QUESTION: For a insulated energized (over 50v) cable, is OSHA saying that the cable is an Exposed Energized conductor but NFPA 70E is saying that is NOT an Exposed Energized conductor?
OSHA's 1910.269 definition of Exposed is
OSHA's 1910.269 definition of Isolated is
o Isolated. Not readily accessible to persons unless special means for access are used.
OSHA's 1910.269 definition of Guarded is
o Guarded. Covered, fenced, enclosed, or otherwise protected, by means of suitable covers or casings, barrier rails or screens, mats, or platforms, designed to minimize the possibility, under normal conditions, of dangerous approach or inadvertent contact by persons or objects.
One of the interpretations I saw from OSHA stated:
NFPA 70E's definition of Exposed is
So ..... it seems to me that OSHA says exposed is "not isolated or guarded" and NFPA 70E says exposed is "not guarded, isolated or insulated".
OSHA's 1910.269 definition of Exposed is
- Exposed. . . . Not isolated or guarded.
OSHA's 1910.269 definition of Isolated is
o Isolated. Not readily accessible to persons unless special means for access are used.
OSHA's 1910.269 definition of Guarded is
o Guarded. Covered, fenced, enclosed, or otherwise protected, by means of suitable covers or casings, barrier rails or screens, mats, or platforms, designed to minimize the possibility, under normal conditions, of dangerous approach or inadvertent contact by persons or objects.
One of the interpretations I saw from OSHA stated:
- 1910.269(l)(2) Interpretation: An employee who is "exposed to contact" with an energized part under this definition is still "exposed to contact" with the energized part even if insulation covers the part, the employee or both. See §1910.269(x) (defining "exposed" as not isolated or guarded; merely covering a conductor or an employee with insulation does not provide guarding or isolation).
NFPA 70E's definition of Exposed is
- Capable of being inadvertently touched or approached nearer than a safe distance by a person. It is applied to electrical conductors or circuit parts that are not guarded, isolated or insulated.
So ..... it seems to me that OSHA says exposed is "not isolated or guarded" and NFPA 70E says exposed is "not guarded, isolated or insulated".
