The identification of fire types is crucial for effective firefighting and safety measures. In this context, the correct association is as follows: A computer fire is classified as type C. Fires involving electrical equipment, such as computers, require the use of certain types of extinguishing agents that can safely put out the flame without conducting electricity or causing further hazards. A trash fire is identified as type A. This type involves ordinary combustibles like wood, paper, and textiles, which are typically found in trash and can be extinguished using water or other standard methods. A magnesium fire is known as type D. This fire class specifically pertains to combustible metals. Magnesium burns at a high temperature and reacts violently with water, necessitating specialized extinguishing agents for containment. Finally, a gasoline fire is classified as type B. This type involves flammable liquids, such as gasoline, that require foam or dry chemical fire extinguishers for effective suppression, as water will not extinguish it and can instead spread the fire. Understanding these classifications can significantly impact the response to fire incidents and ensure that proper firefighting methods and resources are deployed. Each classification dictates the appropriate response and type of firefighting agent to be used in case of a fire incident.
