Success is often not achievable without facing and overcoming obstacles along the way. To reach our goals and achieve success, it is important to understand and resolve the obstacles that come in our way.
In this article, we will discuss the various obstacles that hinder success, strategies to overcome them, and examples of individuals who have successfully surmounted their obstacles.
1. ELECTRICAL SAFETY BASIC AWARENESS
Per OSHA 29 CFR 1910 SUBPART S
1
PPT-008-02
Bureau of Workers’ Compensation
PA Training for Health & Safety
(PATHS)
2. Electrical Injuries
AN AVERAGE OF ONE WORKER IS
ELECTROCUTED ON THE JOB EVERY DAY!
There are four main types of electrical injuries:
• Electrocution (death due to electrical shock)
• Electrical Shock
• Burns
• Falls
2
PPT-008-02
3. US fire statistics on electrical fire causes (2002-2005)
Statistics U.S. Fire Administration
Factor contributing to ignition in reported
structure fires
Fires %
unclassified electrical failure or malfunction 36,300 7
unspecified short circuit arc 21,400 4
short circuit arc from defective or worn insulation 11,400 2
arc or spark from operating equipment 4,000 1
arc from faulty contact or broken conductor 3,600 1
short circuit arc from mechanical damage 3,400 1
water caused short circuit arc 1,600 <1
3
PPT-008-02
4. How is an Electrical Shock Received?
When two wires have different potential voltages
current will flow if they are connected.
• In most household wiring the black wires
are at 110 volts relative to ground
• The white wires are at zero volts because
they are connected to ground
Contact with an energized (live) black wire
while touching the white grounded wire =
ELECTRICAL SHOCK!
4
PPT-008-02
5. Electrical Burns
• Are the most common shock
related nonfatal injury
• Occur when you touch electrical
wiring or equipment that is
improperly used or maintained
• Typically occurs on the hands
• Very serious injury that needs
immediate attention
5
PPT-008-02
6. Falls
• Electrical shock can also
cause indirect or secondary
injuries.
• Employees working in an
elevated location who
experience a shock can fall
resulting in serious injury
or even death.
6
PPT-008-02
7. Inadequate Wiring Hazards
A hazard exists when a
conductor is too small to
safely carry the current.
Example: using a portable tool
with an extension cord that
has a wire too small for the
tool
• Tool draws more current
than cord can handle =
overheating, possible fire
without tripping the circuit
breaker
• Circuit breaker could be the
right size for the circuit but
not for the smaller wire
extension cord
7
PPT-008-02
8. Hazards of Overloading
• Too many devices
plugged into circuit
= wires heat to very
high temperature =
possible fire.
• Wire insulation
melts = arcing may
occur = fire in area
where overload
exists (even inside
a wall).
8
PPT-008-02
9. Electrical Protective Devices
• Shut off electricity flow in the event of an
overload or ground-fault in the circuit.
• Include fuses, circuit breakers, and ground-
fault circuit interrupters (GFCI).
• Fuses and circuit breakers are “over current”
devices (too much current = fuses melt and
circuit breakers “trip” open).
9
PPT-008-02
10. Ground Fault Circuit Interrupter
• Protects you from dangerous electrical
shock.
• Detects a difference in current between
the black and white circuit wires (could
happen when electrical equipment is not
working properly causing a current
“leakage” known as ground fault).
• Ground fault detected = GFCI can shut
off electricity flow in as little as 1/40 of a
second protecting you from a dangerous
shock.
10
PPT-008-02
11. Examples: OSHA Electrical Requirements
GROUNDING PATH
The path to ground from circuits, equipment, and
enclosures must be permanent and continuous.
The violation shown here is an extension cord
with the third/grounding prong missing.
11
PPT-008-02
12. Examples: OSHA Electrical Requirements
• Hand-held electrical tools pose a
potential danger because they
make continuous contact with
the hand.
• To protect you from shock,
burns, and electrocution, tools
must:
o Have a 3 wire cord with ground
and be plugged into a grounded
receptacle or
o Be double insulated or
o Be powered by a low-voltage
isolation transformer
12
PPT-008-02
13. Guarding Live Parts
Must guard “live” parts of electric
equipment operating at > 50 volts
against accidental contact by:
• Approved cabinets/enclosures or
• Location or permanent partitions
(thereby only accessible to
qualified persons)
• Elevation of 8 feet or more
above the floor or working
surface
• Mark entrances to guarded
locations with conspicuous
warning signs
13
PPT-008-02
14. Guarding Live Parts
• Where electrical
equipment is in
locations that it
can suffer
physical damage
it must be
guarded.
• The violation
shown here is
physical damage
to conduit.
14
PPT-008-02
15. Cabinets, Boxes, Fittings
• Junction boxes, pull boxes, and
fittings must have approved
covers.
• Unused openings in cabinets,
boxes and fittings must be
closed (no missing “knockouts”).
• Photo shows violations of these
two requirements.
15
PPT-008-02
16. Use of Flexible Cords
• Are more vulnerable than
fixed wiring.
• Made be of industrial
commercial quality.
• May not be used as
permanent wiring.
• Improper use of flexible
cords can cause shocks,
burns, or fire.
• Approved by a recognized
testing agency.
16
PPT-008-02
17. Flexible Cords
• Uncoil an extension cord
fully before use.
• Be sure the amperage of
the cord is appropriate for

