Nope, but I made a very clean patch on the floor of the hospital during my training. They were using dilutish HCl to clean one of the instruments and I had to fill little containers with it. I spilled one all over my lab coat and on the floor. When I visit my friend in that lab, we reminisce about my first week there, spilling acid everywhere. Happy times.
Not burned myself. But yea once I have spilled few drops of concentrated H2SO4 on my new lab coat and till the time I left lab it was just a brown stain on the lab coat. After washing and drying there were so many tiny holes in my lab coat. That day I realized why its so important to wear lab coats. 🙂
