All piles shall have at least how many centimeters distance from the walls of the magazine?

• A. 15 centimeters
• B. 10 centimeters
• C. 20 centimeters
• D. 5 centimeters

Answer: (A)

The principle at work is keeping a safe clearance between the explosive piles and the magazine walls to allow air circulation, prevent direct contact with walls, and give room for safe handling and inspection. Fifteen centimeters is the chosen minimum because it provides a practical air gap that helps dissipate heat, reduces the risk of moisture buildup against the walls, and gives space for workers and equipment to access and check the piles without crowding them. A smaller gap would be inadequate for ventilation and safe access, while a larger gap would waste storage space without adding meaningful safety benefits.
