4.0 Properties, Storage, Health Hazards and Symptoms of Hydrogen Peroxide
4.1 Properties of hydrogen peroxide
4.1.1 General properties: Hydrogen peroxide is the scientific name of hydrogen peroxide, its aqueous solution is colorless and transparent, and has a weak special smell. Pure hydrogen peroxide is a light blue oily liquid. It is a strong oxidant with strong bleaching, antiseptic and bactericidal effects, especially in alkaline media.
4.1.2 Toxicity: Hydrogen peroxide is generally non-toxic, but has an irritating effect on the skin and mucous membranes of the eyes. Low concentrations can cause bleaching and burning sensations; high concentrations or prolonged exposure can cause epidermal blistering or severe eye damage; its vapors can irritate the lungs and even cause serious organ damage when they enter the respiratory system.
4.1.3 Combustibility: Hydrogen peroxide of any concentration is not flammable, but it is a strong oxidant. When metal ions, yeast, dust and other impurities are mixed in, especially when the concentration is high, it is easy to decompose and generate a large amount of oxygen, which is easy to cause the combustion of other combustible substances, and the combination of decomposition and oxidation during the ignition process. Prolonged exposure of hydrogen peroxide to combustibles can also cause combustibles to burn.
4.1.4 Explosives: Since the decomposition of hydrogen peroxide will release oxygen and heat, the higher the temperature and concentration, the faster the decomposition. Once the decomposition begins, the heat released by the decomposition will increase the temperature of the material, accelerate the decomposition of hydrogen peroxide, and generate more gas, which will expand as the temperature increases. At this time, if the container is closed, high pressure will be generated, causing the container to explode. Although hydrogen peroxide generally does not explode under normal pressure, the oxygen generated by its decomposition can form explosive mixtures with flammable vapors or gases under certain conditions. Once this mixture is triggered (such as sparks, static electricity, etc.), there is a danger of explosion. Hydrogen peroxide can also cause violent decomposition or even explosion in direct sunlight.
