The document provides information about arc flash hazards, including definitions of arc flash and what can cause it. Arc flash results in the release of thermal heat up to 35,000 degrees Fahrenheit, toxic fumes, molten metal, and pressure waves, which can cause serious injuries like burns or death. The document discusses relevant standards like OSHA 1910, NEC 110.6, and NFPA 70E. It also covers shock and arc flash boundaries, personal protective equipment requirements according to hazard risk categories, and the steps to perform an arc flash analysis, including field verification, creating a single line diagram to model the system, performing the analysis, and integrating safety programs.
10 Most Common PPE Mistakes in Electrical Arc FlashMagid
The Top 10 Mistakes Made in Electrical Workplace Safety is a presentation from Magid Glove & Safety breaks down the 10 most common mistakes made in electrical workplace safety and provides safety tips and product recommendations that will help keep your workers safe and protected.
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.
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.

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.

Surge Protect, a critical issue you could not fail to know while implementing...Victor Lee
How high should we aim? Sparkovers (flashovers) which occur almost naturally in building wiring systems protect most equipment locations for surges above 6kV. So 6kV is the upper limit we should be concerned about. Note that poor or mediocre wiring insulation materials ironically help protect equipment better than excellent and expensive insulator materials.
There is increasing talk about “6kV surge protection”. We now realize why 6kV is being picked. However, we should keep in mind that so far such requirements are voluntary. But even if they do become mandatory, note that there are already designated “levels” of surge withstand capability: 2.5kV, 4kV, and 6kV, similar to CISPR 24. So it is probable that much like with CISPR 24/EN55024 we may only need to comply with a level lesser than max.
Five to 10 arc flash explosions occur in electric equipment every day in the United States. This number does not include cases in which the victim is sent to an ordinary hospital. Instead, these incidents are so severe the victims require treatment from a special burn center.

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.

A Strategic Approach: GenAI in EducationPeter 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.
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.

Editor's Notes
This is a presentation for all who want to re-enforce the basics of AFBefore we start have the audience present themselves and what company are they with?Ask the audience who is not familiar with what arc flash is?When did they hear about it?Arc flash analysis at their facilities?
You can also use a Coverall as a replacement for shirts and pants
The purpose of a short circuit analysis is to know what your maximem fault current is at bus.
S.C. is important to and AF analysis because it uses SC parameters (Voltage, Current, time, and distance) to calculate the incident energy angle.
