Practical Electrical Substation Safety for Engineers and TechniciansLiving Online
Electrical substation safety is an important issue in utility networks as well as large industrial installations and requires adequate attention in the stages of system planning, design, installation, operation and maintenance. A number of serious accidents including fatalities occur every year in industrial establishments due to accidents involving electricity, resulting in huge financial losses and wasted man-hours. Electrical safety is a well-legislated subject and the various Acts and Regulations lay a lot of stress on the responsibility of both employers and employees in ensuring safe working conditions.
In this workshop, we will take a look at the theoretical aspects of safety as well as the practical and statutory issues. Safety is not simply a matter of taking precautions in the workplace. It has to start at the stage of equipment design. Safety should be built into the design of electrical equipment and it is the responsibility of every manufacturer of electrical equipment to remove every possible hazard that can arise from its normal use. Correct selection and application of electrical machinery is also important for ensuring safety. A thorough inspection during initial erection and commissioning as well as on a periodic basis thereafter is also very essential to ensure safety. Batteries used in substations need particular attention since they contain toxic materials such as lead, corrosive chemicals such as acid or alkali.
Electrical safety is not just a technical issue. Accidents can only be prevented if appropriate safety procedures are evolved and enforced. This includes appropriate knowledge of equipment and systems imparted through systematic training to each and every person who operates or maintains the equipment. We will cover all these aspects in detail.

Electric shock is the effect produced on the body and particularly on the nervous system by an electrical current passing through it. The effect depends on the current strength which itself depends on the voltage and body resistance.
Failing to take the necessary precautions can lead to:
- injury or death
- fire or property damage
Common causes of electrocution are:
- Making contact with overhead wires
- Undertaking maintenance on live equipment
- Working with damaged electrical equipment - extension leads, plugs and sockets
- Using equipment affected by rain or water ingress
There are four main types of electrical injuries:
-Electrocution (death due to electrical shock)
-Electrical Shock
-Burns
-Falls
An arc flash happens when electric current flows through an air gap between conductors.

4
5. Basic Concept of Electricity
• Electricity is the flow of
electrons (current) through a
conductor.
• Requires a source of power:
usually a generating station.
• Travels in a closed circuit.
• When you become part of the
circuit, the injury may be fatal.
5
6. Hazard Recognition
Cords & Equipment
• Power tools and extension cords
must be inspected each time
they are used.
• They must be taken out of
service immediately upon
discovery of worn or broken
insulation.
6
7. Hazard Recognition
Electrical Panels
• Electric panels must be kept
clear of any obstructions at all
times.
• Storage is not allowed in
electrical vault or service
panel rooms.
• Find another place for
storage of materials,
products, etc.
7
8. Hazard Recognition
Trip Hazards
• Don’t cause tripping hazards or
create pinch points for cords.
• If you must run a cord
across the floor, protect your co-
workers by covering the cord
appropriately.
8
9. Hazard Recognition
Exposed Wiring
• Assume all exposed wiring is
energized until proven
otherwise.
• Stop, protect the area, and
contact supervision if you
encounter this situation.

