🤍 🤍 🤍 Cool Forgotten Weapons merch! 🤍 ArcFlash Labs has come out with a new coil gun design that takes the best elements of their underpowered EMG-01 and their overly bulky GR-1 Anvil and melded them into a much handier EMG-02. This new design maintains the same muzzle velocity as the Anvil (200-250 fps / 60-75 m/s) but uses smaller projectiles (5/16" armatures). It is far better handling, with the balance much improved by having a single large capacitor mounted at the rear and a battery directly under the grip. That battery is also now a commercial off-the-shelf rechargeable lithium-ion type. It's quite a lot of fun to shoot, and I am excited to see where this technology continues to develop!

An arc flash which is distinctly different from the arc blast, is part of an arc fault, a type of electrical explosion that results from a low-impedance connection to ground or another voltage phase in an electrical system.
🤍 🤍 Cool Forgotten Weapons merch! 🤍 The GR-1 "Anvil" is a portable, shoulder-fired gauss rifle made by Arcflash Labs. Yeah, it's pretty awesome to be living in the future where we actually have real gauss rifles, isn't it? First, some terminology. This is accurately identified as a gauss rifle, coil gun, or linear accelerator (although gauss "rifle" is a bit misleading, as it is a smoothbore launcher). It functions by using a series of coils energized to produce electromagnetic fields and pull a ferrous projectile down a barrel. Each coil accelerates the projectile faster, controlled by a series of optical gates that shut off a coil as the projectile passes beyond it. The GR-1 uses 8 coils, which use between 4000 and 16000 amps of electricity from 8 high voltage capacitors. These coils are able to accelerate a 1/2" in diameter steel dowel pin up to about 75 m/s (240 fps). The most novel technology in the GR-1 is the hardware which allows the standard lithium-ion battery (25V) to fully charge this bank of capacitors in approximately 3 seconds. Fundamentally, the GR-1 is an alpha sort of prototype. It is the equivalent to the first Wright Flyer - a technology demonstrator and a way to gain experience and expertise in building coil guns. As capacitor technology continues to improve, we will see coil gun capability improve from the level of airguns to that of handguns and eventually true rifles and beyond. Arcflash is leading the way in this technology, and I am grateful that they were willing to loan me one of their first batch of production guns for this filming! Legal details: The GR-1, and coil guns in general, are not federally regulated as firearms. Under the law, "firearms" are specifically defined as propelling a projectile by combustion, and coil guns do not do this. Arcflash treats their coil guns as airguns out of an abundance of legal caution, and as a result there are several places where the GR-1 is not shipped because of state or local regulation on muzzle energy of airguns.

Unknown location. This video emphasizes that when energized electrical equipment is in an abnormal condition there is a higher probability of an arcing fault and arc flash occurring. This worker should have used a Look, Listen & Smell simple philosophy. The worker did detect an abnormal condition at least three (3) times, but did not react appropriately. Had he reacted appropriately he would not have been exposed to an arc flash flash.
An Arc Flash event can expel Large amounts of deadly energy. The arc causes an ionization of the air, and arc flash Temperatures can reach as high as 35,000 degrees Fahrenheit. This is hotter than the surface of the sun” ينتج من خلال القوس الكهربى كمية حرارة كبيرة تصل الى آلاف الدرجات قادرة على إيذاء اى شخص قد تصل إليه وتحدث نتيجة تأين الهواء وتعتمد على بعد الشخص من مصدر القوس
🤍 🤍 Cool Forgotten Weapons merch! 🤍 The EMG-01B is a small portable rail gun made by Arcflash Labs. Introduced in 2017, it can throw magnetic dowel pins approximately 1/4" x 3/4" (6mm x 19mm) at about 150 fps (45m/s). It does this with a series of 8 capacitors and electromagnetic coils, and holds 18 projectiles in its magazines. Generating just under 5J of energy per shot, the EMG-01 is similar to a BB gun, and it was this lack of power that led to development of the GR-1 Anvil. Contact: Forgotten Weapons 6281 N.

🤍 🤍 Cool Forgotten Weapons merch! 🤍 David Wirth is one of the founders of Arcflash Labs, a small company developing "ultra-high energy pulsed power supplies", which have applications in a variety of fields - but today we are talking about electromagnetic weaponry. Arcflash is currently shipping out their first batch of commercial GR-1 "Anvil" shoulder-fired gauss rifles. They brought one down for me to try out, and I figured it would be best to start with some background discussion. So today, David and I are talking about how coil guns and rail guns work (and what the difference between the two is), how Arcflash came about developing the GR-1, where they expect the technology to go, and the applications for this and future mass accelerators. (For the record, I love being able to write a description like this and legitimately use terms like "rail gun" and "gauss rifle"...) So, check it out! And stick around for a detailed look at the GR-1 Anvil on Friday, and the lunacy of me taking it to a Backup Gun Match on Saturday... Contact: Forgotten Weapons 6281 N. Oracle 36270 Tucson, AZ 85740

