Keeping chemicals in labeled containers is essential for safety in the laboratory. Proper labeling helps prevent accidents and mishandling of chemicals by clearly identifying the contents, hazards, handling instructions, and any necessary personal protective equipment (PPE) required for handling. It also facilitates easier access and inventory management, allowing lab personnel to quickly locate the substances they need while minimizing the risk of using the wrong chemical.

In contrast, storing chemicals on the floor poses a significant safety risk due to the potential for spills or tripping hazards. Mixing all chemicals together can lead to dangerous reactions, while storing chemicals in random locations can result in confusion and increase the likelihood of improper handling or accidents. Therefore, using labeled containers is a best practice that enhances both safety and efficiency in the lab environment.
