At what distance from the explosive magazine should grass, brush, and combustibles be kept cleared?

• A. 25 feet
• B. 50 feet
• C. 75 inches
• D. 100 feet

Answer: (B)

The principle here is to create a safety buffer around the explosive magazine so that heat, sparks, or flames from blasting activities won’t ignite nearby vegetation. Keeping grass, brush, and other combustibles cleared a distance away reduces the risk of a fire reaching the magazine and gives firefighters space to respond if needed. The standard distance for this protection is 50 feet, which provides an effective balance between safety and practical site operations. The other options aren’t the usual clearance: 25 feet is too close to reduce fire risk, 100 feet is more conservative than required for this rule, and 75 inches uses an odd unit distance that isn’t the standard measure.
