I was just reading an article by Jim Pillips in Electrical Contractor magazine about understanding working distances. The introduction states:

"The term 'working distance' appears 20 times in the 2012 Edition of NFPA 70E, the Standard for Electrical Safety in the Workplace. It appears 12 more times in the annexes. The working distance is an important component of the arc flash hazard analysis and is frequently listed on arc flash warning labels and in the arc flash report."

The article then discusses five common working distance mistakes:

1- Working too close
2- Parts of the body closer than the working distance
3- Incorrect input data
4- Unexpected energized parts upfront
5- Rear accessible equipment
