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.
MORE INFORMATION: http://www.idc-online.com/content/practical-electrical-substation-safety-engineers-and-technicians-28
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.

Workplace Hazard & Solutions (Housekeeping, Working at height, FIRE etc)
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

Embracing GenAI - A Strategic ImperativePeter Windle
Artificial Intelligence (AI) technologies such as Generative AI, Image Generators and Large Language Models have had a dramatic impact on teaching, learning and assessment over the past 18 months. The most immediate threat AI posed was to Academic Integrity with Higher Education Institutes (HEIs) focusing their efforts on combating the use of GenAI in assessment. Guidelines were developed for staff and students, policies put in place too. Innovative educators have forged paths in the use of Generative AI for teaching, learning and assessments leading to pockets of transformation springing up across HEIs, often with little or no top-down guidance, support or direction.
This Gasta posits a strategic approach to integrating AI into HEIs to prepare staff, students and the curriculum for an evolving world and workplace. We will highlight the advantages of working with these technologies beyond the realm of teaching, learning and assessment by considering prompt engineering skills, industry impact, curriculum changes, and the need for staff upskilling. In contrast, not engaging strategically with Generative AI poses risks, including falling behind peers, missed opportunities and failing to ensure our graduates remain employable. The rapid evolution of AI technologies necessitates a proactive and strategic approach if we are to remain relevant.

2024.06.01 Introducing a competency framework for languag learning materials ...Sandy Millin
http://sandymillin.wordpress.com/iateflwebinar2024
Published classroom materials form the basis of syllabuses, drive teacher professional development, and have a potentially huge influence on learners, teachers and education systems. All teachers also create their own materials, whether a few sentences on a blackboard, a highly-structured fully-realised online course, or anything in between. Despite this, the knowledge and skills needed to create effective language learning materials are rarely part of teacher training, and are mostly learnt by trial and error.
Knowledge and skills frameworks, generally called competency frameworks, for ELT teachers, trainers and managers have existed for a few years now. However, until I created one for my MA dissertation, there wasn’t one drawing together what we need to know and do to be able to effectively produce language learning materials.
This webinar will introduce you to my framework, highlighting the key competencies I identified from my research. It will also show how anybody involved in language teaching (any language, not just English!), teacher training, managing schools or developing language learning materials can benefit from using the framework.

Operation “Blue Star” is the only event in the history of Independent India where the state went into war with its own people. Even after about 40 years it is not clear if it was culmination of states anger over people of the region, a political game of power or start of dictatorial chapter in the democratic setup.
The people of Punjab felt alienated from main stream due to denial of their just demands during a long democratic struggle since independence. As it happen all over the word, it led to militant struggle with great loss of lives of military, police and civilian personnel. Killing of Indira Gandhi and massacre of innocent Sikhs in Delhi and other India cities was also associated with this movement.

