Explosive strong oxidant. Hydrogen peroxide itself is not flammable, but it can react with combustibles to release a lot of heat and oxygen and cause fire and explosion. Hydrogen peroxide is most stable at pH 3.5 to 4.5, easily decomposed in alkaline solution, and can also decompose when exposed to strong light, especially short-wave radiation. When heated to above 100°C, it begins to decompose rapidly.
Industrial hydrogen peroxide is a strong oxidant, which can cause violent decomposition or even explosion under direct sunlight or mixed with impurities such as dust. In addition, long-term contact with flammable substances such as wood chips and fibers can cause spontaneous combustion.
Industrial hydrogen peroxide has bleaching and burning effects on the skin, and its steam can cause tearing and irritate the mucous membranes of the nose and throat.
It forms explosive mixtures with many organic substances such as sugar, starch, alcohols, petroleum products, etc., which can explode under the action of impact, heat or electric spark. When hydrogen peroxide comes into contact with many inorganic compounds or impurities, it will rapidly decompose and cause an explosion, releasing a large amount of heat, oxygen and water vapor.
Most heavy metals (such as copper, silver, lead, mercury, zinc, cobalt, nickel, chromium, manganese, etc.) and their oxides and salts are active catalysts, and dust, cigarette ash, carbon powder, rust, etc. can also accelerate the decomposition . Hydrogen peroxide at a concentration of more than 69%, in a closed container with an appropriate ignition source or temperature, will produce a gas-phase explosion.
Precautions:
1. It should not be taken orally, and it should be placed in a place that is not easily accessible by children.
2. Corrosive to metals, use with caution.
3. Avoid mixing with alkaline and oxidizing substances.
4. Avoid light and heat, and store at room temperature.
5. The validity period of medical treatment is generally 2 months.
6. Do not touch with hands
