Victorian Institute of Occupational Safety and Health (VIOSH) Australia is the Asia-Pacific centre for teaching and research in occupational health and safety (OHS) and is known as one of Australia's leaders on the field. VIOSH has a global reputation for its innovative approach within the field of OHS management. VIOSH had its first intake of students in 1979. At that time the Institution was known as the Ballarat College of Advanced Education. In 1990 it became known as Ballarat University College, then in 1994 as University of Ballarat. It was 2014 that it became Federation University. VIOSH Australia students are safety managers, senior advisors and experienced OHS professionals. They come from all over Australia and industry. Students are taught active research and enquiry; rather than textbook learning and a one-size fits all approach. VIOSH accepts people into the Graduate Diploma of Occupational Hazard Management who have no undergraduate degree - on the basis of extensive work experience and knowledge.

Diver's Submarine Electric Torches were first developed to give illumination for close examination work. They have to be self-contained, the older ones are powered by an accumulator type battery which could be recharged. Some models were fitted with a switch to turn the light off saving on the battery power. The lens is of a convex type and magnifies the light. Sometimes there was a protective grill across the glass or prongs to protect the glass from an impact. When fully charged the battery would last about seven hours. Torches are made from non-ferrous metal so as not to corrode in their watery environment. Siebe Gorman & Co Ltd has been producing hand-held, battery-powered, submarine electric torches for divers and the Ministry of Defence (MOD) since the 1920s. In 1961, the famous diving manufacturer C.E. Heinke merged with Siebe Gorman, and for a short while, torches were made with the combined 'Siebe Heinke' inscription. However, this linked inscription was later dropped, with a return to the Siebe Gorman name tag. Date of manufacture for these torches can be determined by their Admiralty Pattern (AP) number that was used to identify a particular item and were for naval stores use. Before NATO stock coding became more widely used, earlier MOD torches often have a simple four-digit group of AP numbers such as AP4456 or AP4458. In 1975 Siebe Gorman moved from their Neptune Works at Chessington in Surrey to a new location at Cwmbran in Wales and by this time their manufacture of diving equipment had declined. (For additional historic company information on Siebe & Gorman see notes section this document.)The item is significant as it gives us a snapshot into marine history and the development of diving equipment generally, especially that used for salvage operations before and during WW2. The company that made the torch Siebe Gorman was a leading inventor, developer and innovator of marine equipment with its early developments in helmets, compressors and other diving equipment. Items that are today eagerly sought after for maritime collections around the world. The items that have been donated to the Flagstaff Hill collection give us an insight as to how divers operated and the dangers they faced doing a very necessary and dangerous job.Divers torch, brass with glass lens , screw on piece with three lugs attached.

Before the introduction of electricity, lighthouses had a clockwork mechanism that caused the lens to rotate with a light source inside that was either powered by Kerosene or Colza oil. The mechanism consisted of a large weight attached by a cable through the centre of the lighthouse to the top where the cable wrapped around a barrel, drum or wheels that controlled the speed of the lights rotation by a clockwork mechanism. The keeper would crank the clockwork mechanism, which would lift the weight ready for the next cycle similar to an old grandfather clock mechanism. Once the weight lifted to its apex at the bottom of the first landing, the keeper would let it fall, which would pull on the cable, which would, in turn, operate a series of gears activating the rotation of the Fresnel optical lens, which would then rotate to create the lighthouse’s unique light speed of rotation characteristic. Creating a specific characteristic required a way to regulate the speed of the rotation, and was important as sailors could identify a particular light by its speed and time between flashes. The weight had to fall at a certain rate to create the proper rotation speed of the lens and a regulator within the mechanism accomplished this. History: From 1851, Chance Brothers became a major lighthouse engineering company, producing optical components, machinery, and other equipment for lighthouses around the world. James Timmins Chance pioneered placing lighthouse lamps inside a cage surrounded by Fresnel lenses to increase the available light output these cages, are known as optics and they revolutionised lighthouse design. Another important innovation from Chance Brothers was the introduction of rotating optics, allowing adjacent lighthouses to be distinguished from each other by the number of times per revolution the light flashes. The noted English physicist and engineer, John Hopkins invented this system while employed at Chance Brothers. Chance Brothers and Company was a glass works and originally based in Spon Lane, Smethwick, West Midlands England. The company became a leading glass manufacturer and a pioneer of British glass making technology. The Chance family originated in Bromsgrove as farmers and craftsmen before setting up a business in Smethwick near Birmingham in 1824. They took advantage of the skilled workers, canals and many other industrial advances taking place in the West Midlands at the time. Robert Lucas Chance (1782–1865), known as 'Lucas', bought the British Crown Glass Company's works in Spon Lane in 1824. The company specialised in making crown window glass, the company ran into difficulty and its survival was guaranteed in 1832 by investment from Chance's brother, William (1788 – 1856). William owned an iron factoring business in Great Charles Street, Birmingham. After a previous partnership that Lucas had dissolved in 1836, Lucas and William Chance became partners in the business which was renamed, Chance Brothers and Company. Chance Brothers invented many innovative processes and became known as the greatest glass manufacturer in Britain. In 1848 under the supervision of Georges Bontemps, a French glass maker from Choosy-le-Roi, a new plant was set up to manufacture crown and flint glass for lighthouse optics, telescopes and cameras. Bontemps agreed to share his processes that up to then had been secret with the Chance Brothers and stayed in England to collaborate with them for six years. In 1900 a baronetcy was created for James Timmins Chance (1814–1902), a grandson of William Chance, who had started the family business in 1771 with his brother Robert. Roberts grandson, James became head of Chance Brothers until his retirement in 1889 when the company became a public company and its name changed to Chance Brothers & Co. Ltd. Additional information: Lighthouses are equipped with unique light characteristic or flashing pattern that sailors can use to identify specific lighthouses during the night. Lighthouses can achieve distinctive light characteristics in a few different ways. A lighthouse can flash, which is when brief periods of light interrupt longer moments of darkness. The light can occult, which is when brief periods of darkness interrupt longer moments of light. The light can be fixed, which is when the light never goes dark. A lighthouse can use a combination of flashing, oscillating, or being fixed in a variety of combinations and intervals to create individual light characteristics. It is a common misconception that a lighthouse's light source changes the intensity to create a light characteristic. The light source remains constant and the rotating Fresnel lens creates the various changes in appearance. Some Fresnel lenses have "bulls-eye" panels create beams of light that, when rotated between the light and the observer, make the light appear to flash. Conversely, some lenses have metal panels that, when rotated between the light and the observer, make the light appear to go dark. This Dioptric clockwork apparatus used to turn a lighthouse optical lens is very significant as it is integral to a lighthouses operation, we can also look at the social aspect of lighthouses as being traditionally rich with symbolism and conceptual meanings. Lighthouses illustrate social concepts such as danger, risk, adversity, challenge and vigilance but they also offers guidance, salvation and safety. The glowing lamp reminds sailors that security and home are well within reach, they also symbolize the way forward and help in navigating our way through rough waters not just on the oceans of the world but in our personal lives be it financial, personal, business or spiritual in nature. Nothing else speaks of safety and security in the face of adversity and challenge quite the way a lighthouse does.
