The area classified as a Class I, Division 2 location from aircraft fuel tanks extends how far horizontally?

In hazardous locations, specifically regarding Class I, Division 2 areas, the horizontal extent from a potential source of flammable vapors is an important safety consideration. The correct choice indicates that the Class I, Division 2 area, which is associated with the presence of flammable gases or vapors, extends 5 feet horizontally from aircraft fuel tanks.

This classification is based on the understanding that in a Division 2 area, the hazardous materials are not normally present but may be released due to a malfunction or an upset condition. Therefore, creating a safe zone around the source is crucial to minimize any risks associated with these materials. The 5-foot distance allows for potential vapors to disperse in a controlled environment, providing an adequate buffer to prevent ignition sources from entering the area where flammable substances could accumulate.

Understanding the implications and safety distances for Class I, Division 2 classifications is essential for compliance with safety standards and for ensuring the safety of personnel working near such hazardous locations.
