The new edition of NFPA 70E has many changes but the most relevant ones related to arc flash protective clothing are:
- The term Hazard Rick Category or HRC as it’s known in the industry has been changed. The new title for this is PPE Category. The purpose and ratings used for the newly named PPE Categories remain the same, other than category “0” has been eliminated. Categories 1, 2, 3, & 4 have the same requirements and the same minimum arc ratings.
- In the section titled coverage, a phrase has been added that states “shirts shall be tucked into pants”.
There are many other word changes throughout the document but these two are in my opinion the most noticeable ones related to protective clothing.
