INSPECTION, INSTALLATION AND USE
OF ELECTRICAL EQUIPMENT
• The following must be inspected before
each use:
– Electrical extension cords or temporary wiring,
– any equipment connected by cord and plug, and
– any portable electric hand tool.
COVERS OR ENCLOSURES
• All energized parts of electrical equipment
or connections must be guarded to prevent
accidental contact by a worker
EXTENSIONS CORDS USED AS
TEMPORARY WIRING
• Extension cords used must be designed for
the intended application
• Plugs and the covering or electrical
insulation material of the cord must be in
good condition (no evidence of damage)
• Extension cord plugs must always have a
ground pin
Ground Pin
PROTECTION OF EXTENSION CORDS
(TEMPORARY WIRING)
• When run through holes, cords shall be
protected from sharp edges
• Never submerge extension cords in water
• Do not expose cords to excessive heat,
unless the cord has been designed for high
temperature applications

PLANNING THE WORK
• Plan ahead to control any potential
electrical hazard
• The minimum working distance from
overhead power lines is 10 feet
• If you have to work at less than 10 feet from
an overhead power line, then the electrical
current must be disconnected
ACCESS
• Electrical extension cords used in the
working area and in passage ways to the
work area shall be installed so that:
– they do not become a potential hazard for
workers (tripping)
– they are not physically damaged by traffic

TEMPORARY ELECTRICAL
RECEPTACLES
• Shall be protected with approved covers
• If metal covers are used, they shall be
grounded
WHAT IS A GFCI?
• GFCI is a device that senses small
imbalances in an electrical circuit caused by
the electrical current leaking to ground.
– If this imbalance occurs, the GFCI shuts off the
electricity within a fraction of a second
ASSURED EQUIPMENT GROUNDING
PROGRAM
• An assured equipment grounding program
is allowed by OSHA but rarely put into
practice due to:
– The time required for an adequate
implementation and follow up
– The program may provide a false sense of
safety
