Description of Driving Event:

Support contractor personnel contacted high voltage with a paint scraping knife while preparing a cable tray for painting in a facility / building transformer enclosure, causing a flash fire. Two of the worker¹s clothing caught fire and nearby combustibles were ignited. Two workers sustained burns to their hands and faces when one of the workers inserted the knife in a vent/drain slot. This accident did not result in permanent disability or death but the potential is evident.
