Portable magazines designed to hold less than 50 kg must be resistant to which factors?

• A. Elements and pilferage
• B. Fire and water
• C. Only weather
• D. Only pilferage

Answer: (A)

Protecting stored explosives from both environmental exposure and unauthorized access is the key idea here. Portable magazines holding less than 50 kg must be built to withstand the elements—rain, moisture, temperature changes, and other weather-related conditions that could degrade contents or damage the container—and also to deter pilferage, meaning they need to be secure against theft or tampering with sturdy locks and tamper-resistant design. The other options miss one of these essential protections: focusing only on weather neglects the security aspect, and emphasizing only pilferage or only fire/water doesn’t cover both risks. So the best choice is resisting both the elements and pilferage.
