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.
ARC BLAST
• Arc-blasts occur from high- amperage currents arcing through the air.
This can be caused by accidental contact with energized components or equipment failure.
• A DANGEROUS PRESSURE WAVE
• A DANGEROUS SOUND WAVE
• SHRAPNEL
• EXTREME HEAT
• EXTREME LIGHT.
ELECTRIC CURRENT
• Caused by the motion of electrons
• If channeled in a given direction, a flow of electrons occurs.
Severity of the shock depends on:
Path of current through the body
Amount of current flowing through the body Length of time the body is in the circuit
Be familiar with the fundamental concepts of electricity.
Be familiar with the effects of electricity on the human body.
Be able to recognize common electrical hazards.

An arc blast or flash can occur when workers service electrical power, transmission, and distribution systems using high voltage. It is important to understand the OSHA, NFPA, IEEE and NEC requirements as well as the hierarchy of controls to reduce the risk. Understanding how to calculate a flash analysis to determine the protection boundaries, train workers on the hazards of high voltage electricity and use of personal protective equipment and clothing, and using the right tools for the job are all important steps.

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.

The tall wiring fences that surround electrical substations suggest that such places are not accessible to the public. Let it be known that substations are extremely dangerous and the safety signs will tell you that. The signs read as either “Danger”, “Caution”, “Warning”, “No Entry”, or “High Voltage Risk Ahead”. The various machineries inside the facility carry high voltage risks, and trespassers who dare to come near the place put themselves in danger.

It is necessary to take safety precautions at home since your kids might end up playing with electricity. Here are a few tips for electrical safety which you can share with your kids. Call Caddell Electric for further assistance. http://www.dallaselectricrepair.com/
Electrical equipment that is live can be exceedingly dangerous to work on.
The majority of installations and maintenance should be done dead, not live. This is a modified expectation that resulted from the realisation that working on or near live electrical equipment was causing too many fatalities or severe injuries to workers.
In the past, performing live installations and repairs was a requirement of the job for electricians.
No longer!
We have discovered the hard way that correctly shutting down machinery before working dead not only saves lives, but also ultimately saves time and money.
Here's a slideshare that explains some basics.

Hierarchical Digital Twin of a Naval Power SystemKerry Sado
A hierarchical digital twin of a Naval DC power system has been developed and experimentally verified. Similar to other state-of-the-art digital twins, this technology creates a digital replica of the physical system executed in real-time or faster, which can modify hardware controls. However, its advantage stems from distributing computational efforts by utilizing a hierarchical structure composed of lower-level digital twin blocks and a higher-level system digital twin. Each digital twin block is associated with a physical subsystem of the hardware and communicates with a singular system digital twin, which creates a system-level response. By extracting information from each level of the hierarchy, power system controls of the hardware were reconfigured autonomously. This hierarchical digital twin development offers several advantages over other digital twins, particularly in the field of naval power systems. The hierarchical structure allows for greater computational efficiency and scalability while the ability to autonomously reconfigure hardware controls offers increased flexibility and responsiveness. The hierarchical decomposition and models utilized were well aligned with the physical twin, as indicated by the maximum deviations between the developed digital twin hierarchy and the hardware.
NUMERICAL SIMULATIONS OF HEAT AND MASS TRANSFER IN CONDENSING HEAT EXCHANGERS...ssuser7dcef0
Power plants release a large amount of water vapor into the
atmosphere through the stack. The flue gas can be a potential
source for obtaining much needed cooling water for a power
plant. If a power plant could recover and reuse a portion of this
moisture, it could reduce its total cooling water intake
requirement. One of the most practical way to recover water
from flue gas is to use a condensing heat exchanger. The power
plant could also recover latent heat due to condensation as well
as sensible heat due to lowering the flue gas exit temperature.
Additionally, harmful acids released from the stack can be
reduced in a condensing heat exchanger by acid condensation. reduced in a condensing heat exchanger by acid condensation.
Condensation of vapors in flue gas is a complicated
phenomenon since heat and mass transfer of water vapor and
various acids simultaneously occur in the presence of noncondensable
gases such as nitrogen and oxygen. Design of a
condenser depends on the knowledge and understanding of the
heat and mass transfer processes. A computer program for
numerical simulations of water (H2O) and sulfuric acid (H2SO4)
condensation in a flue gas condensing heat exchanger was
developed using MATLAB. Governing equations based on
mass and energy balances for the system were derived to
predict variables such as flue gas exit temperature, cooling
water outlet temperature, mole fraction and condensation rates
of water and sulfuric acid vapors. The equations were solved
using an iterative solution technique with calculations of heat
and mass transfer coefficients and physical properties.

deaths result from
electrocutions
6. What is electricity?
Electricity is a natural
energy force.
Electricity is also a man
made energy force.
It is essential to modern
life and taken for granted
everyday.
7. What is Electricity?
Electricity flows through
conductors.
Conductors include
metals, water, the Earth
and the human body.
Electricity must have a
complete circuit or path
to flow.
8. How Electricity Works
When electrical tools are
working properly a
complete circuit is
maintained between the
tool and the energy
source.
9. How Electricity Works
However, if the tool is
damaged the person may
come in contact with the
electricity and can
become a path for the
current.
The person will be
shocked!
10. Electrical Hazards
The following is a list of a common electrical hazards
found on construction sites:
Improper grounding
Exposed electrical parts
Inadequate wiring
Overhead power lines
Damaged insulation
Overloaded circuits
Wet conditions

33. Wet Conditions
Always avoid using tools
in wet locations.
Water increases the risk
of electric shock.
34. Overhead Power Lines
Survey the site for
overhead power lines.
Never store materials or
equipment under overhead
power lines.
35. Overhead Power lines
Maintain a distance of at
least 10’ between tools
and equipment and
overhead power lines.
Shocks and electrocutions
occur where physical
barriers are not in place
to prevent contact with
the wires.
36. Overhead Power lines
Maintain safe distances
between scaffolding and
overhead power lines.
37. Overhead Power lines
Overhead power lines are
very dangerous.
