This training presentation covers the basic on arc flash and other electrical hazards, including the effects of an arc flash incident and how to determine shock and flash protection boundaries for a safe workplace
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. Learn more about arc blast/flash in this presentation. If you need advice or help with electrical safety, contact our staff of CSPs at The Windsor Consulting Group, Inc. We have past performance working with contractors near powerlines and underground utilities.
Arc flash incidents can be costly in terms of personnel injury and equipment repair/replacement. This presentation provides an overview of the NFPA 70E 2012 Standard for Electrical Safety in the Workplace and the requirements of the standards, which are intended to better protect electrical workers from injury when they work on energized electrical equipment. This includes all aspects of facility and employer responsibilities for compliance to the NFPA 70E standards, as well as the current status of OSHA enforcement of these standards.

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

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.

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.
Many workers working on energised equipment are injured and/or killed each year. Several of these casualties are a result of arc flash.
Arc Flash is considered as one of the most destructive and dangerous instances when dealing with electrical wirings. A single occurrence can destroy metals and it has the ability to kill a person if not protected by Arc Flash Clothing. An arc flash can create an arc blast that can shatter anything because it is as hot as the as surface of the sun. This kind of heat can destroy metals instantly and completely burn a body beyond recognition.
Arc Flash ProtectionSerious injuries are caused by the arc flash:
Burns
Respiratory system damage
Hearing damage
Skin penetration from flying debris
Eye and face injuries
An arc flash may happen instantly and if the worker does not have the correct protection, they will already be dead when the arc flash hits them.
The use of Arc Flash Protective Equipment will lessen the damages caused by an arc flash because all of these equipments are solely made to withstand the heat.
Typical Arc Flash Clothing Applications
Working on electrical systems and switchrooms at 500 volts, live testing and proving dead on electrical systems, fitting and removal of LV-HV earths on electrical systems, working on panels/control circuits with exposed energised conductors, removal of bolted covers from energised electrical equipment, racking in/out of switchgear, racking in/out of starters and control gear, live testing and proving dead on electrical systems 11-33kV - T&D UK stock a broad range of Arc Flash Clothing and PPE.
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.

The electrical arc creates a pressure wave. The incident energy is the energy of this arc-flash coming into contact with a surface. Essentially an electric arc creates a radiation burn which accounts for the internal burns a person can receive when exposed to an electrical arc flash.

• As much as 80% of all electrical injuries are burns resulting
from an arc flash and ignition of flammable clothing
• Arc temperature can reach 35,000°F - this is four times
hotter than the surface of the sun
• Fatal burns can occur at distances over 10 ft

5. Arc Blast
• An arc fault develops a “pressure wave”
• Sources of this blast include:
– Copper expands 67,000 times its original volume when
vaporized
– Heat from the arc, causes rapid air expansion
• This may result in a violent explosion of circuit
components and thrown shrapnel
• The blast can destroy structures, knock workers from
ladders, or across the room
