hello, I'm a manicurist and I had recent nipped one of my customer on her toe cuticle, which it then bleeds. I used a piece of cotton ball with some drops of septic to stop the bleeding. After that I touched that cotton ball with my bare fingers, thumb and index, my skin was intact. After that I soaked her feet back in the water, after a few minutes or I took her feet out, the bleeding stopped, gave her a feet massage for a few more minutes. Finally, I cleaned her nail plates with acetone soaked cotton ball prior to put on the polish, then I felt irritated due to the acetone got on my finger and I realized that I got a little scratch, but no bleeding, on the back side of my thumb.
Note, there was never any contact between my scratch and her blood, or her wounded area, if there was any contact that would be between my scratch area and those cotton balls soaked acetone. Or, the contaminated water that got onto my fingers.
Did I expose to any risks?
