Which fire extinguishing agent would NOT be appropriate for a Type A fire?

A halogenated agent would not be appropriate for a Type A fire because these agents are specifically designed for use on flammable liquid fires and electrical fires, not on ordinary combustible materials such as wood, paper, and cloth, which are classified under Type A fires. Type A fires occur when materials that produce ash burn, and the recommended extinguishing agents for these types of fires typically include water or foam, which are effective in cooling and extinguishing the flames due to the nature of the materials involved.

In contrast, multipurpose dry chemical extinguishers, water types, and wet chemical extinguishers can effectively address Type A fires. Multipurpose dry chemicals can work on multiple fire types, including Type A, while water is ideal for cooling down burning materials. Wet chemical extinguishers are specifically intended for use on cooking oils and fats but can also be effective on certain Type A fires. Therefore, halogenated agents do not serve the purpose of extinguishing Type A fires effectively.
