Rule 410-1 with Footnotes - Marked for Interpretation

Table 410-1 of the 2012 NESC provides values for "the effective rating of clothing or a clothing system to be worn by employees on or near energized lines, parts, or equipment."  (See Rule 410.A.3.a.)  The Agency has determined that many of the values listed in Table 410-1 are accetpable for compliance with 29 CFR 1910.269(1)(8)(ii) because the notes to the table make clear that those values are based either on testing data or on calculations performed using methods described in IEEE Std 1584-2002 (IEEE Guide for Performing Arc Flash Hazard Calculations).
