Groucho,
where I work, we burn about 150,000 litres of diesel just to get the boilers lit and running them on coal. 8 units, 2-3 times each per year.
We've got a corporate innovation system going, and have o do all sorts of presentations to go and convince management that we are thinking.
So I opened this presentation by handing the audience an MSDS, and told them to read it carefully before handling the sample bottle that I was about to send around the room.
Should have seen the fear in their eyes as I handed out a bottle of Rapreseed Ethyl Ester (glycerine not removed), that I prepared in my own kitchen.
Finally, one or two READ the MSDS, and were amazed to find that table salt is twice as toxic as the stuff they were handling.
