Why is proper storage of chemicals critical in the lab?

Proper storage of chemicals is critical in the lab primarily to prevent reactions between incompatible substances and maintain safety. Chemicals can be highly reactive, and storing them improperly can lead to dangerous situations, such as explosions, fires, or the release of toxic gases. For instance, certain acids should never be stored next to bases, as this could lead to violent reactions. Additionally, ensuring that chemicals are stored in suitable containers and conditions (such as appropriate temperature and humidity) helps to preserve their integrity and prevents degradation or unintended reactions over time.

While using up old stocks of chemicals, making room for new supplies, or keeping chemicals within easy reach may be practical considerations, they do not directly address the critical safety concerns associated with chemical reactions and interactions. Proper storage focuses on minimizing risks and maintaining a safe laboratory environment, which is paramount for the well-being of everyone in the facility.
