Ok so regarding bases and "lye" or caustics.
Ive worked with them and gotten them on every part of me for the past 20 something years.
Safety glasses! there is little help regarding your eyes, flush with water for a full 15 minutes, full, 15 minutes.
on any skin, apply an acid, vinegar, windex, wine, beer. these all neutralize the base making it possible to rinse off. Follow with thorough soap and water wash.
and bases used properly are fine. the soap you will use has sodium hydroxide or potasium hydroxide in it, the same base.
Id imagine these warnings are based on spraying a food then eating it, the plant will work all of these sprays out in a few days. Grades are typically stated to back up purity/price and/or use at different levels ie schools vs. commercial labs.
