An accident occurred at the city power station at the King's Wharf this evening, four men, Messrs Alexander Wyllie (city engineer), W. M. Purcell (station superintendent), Henry Pearson (shift engineer) and William Albert Oram (greaser), being severely burned about the face and body. An explosion occurred in the crank chamber of the engine coupled with the generator, blowing off the lubricating cup. The oil shot out and, spreading fanwise, caught all four men. Oram and Pearson were removed to the hospital.