29. Top 5 – Electrical Fire Causes
1. Most electrical fires are
caused by faulty electrical
outlets and old, outdated
appliances.
Removing the grounding plug
from a cord so it can be used in
a two-prong electrical outlet can
also cause a fire.

30. Top 5 – Electrical Fire Causes
2. Light fixtures, lamps and light bulbs are another
common reason for electrical fires.
o Installing a bulb with a wattage that is too high for the
lamps and light fixtures is a leading cause of electrical
fires.
o Always check the maximum recommended bulb wattage
on any lighting fixture or lamp and never go over the
recommended amount.

31. Top 5 – Electrical Fire Causes
3. Misuse of extension cords
is another electrical fire
cause.
o Appliances should be plugged
directly into outlet and not
plugged into an extension cord
for any length of time.
o Only use extension cords as a
temporary measure.
o If you do not have the
appropriate type of outlets for
your appliances, hire an
electrician to install new ones.

32. Top 5 – Electrical Fire Causes
4. Space heaters are a major
cause of electrical fires.
o Because these types of heaters
are portable, many times
people put them too close to
combustible surfaces such as
clothing, chairs, and rugs.
o Coil space heaters are
especially dangerous. I
o f you do use space heaters,
use the radiator-type that
diffuse heat over the entire
surface of the appliance.

33. Top 5 – Electrical Fire Causes
5. Outdated wiring often
causes electrical fires.
o Breakers should be
triggered when circuits
get overloaded by too
much electricity,
o Outdated breaker boxes
often have worn
connectors that do not
work, causing the
system to overload and
start an electrical fire.
33
PPT-008-02
34. Safety
• Check the information on your cord.
o Extension cords are labeled with valuable
information as to the use, size and wattage
rating of the cord.
o Cords offered in many lengths and are labeled
with size or “gauge.”
• Determine the gauge needed. All appliances
indicate how much wattage is consumed when
operated.
34
PPT-008-02
35. Safety
• Decide whether you will be using the
appliance indoors or outdoors.
o Extension cords that can be used outdoors will
be clearly marked “Suitable for Use with
Outdoor Appliances.”
• Never use an indoor extension cord outdoors; it
could result in an electric shock or fire hazard.
35
PPT-008-02
36. Safety
• Determine how long you need the cord to
be. A cord, based on its gauge, can power an
appliance of a certain wattage only at specific
distances.
o As cord gets longer, the current carrying
capacity of the cord gets lower.
o Example: 16 gauge extension cord less than 50
feet in length can power a 1625 watt (W)
appliance; 16 gauge cord that is longer than 50
feet can only power an appliance up to 1250W.
36
PPT-008-02
37. Safety
Place the cord correctly.
o Do not place underneath carpets or heavy
furniture.
o Should not be tacked in place to a wall or taped
down.
o Should not be used while coiled or bent.
o Match the length of the cord to the length of
your needs.
37
PPT-008-02
38. Training
Train employees working with electrical
equipment in safe working practices including:
• De-energizing electrical equipment before
inspecting or making repairs
• Using electric tools in good repair
• Using good judgment when working near
energized lines
• Using appropriate protective equipment (PPE)
38
PPT-008-02
39. Summary
• Extension cords must be "of proper size and
temperature rating to withstand the electrical
load and approved by a recognized testing
agency.”
• Locally purchased extension cords may not
meet this standard.
• Always check applicable regulations/standards
before buying or using extension cords at work.

