In 1823, Samuel Brown patented the first internal combustion engine to be applied industrially. Father Eugenio Barsanti, was an Italian engineer, who together with Felice Matteucci of Florence invented the first real internal combustion engine in 1853.
Arc flash hazard as defined by the NFPA 70E: âa dangerous condition associated with the release of energy by an electric arcâ. Broken down to its components, we get: Arc: current flowing through air, caused either by human error or faulty equipment. Flash: release of energy including a bright flash of light. Hazard: the danger posed to personnel in the vicinity of the arc. Equipment and work methods are designed and used to separate personnel from live conducting parts by barriers and well-maintained equipment has a very low chance of spontaneously causing electric arcs. As such, arc flash incidents are rare.
Recently, the PCIC. safety committee recommended that arc Ëash. calculations be completed in conjunction with. short circuit calculations and protective device. coordination to help ensure that the most accu-. rate arc Ëash hazard results were achieved.
