Slaving in shifts

Here you can get some remarkable aural and visual impressions of “classic” occupational safety problems like intensely heavy labour, shift working and severe working conditions caused by heat, dust, noise and dangerous materials.


The steel furnace

This is our giant! The electric arc furnace built in 1955 has a capacity of 70 tonnes. It produced 15,000 tonnes of steel per month. Scrap iron was the starting material: it was smelted by electricity. The steel furnace was in operation at the Westphalia Mill in Dortmund till 1985. At DASA this eye-catcher symbolises everything we associate with the pressures of heavy shift work – an enormous amount of noise, huge amounts of dust and blistering heat.

The noise tunnel

Feel noise with all your senses. The tunnel gives you visual and aural impressions of what goes on in your ear canal. The decibel measurements give you an impression of how loud particular noises are. You can meet a few “rowdies” in our section on cultural history.

The rolling mill

The job of a rolling mill is to flatten steel.  Here you can see a so-called “trio mill” from the 1930s once used in the Geisweider Ironworks in Siegen. An expert explains how it works and talks about changes in industrial labour.

Did you know that…

….you yourself are an important source of heat? Even when a 40-year old, 1.70 metre tall, 70 kilo man is completely at rest he still produces 280 kilojoules an hour. Energy is measured in kilojoules. The warmth produced by muscular work has then to be added to the basal metabolism. Evaporating one litre of sweat releases around 2000 kilojoules into the immediate atmosphere.