11. Electrical Injuries
11
There are four main types of electrical injuries:
• Electrocution (death due to electrical shock)
• Electrical Shock
• Burns
• Falls
12. What Causes Shock?
Shocks occur when a person’s body completes the current path
with:
• both wires of an electric circuit;
• one wire of an energized circuit and the ground;
• a metal part that accidentally becomes energized due, for
example, to a break in its insulation; or
• another “conductor” that is carrying a current.
12
13. Electric shock
• 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!
13
14. Effects of Electric Current in the
Human Body
Current Reaction
1 milliampere Faint tingle
5 milliamperes Slight shock felt; not painful but disturbing.
Average individual can let go. Strong involuntary
reactions can lead to other injuries.
6–25 milliamperes
(women)
Painful shock, loss of muscular control*
9–30 milliamperes (men) The freezing current or “let-go” range.*
Individual cannot let go, but can be thrown
away from the
circuit if extensor muscles are stimulated.
50–150 milliamperes Extreme pain, respiratory arrest, severe
muscular contractions.
Death is possible.
14
15. Effects (conti…)
1,000-4,300 milliamps (1-4.3 amps)
• Arrhythmic heart pumping action, muscles contract, and
nerve damage occurs. Death is likely.
10,000+ milliamps (10 amps)
• Cardiac arrest and severe burns occur. Death is probable.
15
16. Electric Shock
Low voltage can be extremely dangerous because the degree of
injury depends not only on the current, but on the length of
time in contact with the circuit.
• Example:
• A current of 100mA applied for 3 seconds isas
dangerous as 900mA applied for 0.03 seconds.
• Low Voltage Does Not Mean Low Hazard.
16
17. Electrical Burns
The most common shock related, nonfatal injury is a burn.
Burns caused by electricity may be of three types:
• Electrical burns
• Arc burns
• Thermal contact burns
Electrical burns need to be given immediate medical
attention.
17
18. Electric Burn
• Electrical burns occur when a person touches electrical
wiring or equipment that is used or maintained improperly.
• Typically such burns occur on the hands.
• Clothing may catch on fire and a thermal burn may result
for the heat of the fire.
18
19. Arc Blast
• An arc-blast is a luminous
electrical discharge that occurs
when high voltages exist across a
gap between conductors and
current travels through the air.
• Temperatures as high as 35,000
F have been reached in arc-
blasts.
19
20. Arc Blast
The three primary hazards associated with an arc-blast
are:
• Arching gives off thermal radiation (heat) and
intense light which causes burns.
• A high voltage arc can produce a considerable
pressure wave blast.
• Example: A person 2 ft. away from a 25,000-amp
arc feels a force of about 480 lbs on the front of
the body.
• May cause copper and aluminum components to
• The molten metal can be blasted great distances
by the pressure wave.
20
21. Falls
• Electric shock can also cause
indirect injuries.
• Workers in elevated locations
who experience a shock may fall,
resulting in serious injury or
death.
21
23. Insulation
• Plastic or rubber coverings that does not conduct electricity.
• Insulation prevents live wires from coming in contact with
people thus protecting them form electrical shock.
23
24. Grounding
• Grounding is another method
of protecting you from electric
shock.
• However, it is normally a
secondary protective
measure.
• It furnishes a second path for
the current to pass through
from the tool or machine to
the ground.
24
25. Guarding
Guarding involves locating or enclosing
electric equipment to make sure people don’t
accidentally come into contact
with its live parts.
Guarding include:
• Boxes
• Partitions
• Warning sign boards
Such as “Danger/High Voltage/Keep Out.”
25
26. GFCI (Ground Fault Circuit Interrupter)
• Detects the difference in current
between two circuits wires.
• This difference in current could
happen when electrical
equipment isn’t working correctly.
• GFCI are set at about 5mA and
are designed to protect workers
and not equipment.
26
27. Fuses and Circuit Breakers
• Fuses and circuit breakers are intended primarily for the
protection of conductors and equipment.
• They prevent over-heating of wires and components
that might otherwise create hazards for operators.
• They also open the circuit under certain hazardous
ground-fault conditions.
27
28. Safe Work Practices
Electrical accidents are largely preventable through safe work
practices.
• De-energizing electric equipment before inspection or repair,
• keeping electric tools properly maintained,
• exercising caution when working near energized lines
• maintain a safe distance from energized part
• Follow SSOW
28
29. Safe Work Practices
Employees and others working with electric equipment need
to use safe work practices.
• Plan your work by yourself and with others.
• Lock out Tag out circuits and equipment.
• Do not work in wet conditions.
• Avoid overhead power lines.
• You should be at least 10 feet away from high-voltage
transmission lines.
• Use proper wiring and connectors
• Avoid overloading circuits.
• Never use a three prong plug with the third prong broken off.
29
30. Safe Work Practices
• Use and maintain tools properly.
• Inspect tools before using them.
• Damaged tools must be removed from service.
• Using appropriate personal protective equipment
• Wear safety glasses to avoid eye injury.
• Wear proper foot protection.
• Wear a hard hat.
30
32. How to respond a problem
In the event of an electrical fire:
• Activate the fire alarm system
• If you know how to use an extinguisher, use a CO2 or dry
chemical fire extinguisher
• Alert everyone in the area to evacuate
• Call EMERGENCY SERVICES or HSE TEAM
• If you are not sure about using a fire extinguisher, leave the
area and close any doors behind you
32
33. Summary
• Electricity will try to reach ground even if it means going
through a person
• Even the “small” voltage from your home can cause serious
injury
• Always inspect power tools and cords before each use and
do not use them if damaged
• Do not attempt to repair electrical equipment
• unless you are trained and qualified
• Always use lockout/tagout procedures to de- energize
electrical systems
33
34. Summary
• Use electrical tools and equipment that are protected by a
GFCI
• Review your assignments with your supervisors
• Utilize correct PPE
• Report all problems to your supervisors
• If at all in doubt, ask questions
34
Editor's Notes
Electricity travels in closed circuits, normally through a conductor. But sometimes a person’s body — an efficient
conductor of electricity — mistakenly becomes part of the electric circuit. This can cause an electrical shock. Shocks
occur when a person’s body completes the current path with:
• both wires of an electric circuit;
• one wire of an energized circuit and the ground;
• a metal part that accidentally becomes energized due,
for example, to a break in its insulation; or
• another “conductor” that is carrying a current.
When a person receives a shock, electricity flows between parts of the body or through the body to a ground or the earth.
