What should you do with water-reactive chemicals?

For handling water-reactive chemicals, it is crucial to keep them away from plumbing. Water-reactive substances can react violently or release hazardous gases when they come into contact with water, including moisture from plumbing systems. Therefore, storing these chemicals away from any potential water source minimizes the risk of accidental contact and subsequent reactions that could lead to dangerous situations, including explosions or the release of toxic fumes.

In terms of the other options, storing water-reactive chemicals with acids could lead to dangerous reactions if they interact. Placing them in unlabeled containers poses risks of misuse or accidental exposure since labeling is critical for safety and identification in a laboratory environment. Similarly, storing these chemicals on high shelves could increase the risk of spills or falls, especially if they are heavy, making them difficult to manage safely. Keeping them at a lower level, away from plumbing and potential sources of moisture, is the safest approach.
