How should dry chemicals be arranged in storage?

Storing dry chemicals on shelves above liquid chemicals is the preferred practice for several important safety and practicality reasons. When dry chemicals are placed above liquid chemicals, it minimizes the risk of contamination. In the event of a spill or leak from the liquid containers, having dry chemicals stored above helps prevent those chemicals from coming into contact with liquids, which could potentially create hazardous reactions or make the dry chemicals unusable due to contamination.

Additionally, having dry chemicals above liquid chemicals allows for easier access and organizational efficiency, as it is generally safer to reach for lightweight dry materials stored at a higher level rather than having them at lower levels where liquid chemicals might be spilled.

Maintaining a separate area for storage of dry and liquid chemicals, while safe, is not always practical in all settings, and some facilities may not have that kind of space available. It is also important to avoid storing dry chemicals with volatile chemicals due to the potential for dangerous reactions or increased fire hazards. Thus, arranging dry chemicals on shelves above liquid chemicals adheres to best practices in terms of safety and organization.
