REDUCTION OF
TOUCH & STEP POTENTIAL:
Voltages generated from a lightning
strike or electrical equipment
could cause injury and/or death to
humans and animals.
Installation of a close grid earth mat
effectively reduces voltages to a
safe level.

ARTIFICIAL INCREASE OF
SURFACE RESISTANCE:
By increasing the surface resistivity
of the soil outside a structure may
reduce the life hazard.
Equipotential bonding of connected
services at entrance will benefit
anyone inside the structure.
