Which two types of munitions fire are mainly recognized?

The correct answer highlights the two main types of munitions fire recognized in fire protection and firefighting scenarios. Class A munitions are typically associated with conventional explosives and ordnance that can ignite or create a fire involving common combustible materials. This type of fire is generally approached using standard firefighting techniques.

Class D munitions, on the other hand, involve combustible metals, which require specialized techniques for extinguishing fires, as they react to water and conventional extinguishing agents in hazardous ways. Such fires are often managed with dry powder agents specifically designed for metal fires and require unique firefighting protocols.

Understanding these two classifications—Class A and Class D—enables first responders to effectively strategize their firefighting measures, ensuring both safety and effectiveness when handling munitions-related incidents.
