though i’m not a chemist so take my words with a grain of salt -

google says the most dangerous bases can cause skin and eye damage, and be very flammable if they were to dissolve aluminium (two different chemicals). So I guess worst case scenario you open the windows, lock the room, and come back with protective equipment to clean up your mess

you probably wouldn’t handle something, that if dropped, would be dangerous enough to need a whole building evacuated outside of a dedicated room without wearing a full hazman suit and adhering to additional 100 precautions and safety measures

unless you’re the sort of guy to use a screwdriver to play with the demon core, but that’s not a liquid chemical base and hopefully won’t happen again
