A simple investigation experiment looking at the pH of blood at a Tasmanian high school has turned into a biohazard scare after teacher somehow thought sharing needles would be totally fine for adolescent boys. In some muddled form of defence the teacher did “attempt to sterilise the needle with methylated spirits between tests.” (Methylated spirits its not really suitable for sterilizing).
Pretty much any official is saying that this was a major balls up by the teacher, and I’m finding hard to believe that with all the red tape (in the for of occupational health and safety) present in Australian workplaces these days, that this investigation was ever approved. I have no problem with hands on experiments. In fact, I think these should be encouraged. On top of that, if we expect to have smart and scientifically literate graduates from high school, experiments involving potential biohazards should be allowed. However (or even because of that) it still very important to recognise that risks are involved and the appropriate precautions be taken.
Do read the comments on The Mercury article too.
There seems to be some sections of the world who are somehow thinking that the teacher has not done anything wrong, because there are no schoolboys in Tasmania with bloodborne infectious disease. Perhaps they could do well to investigate the Health and Ageing website which show that historically (prior to vaccinations) they have been one of the highest risk groups for Hepatitis (which is probably the largest worry in this instance, rather than HIV). Blood-borne transmission is probably the number one risk that health organisations try to minimize to prevent the spread of disease.
