire protection categorizations either. Understanding the distinction between portable and fixed extinguishing systems provides a clearer framework for fire safety and response procedures.
