Scary stuff?
would you use this stuff? remembering that we use it at concentrations of around 150,000 ppm "in concentrations of as low as 0.2 ppm. Coughing and vomiting may occur at 30 ppm and lung damage at 60 ppm. About 1000 ppm can be fatal after a few deep breaths of the gas.[3] Breathing lower concentrations can aggravate the respiratory system, and exposure to the gas can irritate the eyes.[34] The toxicity comes from its oxidizing power. When inhaled at concentrations above 30 ppm, it begins to react with water and cells, which change it into hydrochloric acid (HCl) and hypochlorous acid (HClO).

When used at specified levels for water disinfection, the reaction of chlorine with water is not a major concern for human health. However, other materials present in the water may generate disinfection by-products that can damage human health.[35][36]
yep good old SH (chlorine)

If I had a choice between SH and peroxide I personally would chose peroxide, but I don't have a choice! and peroxide is never used at 70% concentration except for extreme industrial uses, 10% to 30% in the usual concentrations

My point is, every thing that we are all using right now today can be harmful to us, be careful and smart and think about what we are handling
