The correct method to unload tanks upon arrival at the job site is to lift them off with a cable attached to the tank lifting lugs. This approach is essential for ensuring safe handling and preventing damage to the tank during the unloading process. Using the designated lifting lugs provides a secure and stable point for attaching lifting equipment, which minimizes the risk of accidents or spills.

Additionally, properly using lifting equipment, such as a crane or forklift, that is rated for the weight of the tank ensures that the tank can be unloaded efficiently and safely without risking injury to personnel or damage to the tank or surrounding property. This method adheres to industry best practices and safety regulations, reflecting the importance of proper lifting techniques in handling underground storage tanks.

In contrast, the other methods would not provide the same level of safety or stability. Lowering a tank directly onto the ground risks damage to the tank and may lead to spills or unsafe situations. Using a crane to drop the tanks from a height or wrapping a chain around the tank for support can cause serious injuries or damage, as they do not ensure the tank is properly supported during the unloading process. Thus, lifting tanks with a cable attached to the lifting lugs is the safest and most effective unloading method.
