PPE TABLE EXTRACTED FROM 2018 EDITION OF NFPA 70E STANDARD FOR ELECTRICAL SAFETY IN THE WORKPLACE
NFPA 70E – 2018
NOTE: “Table 130.5(G) identifies the arc-rated clothing and other PPE requirements of Article 130 and shall be permitted to be used with the incident energy analysis method of selecting arc flash PPE.”
CAUTION: It is advantageous to specify or select arc-rated equipment that will be exposed to less than its rating during a fault. The testing of arc-rated clothing is based on 50% probability of success. Exceeding the minimum requirement can substantially increase the probability of success.
Table 130.5(G) Selection of Arc-Rated Clothing and Other PPE When the Incident Energy Analysis Method Is Used
Incident energy exposures equal to 1.2 cal/cm2 up to 12 cal/cm2
Arc-rated clothing with an arc rating equal to or greater than the estimated incident energya
Long-sleeve shirt and pants or coverall or arc flash suit (SR)
Arc-rated face shield and arc-rated balaclava or arc flash suit hood (SR)b
Arc-rated outerwear (e.g., jacket, parka, rainwear, hard hat liner) (AN)
Heavy-duty leather gloves, arc-rated gloves, or rubber insulating gloves with leather protectors (SR)c
Hard hat
Safety glasses or safety goggles (SR)
Hearing protection
Leather footwear
Incident energy exposures greater than 12 cal/cm2
Arc-rated clothing with an arc rating equal to or greater than the estimated incident energya
Long-sleeve shirt and pants or coverall or arc flash suit (SR)
Arc-rated arc flash suit hood
Arc-rated outerwear (e.g., jacket, parka, rainwear, hard hat liner) (AN)
Arc-rated gloves or rubber insulating gloves with leather protectors (SR)c
Hard hat
Safety glasses or safety goggles (SR)
Hearing protection
Leather footwear
Incident energy exposures equal to or greater than 40 cal/cm2
Energized work shall not be performed
PPE ratings not applicable
SR: Selection of one in group is required.
AN: As needed.
Notes:
a Arc ratings can be for a single layer, such as an arc-rated shirt and pants or a coverall, or for an arc flash suit or a multi-layer system if tested as a combination consisting of an arc-rated shirt and pants, coverall, and arc flash suit.
b Face shields with a wrap-around guarding to protect the face, chin, forehead, ears, and neck area are required by 130.7(C)(10)(c). Where the back of the head is inside the arc flash boundary, a balaclava or an arc flash hood shall be required for full head and neck protection.
c Rubber insulating gloves with leather protectors provide arc flash protection in addition to shock protection. Higher class rubber insulating gloves with leather protectors, due to their increased material thickness, provide increased arc flash protection.

NOTE:
Table 130.5(G) identifies the arc-rated clothing and other PPE requirements of Article 130 and shall be permitted to be used with the incident energy analysis method of selecting arc flash PPE.
CAUTION:
1. It is advantageous to specify or select arc-rated equipment that will be exposed to less than its rating during a fault. The testing of arc-rated clothing is based on 50% probability of success. Exceeding the minimum requirement can substantially increase the probability of success.
2. The PPE necessary to protect you, as stated on the equipment label, is typically based on the working distance. If any part of your body will be closer to the equipment than the stated working distance, an additional level of protection is necessary. This information should be included on the energized electrical work permit.
TABLE 130.5(G) Selection of Arc-Rated Clothing and Other PPE When the Incident Energy Analysis Method Is Used
Incident energy exposures equal to 1.2 cal/cm2 up to and including 12 cal/cm2
Arc-rated clothing with an arc rating equal to or greater than the estimated incident energya
Arc-rated long-sleeve shirt and pants or arc-rated coverall or arc flash suit (SR)
Arc-rated face shield and arc-rated balaclava or arc flash suit hood (SR)b
Arc-rated outerwear (e.g., jacket, parka, rainwear, hard hat liner, high-visibility apparel) (AN)e
Heavy-duty leather gloves, arc-rated gloves, or rubber insulating gloves with leather protectors (SR)c
Hard hat
Safety glasses or safety goggles (SR)
Hearing protection
Leather footweard
Incident energy exposures greater than 12 cal/cm2
Arc-rated clothing with an arc rating equal to or greater than the estimated incident energya
Arc-rated long-sleeve shirt and pants or arc-rated coverall or arc flash suit (SR)
Arc-rated arc flash suit hood
Arc-rated outerwear (e.g., jacket, parka, rainwear, hard hat liner, high-visibility apparel) (AN)e

aArc ratings can be for a single layer, such as an arc-rated shirt and pants or a coverall, or for an arc flash suit or a multi-layer system if tested as a combination consisting of an arc-rated shirt and pants, coverall, and arc flash suit.
bFace shields with a wrap-around guarding to protect the face, chin, forehead, ears, and neck area are
required by 130.7(C)(10)(c). Where the back of the head is inside the arc flash boundary, a balaclava or an arc flash hood shall be required for full head and neck protection.
cRubber insulating gloves with leather protectors provide arc flash protection in addition to shock protection. Higher class rubber insulating gloves with leather protectors, due to their increased material thickness, provide increased arc flash protection.
dFootwear other than leather or dielectric shall be permitted to be used provided it has been tested to demonstrate no ignition, melting, or dripping at the estimated incident energy exposure.
eThe arc rating of outer layers worn over arc-rated clothing as protection from the elements or for other safety purposes, and that are not used as part of a layered system, shall not be required to be equal to or greater than the estimated incident energy exposure.
