Which statement about spill buckets is incorrect?

1. Spill containers must allow drainage of the collected spill into the primary container.

2. The exterior wall of spill containers shall be protected from galvanic corrosion.

3. Spill containers shall have a minimum capacity of five gallons (19 liters).

4. Spill containers must be installed on all fill and phase I vapor recovery lines.

The correct answer is: Spill containers must be installed on all fill and phase I vapor recovery lines.

The statement about spill containers that is inaccurate pertains to the installation requirements for spill containers. While spill containers are generally required at certain points in a fueling system, the specific requirement for installation on all fill and phase I vapor recovery lines is not universally applicable. Spill containers are primarily intended to capture and contain spills during the filling process and are generally required on the fill lines. However, the requirement for them to be installed on all phase I vapor recovery lines is not standard practice. Phase I vapor recovery systems are designed to capture gasoline vapors during the transfer of fuel from a tanker truck to the storage tank, and they do not typically require spill containers because they manage vapor release rather than liquid spills. The other statements correctly reflect important aspects of spill container requirements. They must allow drainage to the primary container to ensure proper spill management, protect the exterior from galvanic corrosion to prevent degradation over time, and have a minimum capacity of five gallons to adequately contain potential spills.