2. Electricity is an important part of our
modern world and sometimes it is easy
to forget just how dangerous it can be.
Given the correct circumstances,
electricity can cause serious injuries or
even death.
Electrical Safety
3. • Electrocution is the cause of
12% of all workplace deaths
among young workers.
• Electrocution is the third
leading cause of work-related
deaths among 16 and 17-year-
olds.
Electrical Safety
4. The most common types of electrical injuries are:
• Electrical shock
• Electrocution (death due to
electrical shock)
• Burns
• Falls
Electrical Injuries
5. Touching a live wire and an
electrical ground will cause a
shock.
Electrical Shock
6. Touching two live wires of
different voltages will cause
electrical shock.
Electrical Shock
7. The severity of the shock depends on:
• Path of the current through your body
• Amount of current flowing
through your body
• Length of time your body is in contact
with the circuit
Electrical Shock
LOW VOLTAGE DOES NOT
MEAN LOW HAZARD
8. Burns are the most common injury caused by
electricity. The three types of burns are:
Burns
• Electrical burns
• Arc burns
• Thermal contact burns
Electrical burns can occur when
you come into direct contact
with electricity.
9. An arc occurs when there is a gap
between conductors and current
travels through the air.
Burns
• Electrical burns
• Arc burns
• Thermal contact burns
11. Another common type of electrical
injury is falling.
Workers who experience a shock on
elevated work surfaces such as
platforms, ladders or scaffolds can
fall resulting in serious injury or
death.
Falls
12. To avoid injuries, you should be aware of electrical hazards.
Some of the most common electrical hazards are:
• Exposed electrical parts
• Overloaded circuits
• Defective insulation
• Improper grounding
• Damaged power tools
• Overhead power lines
• Wet conditions
Electrical Hazards
Let’s take a closer look at each of
these hazards.
13. Exposed electrical parts can include:
• Breaker boxes without a cover
• Electrical terminals in motors,
appliances, and electronic equipment
Exposed Electrical Parts
14. Overloading a circuit increases the potential for
fires to occur. Overload hazards exist if:
• Too many devices are plugged into a circuit
• The wire insulation melts
• An improper overcurrent protection
device is used
• No overcurrent protection device is
used
Overloaded Circuits
15. Overcurrent protection devices include:
• Circuit breakers
Overloaded Circuits
• Fuses
• Ground fault circuit
interrupters (GFCI)
A circuit breaker automatically “trips”
and shuts off the current in a circuit if
it becomes overloaded.
16. A fuse contains an internal part that melts and shuts off the
current if there is an overload.
• Circuit breakers
• Fuses
Overloaded Circuits
• Ground fault circuit interrupters
17. A ground fault circuit interrupter (GFCI)
detects current leaking from a circuit to
ground and shuts the current off.
• Circuit breakers
• Fuses
• Ground fault circuit interrupters
Overloaded Circuits
Receptacle type
18. Defective Insulation
To protect you, electrical wires are
insulated by a plastic or rubber
covering. Insulation prevents
conductors from coming in contact
with each other and with people.
Make sure the insulation of tools and
cords you are using is not damaged.
19. Grounding
When an electrical system is
properly grounded, there is a path
that allows the current to travel to
the earth (the ground).
When any electrical system is
not properly grounded, a hazard
exists.
20. Power tools that are damaged or not
properly maintained can cause you
to be seriously injured.
If you touch a metallic part of a
power tool that is energized because
of damaged insulation or improper
grounding, you could be shocked.
Power Tools
21. Power Tools
To protect you from shock,
burns and electrocution, tools
must:
• Have a three-wire cord with
ground and be plugged into a
grounded receptacle.
• Be double insulated.
• Be powered by a low-voltage
isolation transformer.
22. Overhead Power Lines
Overhead power lines are not usually
insulated, and cause more than half of all
electrocutions.
23. Wet Conditions
Wet conditions are hazardous because you can become
an easy path for electrical current.
There are many circumstances that create wet
conditions:
• Standing in water
• Wet clothing
• High humidity
• Perspiration
24. Safe Work Practices
• Inspect cords before each use
• Never overload a circuit
• Stay away from all
unguarded conductors
• To unplug, pull on the plug, not the
cord
• Don’t wear jewelry or use other metal
objects around electrical equipment
You can StartSafe and StaySafe by using
the following safe work practices:
25. Training concerning electricity is very important.
Training for employees working with electrical
equipment must include how to:
• De-energize the equipment
• Use lockout and tag procedures
• Use insulating protective
equipment
• Maintain a safe distance from
energized parts
• Use appropriate PPE
Safe Work Practices: Training

