Historical information

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.

Dust explosions are the result of high concentrations of combustible dust particles rapidly combusting inside an enclosed space. When mixed with oxygen these fine particles can ignite when in contact with a spark, metal ember, cigarette butt or other source.

Electrical Engineering lecturer Graeme Hood remembers Paul Brass demonstrating this unit to show how dangerous a combination of dust and electricity it. The demonstration would take about 1 minute, and would culminate with a loud bang which would make everyone jump. This item was probably last used by Paul Brass.
