Final Day our #FirePreventionWeek Q&A! Q: What is the discharge distance of a Class D extinguisher? How effective are they? A: Class D fire extinguishers, which are used for combustible metals and alloys (e.g., aluminum, magnesium, titanium, potassium), have a very short discharge distance. Compared to Class A and Class ABC extinguishers that have a 15-20 feet discharge distance (at a minimum), Class D extinguishers have a discharge distance of less than 5 feet, typically closer to ~2 feet.
