I didn't really see the point of wearing goggles just to bleach my hair. I do if I am actually working on something in the lab (excluding harmless stuff that wouldn't do any damage if it did get in there), but a full SCBA mask/rebreather would be a bit....er...overkill, just to bleach my hair.
As for when I originally fucked my eye up...
I was knocking out a coupled of kilos of GHBNa salt from GBL. Only I didn't know about needing to use boiling stones at that age, I hadn't yet gone to secondary school and learned about that.
Adjusted my goggles to scratch my nose...would you fucking well believe it, thats the exact moment it chose to erupt.
That was NOT a fun night. Cleaning gamma-butyrolactone, caustic soda, and methanol off the walls, windows, ceiling, fridge....floor....you name it, it was there, eating away at the plastic/rubber fittings.
To this day I am still pretty surprised that A-nobody said anything, B-it didn't STINK (y-Butyrolactone smells filthy awful) and C-that the caustic/GBL mix didn't eat all the paint off the walls.
