Did you see the link Tom D. posted that indicated that as much as 5% of bar oil ended up either in, or on, the operator?
Yes I did, Mike, and I feel that's significant. It is the primary reason I switched over and then the environmental benefits became more and more clear.
I concern myself with the health of my fellow treeguys.
Bar oil in or on you. That means a number of things. We know the oil sprays off in tiny, essentially invisible little atomized mist droplets. If the wind is wrong, it comes back at you, on the surface of your skin, in the air you breath, and on your clothes. Think about this the next time you wipe a light coating off the lenses of your safety glasses. Have you ever had a day where your lips feel like you put chap stick on them, but you haven't?
I don't know this for certain, but intuitively I believe most treeguys don't carry soap around and water to wash with. We handle the caps of our saws and get oil on our hands. Oil gets on our tools and we handle the tools and our hands are exposed. If we have oily hands and put them inside gloves, the inside of the gloves now have a residue that transfers back to our clean hands tomorrow morning. We maintain our bars and chains and our hands get oily. Oil on our hands is a reality in our job. It is daily repeated exposure. If we don't have the opportunity to wash, we have tainted hands all day.
I concern myself with Mr oily hands picking up a sandwich. And a good many of us smoke.... can you see how this repeated day after day exposure to bar oil and the NUMBER of different ways it can get on us or in us? This is just during our work hours, then you drag your filthy trousers in and throw em in the wash, possibly along with other clothes. We like to assume the clothes come out free of any oil residue, but do they really? Do we really know?
Just being aware of the ways the oil can get in us or on us is being personally responsible. None of us want ill repercussions years later after working our butts off so hard. Awareness is advised over ignorance. We do get exposed, it's almost impossible to avoid. I'd rather be exposed to veggie oil than crude bar- not that I claim veggie is OK to breath, but flat out common sense would say that crude bar would be the worse of the two.
Just food for thought.
