Which item is typically included in a secondary containment system for chemical storage?

• A. A raised tray to catch leaks
• B. A binder full of MSDS
• C. A spill kit
• D. A warning sign

Answer: (A)

Secondary containment is about catching leaks from primary chemical containers to prevent spills from reaching the floor or environment. A raised tray or containment tray under the containers provides a physical basin that collects any leaks, drips, or small spills, keeping them in a defined area and making cleanup and regulatory adherence easier. The other items serve related safety roles but don’t form the containment itself: an MSDS binder stores hazard information, a spill kit is for cleaning up spills after they happen, and a warning sign communicates hazards rather than containing liquids.
