70E PPE

[necasparky]

Are any members using even level 2 ppe for arc flash protection on your jobs? Have not seen a one in Central NJ . I thought even a 240v hot control panel troubleshoot required level 2? Face sheild, rubber and leather gloves, ect. Any sightings?

from the 2002 NFPA 70-E.....
Just because you have not seen it, does not mean it is not required...as an Instructor of 70-E you must be a Qualified Person and such would be famaliar with the following Risk Cat. Tables....

Table 3-3.9.1 [pg 55 ]
working on up to 240 voltage testing is a Risk 1..no face shield, if it is greater than 240V then it is risk 2 and face shield is required....Rubber Gloves are Always required...

I once saw some guys working on live 4180V switchgear without so much as any PPE except safety glasses and steel toes. Very scary.

From 2004 NFPA 70E Table130.7(C)(9)(a):

Panelboards or Switchboards Rated >240 V and up to 600 V (with molded case or insulated case circuit breakers) - Notes 1 and 3

Work on energized parts, including voltage testing

The required Hazard/Risk Catagory is 2*

2* means that a Double-layer switching hood and hearing protection are required for this task in addition to the other Hazard/Risk Catagory 2 requirements of Table 130.7(C)(10).

Note 3 says: For <10kA short circuit current available, the hazard/risk catagory required may be reduced by one number.