This program addresses electrical safety issues which may be found in OSHA 29 CFR 1910, Subpart S.
The intent of this program is to familiarize people with potential electrical hazards at the work site and at home.
We suggest you consult an electrician to answer specific questions which may arise.
Electrical injuries:
AN AVERAGE OF ONE WORKER IS ELECTROCUTED ON THE JOB EVERY DAY!
There are four main types of electrical injuries:
► Electrocution (death due to electrical shock)
► Electrical Shock
► Burns
► Falls
The US Fire Administration compiles statistics for various fire incidents.
These are for electrical incidents (2002-2005)
How is an electrical shock received?
When two wires have different potential voltages, current will flow if they are connected.
►In most household wiring the black wires are at 110 volts relative to ground
►The white wires are at zero volts because they are connected to ground
Contact with an energized (live) black wire while touching the white grounded wire =ELECTRICAL SHOCK!
You’re completing the circuit and the voltage wants to go to ground.
Electrical Burns
Are the most common shock related nonfatal injury
Occur when you touch electrical wiring or equipment that is improperly used or maintained
Typically occurs on the hands
Very serious injury that needs immediate attention
Falls. When a person is working at an elevated height and receives a shock, there is the likelihood they may fall from their support.
Electrical shock can also cause indirect or secondary injuries.
Employees working in an elevated location who experience a shock can fall resulting in serious injury or even death.
Inadequate Wiring Hazards contribute to overheat conditions.
A hazard exists when a conductor is too small to safely carry the current.
Example: using a portable tool with an extension cord that has a wire too small for the tool
• Tool draws more current than the cord can handle causing overheating and a possible fire without tripping the circuit breaker.
• Circuit breaker could be the right size for the circuit but not for the smaller wire extension cord.
A circuit may be overloaded, e.g. drawing more power than the wires can handle.
Too many devices plugged into circuit = wires heat to very high temperature = possible fire.
Wire insulation melts = arcing may occur = causing a fire in the area where overload exists (even inside a wall).
Electrical protective devices are meant to function in the circuit before they can contribute a shock hazard.
These devices shut off the electricity flow in the event of an overload or ground-fault in the circuit.
Include fuses, circuit breakers, and ground-fault circuit interrupters (GFCI).
Fuses and circuit breakers are “over current” devices (too much current = fuses melt and circuit breakers “trip” open).
The Ground Fault Circuit Interrupter (GFCI)
Protects you from dangerous electrical shock.
Detects a difference in current between the black and white circuit wires (could happen when electrical equipment is not working properly causing a current “leakage” known as ground fault).
Ground fault detected = GFCI can shut off electricity flow in as little as 1/40 of a second protecting you from a dangerous shock.
Examples: OSHA Electrical Requirements
GROUNDING PATH
The path to ground from circuits, equipment, and enclosures must be permanent and continuous.
The violation shown here is an extension cord with the third/grounding prong missing.
At home, check your ground wire outside the house. The wire should run in as straight a line as possible to the buried grounding stake. Some have been found to loop up to the grounding stake. News Flash-lighting does NOT make turns when going to ground! Get professional help to correct the situation.
Examples of OSHA electrical requirements.
Hand-held electrical tools pose a potential danger because they make continuous contact with the hand.
To protect you from shock, burns, and electrocution, tools must:
Have a 3 wire cord with ground and be plugged into a grounded receptacle or
Be double insulated or
Be powered by a low-voltage isolation transformer
The requirement to guard “live” parts of electric equipment operating at > 50 volts against accidental contact can be satisfied by:
Approved cabinets/enclosures or
Location or permanent partitions (thereby being only accessible to qualified persons)
Elevation of 8 feet or more above the floor or working surface to be out of direct or possible accidental contact.
Mark entrances to these guarded locations with conspicuous warning signs.
Live Parts are to be guarded!
Where electrical equipment is in locations that it can suffer physical damage it must be guarded.
The violation shown here is physical damage to conduit. It can be imagined that the wires running through this have been placed under strain. Also, the possibility exists that insulation has been compressed to the point of heating, burning through, contacting the metal sleeving. This could be a fire or shock hazard.
Cabinets, Boxes, Fittings (29 CFR 1910.305(b))
Junction boxes, pull boxes, and fittings must have approved covers.
Unused openings in cabinets, boxes and fittings must be closed (no missing “knockouts”).
Photo shows violations of these two requirements.
Flexible cords and cables are more vulnerable than fixed wiring. (29 CFR 1910.305(g))
Made be of industrial commercial quality.
May not be used as permanent wiring.
Improper use of flexible cords can cause shocks, burns, or fire.
Approved by a recognized testing agency
Extension Cords
Fully uncoil an extension cord before use. Be sure the amperage of the cord is appropriate for the job you are doing.
