Before a full, professional study is completed in our facility, I was wondering what type of label to use since we don't have all the information that is needed for a detailed label. We will be using tables until all of our information is gathered. None of our machinery has any types of warning or danger labels. I have found some labels that have "Danger--arc flash and shock hazard. Appropriate PPE required. Refer to NFPA 70E for minimum PPE requirements" Is this enough until we are able to get a study completed?

The NEC (which I believe is law in every state) requires it.
For Canadians, the CEC (law in every province) has a very similar requirement.

So your equipment should already have those basic warning labels.

There is hardley any of our machines that have any warning labels on them. Every now and then, you may see a high voltage sticker. How has anyone else who will have a study done, (in the future) labeled their machines until it is completed? You don't know what the PPE requirements are, unless you use the worse case senerio from the charts?

Putting a label on the equipment warning of the AF hazard does not relieve you or your company of the responsibility to perform an Arc Flash Hazard analysis. Attaching labels without the Hazard Category or Cals/cm2 serves no useful or legal value. I would recommend instructing the staff on how to use the NFPA 70E task tables until you get an analysis performed and labels attached. This is better than nothing. Also, I recommend that your staff wear HRC 2 clothing for everyday work since 90% of the equipment will be HRC 2 or less.
