An arc flash is a phenomenon where a flashover of electric current leaves its intended path and travels through the air from one conductor to another, or to ground. The results are often violent and when a human is in close proximity to the arc flash, serious injury and even death can occur.
Causes and consequences of arc flash are examined, with emphasis on historical data, real accidents, body burn and nonFR vs. FR clothing. Highlights include new HD Super Slo Motion video of arc flashes on real 480V equipment with clothed manikins in typical working positions, leading to a significant leap in understanding the arc flash hazard.

Understanding Embryo Grading. Embryo Grades Chances of Pregnancy. As embryologists, one of the most common questions that we get from patients is "What do the grades of my embryos tell us about my chances of becoming pregnant?" The answer to this question is not a simple one. ... Learn more about ARC's genetic testing partners and ...
Understanding the Different Types of Welding Services for Industrial Fabrication ... Shielded Metal Arc Welding (SMAW) ... An electrode holder holds the "stick" in place and an electric arc is created using either direct or alternating current. This in turn causes the electrode to slowly melt away while also melting the metals to be joined.
