What is required when bottles and containers are not in use?

When bottles and containers are not in use, it is important for them to remain closed to prevent contamination, maintain stability, and ensure safety. Keeping containers closed minimizes the risk of spills and exposure to external contaminants that could compromise the contents. This practice is especially crucial in environments handling sensitive substances, such as chemicals or pharmaceuticals, where exposure can affect efficacy or safety.

Maintaining containers in a closed position also helps to preserve the integrity of their contents, preventing evaporation or degradation that could occur if they were left open. Ensuring that all containers are closed when not in use is a fundamental standard in various regulatory frameworks to promote safe handling and storage practices.

Controlling temperature or placing items in sunlight would not be appropriate for all types of substances, and labeling requirements may vary based on specific regulations but are not the primary focus when ensuring safety during periods of non-use.
