Dr. Ozorio was a witness of the appalling typhoon in 1906. He was an enthusiastic race-goer and was present at the catastrophe on the Happy Valley Racecourse in 1918. He engaged in first-aid work for those who were rescued from the flames. He was also present at the burning of the steamer "Hankow" at the Canton Steamer Wharf when some hundreds of people perished.
