Am I In Danger?
Due to the dynamic, rugged nature of construction work, normal
use of electrical equipment at your site causes wear and tear that
results in insulation breaks, short-circuits, and exposed wires [for
additional information, see Flexible
Cords and Power
Tools]. If there is no ground-fault protection, these can
cause a ground-fault
that sends current through the worker's body, resulting in
electrical burns, explosions, fire, or death.
How Do
I Avoid Hazards?
- Use
ground-fault circuit interrupters (GFCIs)
on all 120-volt, single-phase, 15- and 20-ampere receptacles, or
have an assured equipment grounding conductor program (AEGCP).
- Follow manufacturers' recommended testing procedure to insure GFCI is working correctly.
- Use double-insulated
tools and equipment, distinctively marked.
- Use tools and equipment according to the instructions included in
their listing, labeling or certification.
- Visually inspect all electrical equipment before use. Remove from
service any
equipment with frayed cords, missing ground prongs, cracked tool
casings, etc. Apply a warning tag to any defective
tool and do not use it until the problem has been corrected.

These receptacles are not protected by a GFCI. If there is no AEGCP on this jobsite this
is a violation.
