Which of the following is a characteristic of the Mono Ammonium Phosphate Extinguisher?

The characteristic of Mono Ammonium Phosphate Extinguishers is that they are effective for paint thinner fires, which typically involve Class B fires. Mono Ammonium Phosphate is a versatile dry chemical that can extinguish fires involving flammable liquids, such as those associated with paint thinners. These extinguishers can disrupt the chemical reaction of the fire and are commonly used for both Class A (ordinary combustibles) and Class B fires due to their ability to suppress the flames effectively.

While other types of extinguishers are designed specifically for metal fires, such as Class D extinguishers, Mono Ammonium Phosphate is not suitable for that purpose. The discharge method is also not in line with a fine mist; these extinguishers typically discharge in a powder form rather than as a mist. Additionally, when handled properly, Mono Ammonium Phosphate is not considered corrosive, making it safe for a variety of applications when aiming to suppress fires.
