Updates
to NFPA 70E standards.
August 2003 Below
|
|
|
1. |
A major change to the standard will be in the order of the
three parts: Part I "Installation Safety Requirements for
Electrical Installations" will become Part III, Part II will
become Part I and Part III will now be Part II.
The intention of this change is to make the NFPA 70E consistent
with the NEC 2002 standard. |
|
|
2. |
No
changes will be made to the " Hazard Risk Category Table"
|
|
|
3. |
No
additional risk categories will be added, i.e. Risk Category
4 remains the highest.
Members of the panel feel that there are additional risks
associated with arc blasts of greater magnitude that are not
addressed in this standard and did not want to condone putting
worker in front of such blast. |
|
|
4. |
The
requirements for multiple layered garments are removed. FR
fabrics development has outpaced the development of the standard.
In the past, a multiple layered garment was a necessity, but
today we can use a more comfortable single layer garment that
offers equal protection. |
|
|
5. |
The
will be a Hot Work Permit requirement.
The panel feels that this requirement will reduce the number
of jobs where electricians work on energized equipment. It
will become the responsibility of the supervisor to make the
decision if hot work is justified or not. |
|
| Other minor
changes will also be made that should make reading and understanding
the standard easier. |
