How should chemicals be stored to ensure safety?

Storing chemicals in a locked cabinet is the safest practice because it helps prevent unauthorized access, particularly from children or untrained individuals who may not be aware of the hazards associated with certain substances. This method not only limits accidental exposure but also mitigates the risk of intentional misuse.

Additionally, a locked cabinet allows for better organization and separation of hazardous materials from other items in the environment, ensuring a controlled area that minimizes cross-contamination and accidents. Considerations for chemical storage include ensuring adequate ventilation and observing compatibility between different chemicals, which is more easily managed in a secure environment.

While storing chemicals on open shelves may seem convenient, it exposes them to accidental spills or contamination. Keeping them near food items compromises food safety and increases the risk of chemical ingestion. Using glass containers can be appropriate depending on the type of chemical and its reactivity, but it doesn't address the critical need for secure storage from unauthorized access. Collectively, these aspects reinforce why storing chemicals in a locked cabinet is essential for safety.
