After countless emails and informal meetings about it, I was told "we looked into it and we decided that we are not going to spend the money that it will take to do an arc-flash analysis. Instead, we will use the task tables of NFPA 70E."
My jaw about hit the floor on that one.
Using the tables is an acceptable option, however in order to use the tables your plant needs to do some analysis to see if the tables can be used at your facility. The tables are based on some limiting factors, listed in the notes of the tables. Your plant needs to ensure you do not exceed the max available fault current and clearing times of the OCPD's listed for each type of equipment.
In my experiance most large industrial facilities to not meet the limits of the notes on part of thier system.
I came across the same thing with a client once, they were just going to use the tables and wanted me to train thier staff on proper use, when I questioned the table limits they said I was assuming they did not meet them, I said no you are assuming you do. So I offered to do the calcs to find out if the tables apply for free, on my own time, they delcined the offer and said "If something were to happen, we have a burn center on site" (This was a hospital), my jaw hit the floor. Then they said for me to just tell thier staff in the training the tables were OK to use, I told them to find someone else to lie for them and left.
