The explosive nature of an electric arc has been documented in a number of case studies. The intense heat from an arc flash causes sudden expansion of air resulting in a blast and the associated pressure waves and the resulting explosions rival that of explosive substances. Energies produced by arc flash explosions have been known to propel large objects such as switchboard doors, bus bars and personnel several metres at very high speeds. As an example of an arc blast, a 50kA arcing fault will produce a pressure of approximately 10 kPa, 1 metre from the arc location.
