Some large hospitals have an incinerator on-site, which is used to burn medical waste and small body parts. I don't recall there being one at Mt. Sinai but it's possible. Burning entire bodies is almost always done at a crematorium, where the ovens are large enough to accommodate a casket.
Definitely Betadine. I had a minor surgery done on my foot about two weeks ago and they used Betadine to disinfect the surgical area and get this, it had the consistency of syrup. It, however, does not have a distinct smell, nor does it some off of ANYTHING easily. It took almost twenty minutes in the shower (when I could shower) to scrub that stuff off once it dried.
This is such an interesting photo! The building is being demolished right now so I was curious about the history of it. Would have never known they had something cool instead.
I doubt it's rust water . . . I've never known rust suspended in water to be have the consistancy of syrup. That foot print looks like the result of some viscous liquid. The print is too crisp for just plain rusty water in my opinion.
Many of people died of violent crimes in this hospital, as a resident of south Philly not in this neighborhood but in the early 90's the area had alot of violence from drug wars and the mob wars and this hospital was on the news every night with a saying like " victim was shot and taken to mount Sinai and pronounced dead" it was normal in those days. This was a busy emergency room.
I have to agree with various others, looks like betadine to me too. However it still could be rust water. I would think something like betadine getting watery, thick, and ugh stale(?) would smell very unique.
I remember that song!
