Smiles. We have a biohazard training workshop on how to clean this stuff up. We have gloves, etc. in the room. It never happened to me but blood did--my own. I just know what was expected of us. Personally, I never thought twice about it. In my new workplace, not a school but an adult based special needs organization, I have had to clean up the vomit and we don't have a second crew that comes behind us.
