What is the maximum travel distance to reach a B rated extinguisher?

• A. 20 Feet
• B. 75 Feet
• C. 100 Feet
• D. 50 Feet

Answer: (D)

The main idea is that extinguishers must be close enough to reachable from any point in the area so you can start a safe, quick initial attack before a fire grows. For fires involving flammable liquids (class B), the standard maximum travel distance to reach an extinguisher is 50 feet. This tighter spacing reflects how quickly a flammable liquid fire can spread and the need for rapid access to a suitable extinguisher.

In practice, that means you’d place B-rated extinguishers so no area is more than about 50 feet from one of these extinguishers, helping occupants respond quickly and increasing the chance of keeping a small fire from becoming large. Other classes have different spacing requirements (for example, spaces with ordinary combustibles often use larger distances), but for B-rated extinguishers the 50-foot rule is the guideline.
