How should fuel tanks be secured against tampering?

Fuel tanks should be secured against tampering primarily by utilizing locking mechanisms and barriers. This method ensures that unauthorized individuals cannot easily gain access to the tanks, thereby minimizing the risk of fuel theft, vandalism, or accidental spills that could result from tampering. Locking mechanisms, such as padlocks or combination locks, effectively restrict access while barriers, like fences or locked enclosures, provide a physical deterrent against intruders.

Employing these security measures is essential in protecting both the tanks and the surrounding environment. Secure fuel tanks help in maintaining compliance with regulations and safety standards that govern fuel storage practices. This approach not only safeguards the fuel supply but also reduces potential liabilities associated with hazardous materials.

The other options presented—leaving tanks unlocked, relying solely on surveillance cameras, or no security measures—do not provide adequate protection and could lead to serious consequences, demonstrating why securing fuel tanks appropriately is critical.