34. Safe Work Practices: Lockout/Tagout
• Turn off the power supply
• Put a lock on all power sources
to the circuit
• Apply a tag
• Test the circuit
When performing lockout/tagout on circuits, trained
employees will do the following:
35. The most effective way to protect against
electrical hazards is to use LO/TO.
Your facility will have specific requirements for
LO/TO. Always comply with the requirements.
Only LO/TO qualified employees may work
under the protection of a LO/TO.
LO/TO accomplishes a zero energy state and
there is no electrical hazard.
You are required to comply with all LO/TO
requirements.
Failure to comply can result in injury or
death!
DO NOT OPERATE!
36. Lockout/Tagout
Your personal lock and personal
danger tag is what protects you
from systems being re-energized
while you are working on them.
You are the only person
authorized to remove them
except under specially controlled
conditions.
If you don’t install them, you
are not protected!
37. A Ground Fault Circuit Interrupter (GFCI) is
a very effective device to protect employees in
the work place from electrical shock.
The number of deaths from electrical shock in the work
place has been cut in half since GFCIs have been
introduced.
GFCIs are required for all maintenance activities.
GFCIs protect you from electrical shock by tripping on
current leakage to ground, which may be through you.
Plugging one GFCI into another one does not create a
hazard. The most sensitive one will trip first.
GFCIs may be permanently installed in the facility or a
portable device. – Use them.
38. Use of Specific Safety-Related
Equipment and Work Practices
GFCIs
Ground Fault Circuit Interrupters (GFCIs) are
required for all 125-volt, single phase, 15 and
20-ampere receptacle outlets used for
temporary electric power, or as an extension to
the power supply cord.
Test Before Use. Push the test button and
verify the GFCI has shut off by plugging a safe
device into it (i.e. portable lamp or tool). If it
doesn’t shut off, don’t use it. Reset it. If it
turns on, it is safe to use.
Report a malfunctioning GFCI to the
designated facility organization.
39. GFCIs
Most facilities will allow resetting
the GFCI one time. Verify with
your facility.
If it trips a second time, have it
evaluated by a qualified electrical
worker.
It may have tripped to save your
life!
Repeated resetting is not allowed.
40. Circuit Breaker Tripping
Anytime a circuit has been de-
energized by the operation of an over
current protective device (such as a
fuse or circuit breaker) by a short
circuit or ground-fault, the circuit
must be checked by a qualified person
to determine if it can be reenergized
safely.
The repetitive manual re-closing of
circuit breakers or reenergizing
circuits through replacing fuses is
prohibited.
41. If you are allowed to reset circuit
breakers or other electrical switches,
position yourself in the safest location
possible.
Never stand directly in front of or
reach across the device.
Some facilities have specific
requirements for who is allowed to
operate breakers and disconnects.
Make sure you know the requirement
before performing these actions.
Circuit Breaker Tripping
42. Moisture provides a conductive path
that could result in death.
Never work with wet tools or clothing.
Remove Your Jewelry.
43. Use of Specific Safety-Related
Equipment and Work Practices
Portable Electric Equipment and
Flexible Cord Set requirements:
The user must visually inspect the
equipment for defects and damage
before they are used on any shift.
If the tool or cord set is damaged, take
it out of service or have it repaired.
44. Portable Electric Tools -
Things to look for:
Damaged/Broken case
Ground prong missing
on three-prong plugs.
Some tools are double
insulated and won’t
have a ground prong.
That’s OK.
Damaged Cord – outer
sheath broken
45. Cords – Items to consider before use.
1. Use per Listing and Labeling
2. Inner wires exposed – Don’t use.
3. Plug not fully seated – Don’t use.
4. Cords run through doors / pinch points – Don’t use.
5. Outer sheath damaged – Don’t use.
6. Cord tightly coiled may cause a problem – Don’t use.
7. Tightly coiled cord that had a meltdown because it
couldn’t cool properly when overloaded.
8. Cords must be GFCI protected or under an Assured
Equipment Ground Conductor program.

