Arc flares are usually caused by faults when working in the switchgear, contaminants, foreign objects such as forgotten tools or animals entering the device. This means that even the most modern switchgear is at risk.
In the event of an arc failure, a tremendous amount of energy is released in milliseconds. Everyone close to the switchgear at that time is in great danger. Excessive temperatures, toxin combustion residues and explosive pressure waves are the greatest danger.
