Liquids must be stored with secondary containment bins.

• A. Not applicable
• B. Not sure
• C. False
• D. True

Answer: (D)

The main idea is safety and spill control. Liquids can leak or spill from containers at any time, so having secondary containment provides a catch basin to hold any escaped liquid. This protects people, prevents contamination of surfaces and drains, and helps meet safety regulations that require containment for liquids, especially hazardous ones. The secondary containment bin—like a spill tray or pallet—is designed to hold the volume of the containers it surrounds and is made of chemical-resistant material appropriate for the stored liquids. Because of these protections and compliance benefits, storing liquids with secondary containment is best practice, so the statement is true.
