Where should highly reactive chemicals or those in containers larger than one gallon be stored?

• A. In a separate cabinet
• B. In a general storage cabinet
• C. On an open shelf
• D. In a location isolated from other chemicals

Answer: (D)

Store highly reactive chemicals and those in large containers in a location isolated from other chemicals. This separation minimizes the risk of dangerous reactions if incompatibles touch or mix, and reduces the potential impact of spills or leaks from large-volume containers. Isolation also helps prevent cross-contamination and exposure by keeping volatile or reactive substances away from everyday products and handling areas. In practice, this means a dedicated, clearly labeled area (often with ventilation and secondary containment) that is physically separated from other chemicals. The other storage options do not guarantee this level of separation, so they don’t provide the same safety protection.
