Protect your lungs
This is an easy to watch ten-minutes PowerPoint presentation with Professor David Fishwick and Stonemason Terry. They are saying to you please take care of your precious lungs, at work, as every breath counts.
You can also do simple LOcHER hands-on practical experiments to help place their vital messages into your long-term memory to recall when you are working with hazardous substances at work.
Please read notes provided with slides to get good value from the presentation.
