The limited approach boundary is 1', the restricted approach boundary is "avoid contact".Do DC batteries above 56V require shock protection PPE?
You are correct, I looked at the wrong line on the table.NFPA 70E-2015, Table 130.4(D)(b) says that for <100VDC, the Limited Approach Boundary and Restricted Approach Boundary are "not specified." Nonetheless, OSHA says employees exposed to live unguarded parts of 50V or more must wear appropriate PPE. So, shock protection, yes.
And, according to NFPA 70E-2015, Table 130.7(C)(15)(b) (I wish their numbering scheme was consistent), the Arc Flash Boundary could be 1, 2 or 3, depending upon the short-circuit current. So, arc-rated PPE, maybe.
