Just my opinion, but that’s not DCM residue on a needle, that’s someone using a needle to transfer and forcing DCM under their skin.

I drenched myself in DCM and stick myself with needles a few times.

Not to say the lab isn’t dangerous. I knew one person who peppered their abdomen with glass when a perchlorate exploded, scarred their face when a peroxide exploded and burned themselves with an organolithium.

But a simple needle stick with DCM residue won’t do that.
