Which of the following is not a method of release prevention?

• A. STP
• B. Inventory control
• C. Spill and overfill prevention
• D. Corrosion protection

Answer: (A)

Preventing releases means keeping materials contained and stopping spills or leaks before they escape. Inventory control helps with this by keeping precise records of what’s on site and where it is, which reduces the risk of overfilling or mis-handling during transfers that could lead to a release. Spill and overfill prevention directly reduces release potential through devices and procedures that catch spills and automatically shut off or contain a release as soon as it starts. Corrosion protection preserves the integrity of tanks, pipes, and containment systems, lowering the chance of leaks developing over time due to rust or wear. STP isn’t a standard release-prevention measure because it doesn’t address containment, spill control, or ongoing integrity of the system in the same direct way as the others.
