What classification is assigned to the area between three feet and eight feet from any edge of outdoor equipment in bulk storage plants?

The classification assigned to the area between three feet and eight feet from any edge of outdoor equipment in bulk storage plants is based on the potential presence of flammable gases or vapors. In this context, the classification used is Class I, Division 2, which applies to locations where ignitable concentrations of flammable gases or vapors are not likely to exist under normal operating conditions but may occur in the event of equipment failure or abnormal situations.

In outdoor bulk storage plants, the space around storage tanks and equipment that is not directly in the hazardous zone but is still close enough to be affected by potential leaks or releases of flammable materials is classified this way to provide a safety buffer. The Division 2 designation indicates that while the area is generally safe, precautions must still be taken because the risk of ignition exists if a leak occurs.

This understanding allows for appropriate safety measures and equipment selection to be implemented in these environments, ensuring that the potential risks are mitigated effectively. The other classifications listed do not align with the specific nature of the environment being described, particularly Class I, Division 1, which indicates areas where flammable gases are expected to be present continuously or frequently, and Class III classifications, which pertain to locations with combustible dust hazards rather than