AWG #16 — 25 Feet
AWG #14 — 50 Feet
AWG #12 — 75 Feet
AWG #10 — 100 Feet
47. Extension cords shall:
Be protected from physical damage at all times.
Be inspected before use.
Be routed so trip, pinch, abrasion, snagging, etc. cannot
occur.
Not be used as a substitute for permanent wiring.
Be suitable for the environment i.e. outside, wet, sunlight,
etc.
Shall have slack – not drawn out tight.
Shall be unplugged by grasping the plug not the cord.
48. Ladders used around electrical hazards
must have non-conductive side rails.
Ladders with non-conductive side rails
that are contaminated with paint,
greases or other coatings may no longer
be non-conductive. Check them out.
Stay away from exposed energized
equipment.
Always look up before you lift or climb
up.
49. Be aware of overhead exposed
energized equipment such as
overhead lines, cords, or overhead
crane rails.
Minimum approach distance to
overhead lines below 72,500 volts is
10 feet. (Limited Approach
Boundary - 70E)
There may be other requirements that apply to approach distances to
overhead lines. Make sure you inquire about these requirements.
Possible examples may include:
The use of a designated spotter.
Approach distances may be different than 70E requirements.
Overhead utilities may be under separate management.
Look Up and Stay Alive!
50. The National Electrical Code
(NEC) has specific clearance
requirements around electrical
equipment to maintain safe
working clearances for electrical
workers. These are dedicated
spaces and include width, height,
and depth requirements. The
clearance distances are based on
configuration and voltage level.
You must keep these spaces clear. Check with
a qualified electrical worker to ensure you do
not store or install materials and equipment in
theses dedicated spaces.
51. Batteries present special hazards in the work place. They
may contain an acid or an alkaline substance in the
electrolyte. If you get electrolyte on you, rinse with water
for 15 minutes then get medical help. Failure to do this
may lead to severe burns or blindness.
Most batteries give off explosive
gasses when charged. Make sure
adequate ventilation is available.
Don’t cause sparks or flames in the
vicinity of batteries. A catastrophic
explosion may occur.
Batteries can store significant amounts of electrical energy.
Do not use conductive equipment/tools around batteries. If
you cause an ARC, you can be severely injured. Remember,
there is no off switch on a battery!
52. If you must perform work around
batteries or battery racks, eye
wash/drench stations are required.
Spill kits for the electrolyte are to be
available. Use non-sparking/non-
conductive tools.
53. One of the most common occurrences with
electrical systems around the DOE complex
is excavating, cutting or drilling into
electrical systems.
There are many methods of trying to
identify buried or concealed electrical
conduits and cables. None of them are fool
proof.
Electrical System Intrusions
Facilities have developed methods and
procedures to help prevent these
occurrences.
If you are involved in this type of activity, it
is your responsibility to comply with facility
requirements.
54. If location or condition of energized
electrical systems is uncertain, utilize
electrically rated PPE and other protective
measures such as drill stops, hand digging,
vacuum excavators, etc.
Conduit cut – Location was right,
depth was wrong.

Signs, Symbols, Tags, and Barricades
are used to warn personnel of potential
electrical hazards.
OBEY ALL SIGNS AND BARRIERS!
56. REMEMBER!
The results of a mistake with electrical energy
occur at the speed of light. There is not time to
react after the error is made. You must think
ahead.
Pre-job briefs, planned work instructions, and
facility requirements are not optional. Pay
attention and obey all the rules, not just the
ones that are convenient. They provide the
edge you need to be safe with electrical energy.
Post-job reviews help keep us from repeating
errors – participate in them.
You are responsible for your safety.
57. Summary
It is very important to StartSafe and StaySafe around
electricity. In order to do so:
• Know the hazards
• Plan your work and plan for safety
• Avoid wet working conditions and other
dangers
• Avoid overhead power lines
• Use proper wiring and connectors
• Use and maintain tools properly
• Wear the correct PPE for the job
58. Summary
Many items concerning electrical safety have been
presented. It isn’t possible to cover all the hazards
electrical energy can present.
If you identify a hazard, make sure you and others are
safe and then report it immediately to the proper
authority for your work location.
70E requires electrical workers to be ALERT.
You are also required to be ALERT and AWARE of
potential electrical hazards. If you are not, you can be
severely injured or killed
Above all, BE SAFE.