Do not use equipment that delivers mild electrical shocks, gives off unusual heat or odd odors. If in doubt, have it checked and repaired or replaced.
Flexible cords (extension cords)
Extension cords shall not be:
Fastened with staples, (Staples may compress the insulation around the wire. This can lead to heating and deterioration of the insulating wire)
Hung from nails, or (This does not provide a secure attachment and the wire may be subject to movement or strain if not properly secured.)
Suspended by wire. (This places 2 potential conductors within possible contact one with the other-unsafe.)
Strain Relief. Flexible cords shall be connected to devices and fittings so that strain relief is provided which will prevent pull from being directly transmitted to joints or terminal screws. (29 CFR 1926.405(g)(2)(iv).
Permissible Use: Flexible Cords (29 CFR 1926.405(g))
Pendant or fixture wiring
Portable lamps, tools or appliances
Stationary equipment to facilitate interchange
Each of the above looks at the:
Short distances between sources and use,
Low power requirements
Need to provide power temporarily until permanent tie-in is established.
Prohibited Use of Flexible Cords
These are not a substitute for fixed wiring. (Flex cord may not be up to carry same voltage as fixed arrangement.)
They are not run through walls, ceilings, floor, doors or windows. (Too easy to tamper with or come into contact with.)
They are not concealed behind or attached to building surfaces. (Subject to humidity and dampness changes.)
Electrical Extension Cords
A Homemade “Gang Box” is Not allowed in a work setting per OSHA:
29 CFR 1910.305
29 CFR 1926.405
Since every type of person, qualified or not, can make one of these, their quality can differ from person to person.
When we’re talking about electrical safety, do we really want to use any equipment described as being “homemade?”
Not only do we have the insulation removed from the orange extension cord but we also have a box with knockouts. The grounding screw is also in contact with the box.
We do not chain materials to electrical lines; if the material falls it puts a strain on the line or separates the line from its connections.
Ladders against the box contribute combustible materials should there be an electrical fire. Also, this limits access which may be required to shut the system down or isolate breakers (OSHA states there should be at least 3 feet of clearance around an electrical box).
Also, if there is a fault in the electrical box, could the current flow to the outside of the box contacting conductive materials and be a possible shock or electrocution hazard?
Another situation where combustible storage obstructs the box.
Portable power tool with damaged cord. Also appears to be resting on a conductive surface.
Right side: Missing insulation on cords.
Left side: Permanency attempted by screwing a “bridge” between extension cord and adapter. Again, “Homemade” might get you hurt!
Professionally manufactured cords must abide by specific standards. They also go through extensive quality control.
Quality Control for “homemade” stuff is usually, “Yep, looks good to me.” This does not assure safety.
Left: extension cord under carpet permits foot traffic to compress cord and insulation to the point of thinning and distressing the insulation. Potential fire and shock hazard.
Right: multiple lines into a power strip permits cords to heat up. Fire hazard.
Left: Grounding prong in receptacle. Seek professional help to remove and replace receptacle.
Right: Damaged insulation and wiring. Destroy and replace.
Left: cord is tangled; tripping hazard.
Right: multiple gang boxes showing the possibility of appliances and tools to far exceed the voltage restrictions on the line.
Top 5: Number 1 Electrical Fire Cause
Most electrical fires are caused by faulty electrical outlets and old, outdated appliances.
Removing the grounding plug from a cord so it can be used in a two-prong electrical outlet can also cause a fire.
Top 5: Number 2
Light fixtures, lamps and light bulbs are another common reason for electrical fires. Installing a bulb with a wattage that is too high for the lamps and light fixtures is a leading cause of electrical fires. Always check the maximum recommended bulb wattage on any lighting fixture or lamp and never go over the recommended amount
Top 5: Number 3
Misuse of extension cords is another electrical fire cause. Appliances should be plugged directly into outlet and not plugged into an extension cord for any length of time. Only use extension cords as a temporary measure. If you do not have the appropriate type of outlets for your appliances, hire an electrician to install new ones.
Top 5: Number 4
Space heaters are a major cause of electrical fires. Because these types of heaters are portable, many times people put them too close to combustible surfaces such as clothing, chairs, and rugs. Coil space heaters are especially dangerous. If you do use space heaters, use the radiator-type that diffuse heat over the entire surface of the appliance.

In addition, keep the following safety information in mind:
Determine how long you need the cord to be. A cord, based on its gauge, can power an appliance of a certain wattage only at specific distances.
As the cord gets longer, the current carrying capacity of the cord gets lower.
Example: 16 gauge extension cord less than 50 feet in length can power a 1625 watt (W) appliance; 16 gauge cord that is longer than 50 feet can only power an appliance up to 1250W.
Place the cord correctly.
