Which of the following items can be mixed with explosives?

• A. Forklifts
• B. Pallets
• C. Barrels
• D. Storage racks

Answer: (D)

In explosive safety, the main idea is keeping materials that could create or transfer risk away from explosives and choosing items that won’t introduce ignition sources or reactive conditions when stored nearby. Storage racks fit this approach because they’re designed to organize and support loads while maintaining separation and visibility, which helps prevent contact, spills, or damage to the explosive materials. They don’t introduce ignition sources and they help you keep explosives properly partitioned from other items.

The other options pose more risk near explosives. Forklifts are powered machinery that can spark or produce heat and fumes, creating a potential initiation source. Pallets, typically made of wood, can be combustible and easily damaged, increasing fire risk and instability. Barrels may contain flammable or reactive liquids and, if damaged, can leak or react, complicating control over a storage area. Because of these hazards, they’re not considered appropriate to be mixed with explosives in the same storage space.

So, storage racks are the safer, more appropriate choice for organizing and storing near explosives without introducing additional ignition or reaction risks.
