In the 1800s to 1900s, some ships could carry up to 500 people. That’s a lot of people that could arrive at the quarantine station without much notice. Station officers needed to have everything prepared at all times, and when a ship did arrive, they had a lot of work to do to make sure all their clothing and luggage was free from germs and bugs!
In 1903, a narrow-gauge tram rail was constructed that went the complete length of the jetty, and then all the way from the jetty to the Plague Hospital. After World War 2, the tram rail only went to the Dirty Luggage Block, located next to the Fumigation Block. The tramlines are still in place inside the fumigation shed.
The fumigation processed involved closing both doors and creating a vacuum to seal the doors. Each door weighs one tonne and took approximately 150 full turns of a heavy wheel for each door to be fully closed. The objects to be fumigated were exposed to 10 pounds pressure atmosphere, then they were either steamed (for smallpox), or subjected to a mixture of sodium cyanide (for bugs), methyl bromide (for poppy seeds) or formalin (for foot and mouth disease). The vacuum was then released, and the steam or gasses were vented through a pipe system at the back of the building.
Hot water for the shower block and laundry, and steam for fumigation, were both made by the steam generator. Originally powered by diesel fuel, there was a large underground fuel tank and a high chimney column that could be seen a long way off shore as a navigation landmark. Later, it was converted to run off electricity.
The steam generator is still located inside the fumigation shed.
