What is the minimum distance required between a flammable storage locker and an explosive location?

• A. 50 feet
• B. 25 feet
• C. 100 feet
• D. 10 feet

Answer: (A)

The important idea here is providing a safe separation between where flammable liquids are stored and where explosives are kept. If a fire starts in a flammable storage locker, heat, sparks, or flames could reach nearby explosives and trigger an explosion or send fragments and blast effects toward the storage area. A defined minimum distance reduces the chances of heat transfer, flame exposure, and debris affecting the explosive location. Fifty feet is used as a conservative buffer that typically meets safety requirements for limiting heat exposure and blast impact between these two kinds of hazards. Distances like twenty-five feet or ten feet would be too close to reliably prevent ignition transfer or fragment/overpressure effects. A hundred feet would exceed the minimum and, while safer, is not the required minimum in standard practice.
