Liquid chemicals are stored in drums, totes, or intermediate bulk containers (IBCs) in a warehouse. These containers are made of plastic or metal and are designed to store hazardous materials safely. The containers are typically stored on pallets, and the warehouse should be equipped with fire suppression systems, spill containment systems, and other safety measures to minimize the risk of chemical spills or fires. Additionally, the storage area should be properly labeled and separated from other areas to ensure that chemicals are stored separately from other materials. Access to the storage area should be limited to authorized personnel only.
