The  incident took place as utility  personnel were concluding their hour-long high-voltage safety demonstration that was presented to city police, firefighters, office staff and public works personnel. The injured worker was disconnecting wires from a power source when the arc flash occurred.  His helmet was blackened on one side and his safety gloves were still on.  He sustained second degree burns on the left side of his face and was taken to the hospital as a precaution.  The employee was wearing arc flash clothing and the article said all required “PPE which minimized the injuries from the arc flash” but no faceshield was required by this company.  OSHA has required eye or face protection since 1991 for arc exposures.  The new NESC would likely require about 20 cal/cm² protection for this type of job but still does not mention face protection, only clothing.
