Methylene Chloride

Methylene Chloride (Dichloromethane) works quite well as a paint remover but it's fairly toxic. It's metabolized to carbon monoxide for a start. It causes all the usual symptoms of any solvent and it's probably a carcinogen.

Sooooo, if you must use it, use excellent ventilation, wear gloves and especially use a mask with an organic vapour cartridge.
 
Use proper ventilation. My first job as a pharmaceutical manufacturing tech used a lot of MeCl2 in our process and our plumbing leaked and I was overcome. I barely made it outside and collapsed on the lawn.

It was always amazing to me how dense that stuff is. I'll never forget its smell.

Yep, too many painters and DIYers were getting CO poisoning from exposure to MeCl in enclosed spaces. People who were refinishing floors and tubs/showers were at the most risk.

It’s even banned for auto body and aviation use as well due to its hazards. Airbus, Boeing, Bombardier and Gulfstream didn’t like the stuff for paint removal on new commercial/private jets using more composite parts(and chlorinated solvents are a no-no on aluminum parts).
 
In my earlier day working as a model maker I used it a lot to melt plastic for prototype model . Much better than any glue, actually melted the plastic together as one.

My supervisor at the pharmaceutical company broke a 4L glass bottle of MeCl2 and thought he cleaned it up. Unbeknownst to him, it spilled into some lab drawers that contained plastic trays and plastic organizers. It was modern abstract art after the plastics melted and joined together.

Hmm we are still buying it for stripping aircraft, perhaps the manufacturers banned it internally?
