No such thing as a “freek accident of chemistry”. You mix the right chemicals and boom! Hydrogen peroxide has quite a safety record. The Meshershmit ME-163 used it as a propellant. At least one had a tank rupture and dissolved the pilot.
Could just have easily been the C-Stoff that dissolved the pilot, their nastiness mutually exceeded each other...
It’s used at about 20% concentration in some pool chemicals. Even at that strength it’s a powerful oxidizer and even a drop will cause a mild chemical burn that definitely stings. This is from my own direct, personal experience.
