A Gilbarco Vapor VAC/OPW Vapor Saver system is considered to have a vapor recovery equipment defect if the vapor escape guard is missing or damaged on at least what percentage of the circumference?

• A. 25
• B. 50
• C. 75
• D. 100

Answer: (C)

The correct answer is based on industry standards that define a significant defect in vapor recovery systems, specifically focusing on the effectiveness of the vapor escape guard. A vapor escape guard is crucial for preventing vapors from escaping into the atmosphere during fuel dispensing. When it is missing or damaged, it compromises the entire vapor recovery system’s efficiency and can lead to regulatory non-compliance and environmental hazards.

Having a vapor escape guard missing or damaged on at least 75% of the circumference indicates a serious defect that can significantly increase vapor emissions. The vital threshold is set at this percentage because it represents a critical point where the system can no longer function effectively, thereby failing to meet safety and environmental control standards. This ensures that even if a small portion of the circumference is intact, the overall integrity of the vapor recovery system is jeopardized if a large portion is compromised.
