Which option correctly identifies items to avoid when handling ammunition?

• A. Water and oil
• B. Dirt and rust
• C. Solvents and lubricants
• D. Heat and moisture

Answer: (C)

Ammunition must be kept free from chemical contaminants that can alter its internal components. Solvents and lubricants are especially problematic because they can seep into the cartridge, weakening the powder or primer and changing ignition characteristics, or leave a film that promotes corrosion or unreliable firing. Even small amounts can degrade performance, so you should avoid any contact with solvents or lubricants when handling ammo. While environmental factors like water, dirt, rust, heat, and moisture are also hazards, solvents and lubricants pose a direct chemical threat to the ammunition itself, making them the best choice to avoid.
