SafetyQuestion 430 of 521
Under Cal/OSHA and NFPA 70E, the primary/preferred way to protect workers from electrical hazards is to:
a.De-energize the equipment and establish an electrically safe work condition whenever it is feasible
b.Put on an arc-flash suit and work the equipment while energized
c.Use insulated tools only and skip other protections
d.Post a warning sign near the panel
Explanation
The hierarchy of controls makes de-energizing and creating an electrically safe work condition the primary protection; energized work is only permitted when de-energizing is infeasible or introduces greater hazards. PPE, insulated tools, and signs are supplemental and do not replace de-energizing when it can be done.
