The
2012 Edition of NFPA 70E 130.5(C) Equipment Labeling states that the equipment label shall have
(1) At least one of the following:
a. Available incident energy and the corresponding working distance
b. Minimum arc rating of clothing
c. Required level of PPE
d. Highest Hazard/Risk Category (HRC) for the equipment
Although the 2012 edition helped clarify previous confusion by permitting posting incident energy and PPE levels, having the HRC in the same list had the potential to still create confusion. i.e. listing HRC with calculated incident energy etc.
It is proposed that the
2015 Edition of NFPA 70E will further clarify the requirements by changing the language to:
(3) At least one of the following:
[INDENT=2]a) Either the available incident energy and the corresponding working distance, or the arc flash PPE category in Table 130.7(C)(15)(b) or Table 130.7(C)(15)(d) but not both
b) Minimum arc rating of clothing
c) Site specific level of PPE[/INDENT]
Here is this week’s question: Do you think the proposed 2015 NFPA 70E language for equipment labeling helps further clarify the requirements?
