  • Welding Fumes and the effects of Manganese

    The potential risks of welding operations include the potential to breathe in metal fumes and toxic gases. Fume particles are formed from the vaporisation of molten metal that occurs during the process. These particles are very fine in size and may join together to form larger particles.. The biggest risk is exposure to the manganese contained in fumes that are given off during welding. ...

  • Nanotechnology – what is it? are there hazards?

    This is the first of a series articles on the emerging field of Nanotechnology. What is it? In short – small! Very small! Very, very small! Nanotechnology comes from the prefix Nano which, in English, means 1/billionth, just as micro means 1/millionth. So Nanotechnology involves 2 things: 1) extremely small man-made materials – some even as small as 1 atom thick, ...

  • If the fire doesn’t kill you, the CO2 might – carbon dioxide and fire suppression

    Carbon dioxide (CO2) has been used in fire extinguishers and fire suppression systems for more than a hundred years. In high concentrations it dilutes oxygen, thus removing one of the three elements of the combustion triangle (the other two being heat and fuel). It is also cheap, widely available, odourless, colourless, electrically non-conductive, chemically inert and it leaves no residue. It is ...
