The other thing is cleaning dust from oneself with a compressor yep seen it done heaps of times even I have done it when young & unknowing.
Why not do it!
Simple it takes about 10 psi roughly to send the air into your body get some of that air in your bloodstream and presto air embolism and a pine box for you.
So if you see someone doing that stop them before they light switch themselves out of this life!
