Between what distances is the area classified as Class I, Division 2 near outdoor equipment that can have flammable vapor-air mixtures?

The area classified as Class I, Division 2 near outdoor equipment that can produce flammable vapor-air mixtures is defined by specific distance criteria to ensure safety. The correct answer highlights that the classification applies within a range from 3 feet to 8 feet. This distance range is important because it recognizes that, while the likelihood of flammable mixtures being present is less than in Division 1 areas, there is still a potential for such conditions to occur.

This classification is vital for safety as it helps in determining the right protective measures and equipment specifications necessary to prevent ignition sources from causing fires or explosions in the vicinity of where flammable vapors may collect. It is based on the potential dispersion and accumulation of flammable vapors from equipment and the characteristics of the environment around it.

In contrast, other options fall outside the established distances recognized by safety standards for hazardous locations, thereby not accurately reflecting the boundaries for Class I, Division 2.
