During portable toilet inspections, which feature is recommended underneath to prevent leakage?

• A. A ventilation shaft
• B. A secondary containment underneath
• C. A decorative canopy
• D. A built-in heater

Answer: (B)

The main idea is to prevent leaks from the portable toilet by having a secondary containment underneath. This means the unit sits on a catch basin or lined tray that can hold any liquid if the main tank leaks or a hose spills. It protects soil and groundwater from contamination and makes cleanup easier, which is especially important on job sites or events where spills could spread quickly. A secondary containment provides a safety margin beyond the vessel itself, so even if there’s a minor failure, the liquid stays contained. The other features don’t address leakage: a ventilation shaft helps with odors, a decorative canopy is cosmetic, and a built-in heater is for cold-weather comfort.
