What should never be stored in containers without proper markings?

The practice of marking containers is critical for safety and compliance, particularly when it comes to hazardous substances. These substances can pose significant risks to health, safety, and the environment if not handled correctly. Proper labeling ensures that individuals can quickly identify the contents of a container, understand the associated risks, and take appropriate precautionary measures.

For example, a container filled with a hazardous chemical may require specific handling, storage, and disposal procedures to prevent accidents or spills. Unmarked containers could lead to misunderstandings, improper use, or accidental exposure, resulting in potentially severe consequences.

In contrast, while food items, personal items, and cleaning supplies also benefit from proper labeling for various reasons, the critical nature of safety and regulatory compliance surrounding hazardous substances makes them a particular focal point. Ensuring that these materials are clearly marked aligns with safety protocols and helps maintain a safe working and living environment.
