Please, use adequate ventilation (with a heat exchanger if you need to keep A/C in the room) if you’re going to be resin printing inside. I don’t want to see all of you guys get cancer from this hobby.

I’d love to have understood any of your funny words magic man… eli5?
Don’t breathe it; don’t get it on your skin and wear safety glases. Don’t flush it down the toilet.
Gloves: Those single-use gloves are spill protection and nothing more. If you can avoid touching resin avoid it and swap them immediately if they contact resin. Keep in mind that approx. 1-2 gloves per box (100 pcs.) can have holes/defects.
For waste treatment: Follow local guidance. As a rough rule of thumb: expose the resin to the sun (fully cure it), let the IPA evaporate and dispose it as a solid.
Flammable liquid storage: Keep the amount stored (inside) as small as possible. If the room is an escape route move your IPA washing station to a different room. Obviously, have a smoke detector in every room of your household, test them every few months and replace after 10 years.
How to check for contamination? Most printer resins are UV-reactive. Get a handheld UV-lamp/black light (those to check bank notes) and if anything lights up in green (fingerprints or spots) you have contaminated it with resin at some point (unless the object/material is also UV-reactive). Especially at the beginning, such a device is useful for learning good work practices (e.g. resin on the glove and touching the curing station or spills on the silicone matt around the washing station).
Any chemical is as safe as you make it: If you are careless it’s dangerous. You do your homework and it’s suddenly safe to use.
If you don’t feel safe or scared by a chemical don’t work with it. In this case ask around if somebody already does resin printing and get familiar with it before doing it on your own.
Honestly what worries me the most are the fumes
Is flushing it down the toilet going to cause fatbergs or worse?
No fatbergs, but it’s absolutely terrible for the environment in liquid form. If you need to dispose of resin, pour it into a pie tin or something and leave it out in sun for a day or two. After it’s solid, chuck it in the garbage.
Health and Safety says:
Don’t breathe in the fumes.
