In a motor fuel dispensing facility, up to what height above floor level is an area considered Class I, Division 2?

• A. 2 feet
• B. 3 feet
• C. 4 feet
• D. 5 feet

Answer: (B)

In a motor fuel dispensing facility, the classification of areas is critical for ensuring safe operation and compliance with safety regulations. The area considered Class I, Division 2 extends up to 3 feet above the floor level. This classification is based on the presence of flammable gases or vapors that could be released during regular operations, such as fuel dispensing. Class I refers to locations where flammable gases or vapors may be present in the air in sufficient quantities to produce explosive or ignitable mixtures. Division 2 covers areas where such gases or vapors are not normally present in the air in sufficient quantities but may accidentally be present under abnormal conditions. Therefore, the 3-foot height is significant because it represents the boundary in which the possibility of a combustible atmosphere exists during typical operations, making it necessary to implement specific safety measures and equipment designed to prevent ignition. This includes using explosion-proof equipment and adhering to safety standards in these designated areas.
