This week’s question is very subjective and is based on all kinds of variables such as lighting, eye sight etc. For an average person under normal conditions:

What is the MAXIMUM distance where the typical arc flash label details are still readable?

Less than 4 ft. (1.2 M)
Between 4 and 8 ft. (1.2 to 2.4 M)
Between 8 and 12 ft. (2.4 to 3.7 M)
Something greater than 12 ft. (3.7 M)
It depends