Arc flash video illustrates consequences of not recognizing an increase in work task Risk Level. In 2010, the Panel Manufacturer personnel were carrying out the installation of a new energy meter and related wiring works in the incomer metering panel. Due to inadvertent touching of a neutral wire with the incoming live terminals, flashover occurred causing first-degree burn injuries to one person in the face and left hand. Root causes of the incident: - Risk Assessment for the project was not conducted. - Un-insulated tools were used. - Overconfidence of the worker, as similar jobs were done earlier in ten locations. Contact ESPS today to discuss your Electrical Safety Program and review your work task Risk Level Assessments.
An arc flash is dangerous and has the potential for causing serious injuries. It typically occurs suddenly and without warning - but not without a cause. Many arc flashes are caused by human error. The arc flash could have been avoided and the seriousness of arc flash injuries could have been reduced by those involved having followed proper procedures.

This video is based on Jim’s class “How to Perform an Arc Flash Study” 🤍 now updated with the NEW edition IEEE 1584. Also, watch Jim’s most current IEEE 1584 Major Changes video update 🤍 Arc flash studies should be simple. His approach is to perform the arc flash study “backwards” as he describes it. Select the PPE arc rating that is considered reasonable and then use the study results to verify the locations where the arc rating is sufficient. Jim uses the analogy of short circuit studies where the short circuit calculations are used to verify an interrupting rating. This same approach can be used for arc flash studies and is also discussed in his book: “Complete Guide to Arc Flash Hazard Calculation Studies,” click here for more details 🤍 Jim explains, when you’re performing an arc flash study, especially if this is one of the first arc flash studies that you’re undertaking, it’s really easy to get lost in all the data and in all the details. There’s just so much going on. But one of the things that you need to keep in mind– actually, to keep the focus on– is the primary objective of an arc flash study is simply to determine what level of PPE to wear. Whether you want to wear 8 calorie PPE, 8 calorie per square centimeter, or 12, or whatever your rating is. And a couple years ago, he wrote an article; basically, the premise of the article was to perform an arc flash study and perform it backwards. You might think, what do you mean by backwards? Well, what he means is determine what you want your answer to be first. And again, you might think that is kind of backwards. Your answer first? That doesn’t sound quite right. Well, actually, it makes sense. Because what happens is most people, companies and organizations, have an idea of what type of PPE, what rating, what arc rating of PPE they think is reasonable. And right now for most companies and most people, that would be 8 calorie or maybe 12 calorie per square centimeter for an arc rating. And so that’s actually your answer. And the arc flash study is really to support that answer. So as an example, let’s take a look at the results of this arc flash study. In this case, I’m showing the results. And we have the main switchgear, panel 1A, motor control center 1, and panel number 2. And really, what you’re doing in this case is you want to focus on the highest incident energies. And you actually want to look at all of the incident energies to make sure that they all are below the arc rating that you want to use. So in this case, if this group we’re going to be using, let’s say, 8 calorie per square centimeter as an arc rating for PPE, what this study did is it just confirmed that 8-calorie would be sufficient. I use the analogy of a short circuit study. Some of you have performed short circuit studies before. And it’s kind of similar. Because in a short circuit study, yes, you’re performing detailed calculations of the prospective short circuit current; but what you’re really doing is you’re comparing those currents against an interrupting rating that’s already in place or an interrupting rating that you want to use. So this is kind of the same thing as an arc flash study, what you’re really doing is performing the incident energy calculations to verify that the arc rating that you want to use is going to be sufficient.

NFPA 70E contains the requirements to perform a shock and arc flash hazard assessment, which involves a calculation performed by a professional engineer to determine the incident energy found at each location. This risk assessment determines the various arc flash boundaries, as well as the PPE that must be used when approaching each boundary. This information is taken from eSafety's Arc Flash Safety training course. 🤍
A common question and key component of electrical safety are understanding arc flash and how to protect against injury in an arc flash event. Arc flash happens when electricity flows through the air and causes a sudden release of energy. Arc Flash explosions take place in microseconds, hit with a ton of power, and can cause a multitude of injuries some that might surprise you when you think about electrical safety. Check out this video to learn more, and feel free to check out 🤍epsco.co or call 651-433-4550 for help with an Arc Flash Analysis or Electrical Safety Training.
An Arc Flash is an energy discharge of light and heat that forms when a fault occurs in an electrical circuit. The arcing results in a tremendous amount of energy being released as current flowing through ionized air. An Arc Blast, separate from an Arc Flash, is a supersonic shockwave produced when the uncontrolled arc vaporizes the metal conductors. Serious injury and fatality from when an arc flash/blast occur during open panel inspections. To mitigate the risk to workers, and the damage caused to assets, there are solutions you can implement for safer, more efficient, and cost-effective practices.
