Potassium hydroxide has a burning effect on tissues, which can dissolve proteins and form alkaline denatured proteins. The solution or dust splashed on the skin, especially on the mucous membrane, resulting in soft scabs. The higher the solution concentration is, the higher the temperature is, the stronger the effect is. Splashing into the eye can not only damage the cornea, but also damage the deep tissue of the eye.
The highest allowable concentration was 0.5 mg/m. The work should be to prevent the touched the skin and eyes, if accidentally touched, damaged parts available water washing, then wet compress 5% acetic acid, tartaric acid, hydrochloric acid or citric acid solution; such as the human eye splash, used water or saline carefully slowly washed 10 ~ 30 min, and then into 2% or 0.5% of the novocaine ropivacaine solution. When the operation should be made of sturdy cloth overalls, wearing rubber gloves, sleeves, aprons, rubber shoes and other labor supplies, hands should be coated with neutral and hydrophobic ointment.
Potassium hydroxide safety measures: skin contact: immediately remove contaminated clothing, rinse with a large number of flowing water for at least 15 minutes. Medical treatment.
Eye contact: lift eyelids immediately and rinse thoroughly with plenty of flowing water or saline for at least 15 minutes. Medical treatment.
Inhalation: quickly escape from the scene to the fresh air. Keep airway unobstructed. If breathing is difficult, give oxygen. If respiration stops, immediate artificial respiration is performed. Medical treatment.
Ingestion: gargle with water, drink milk or egg white. Medical treatment.
Fire extinguishing method: use water and sand to save, but must prevent the product from water splash and cause burns.
Potassium hydroxide for use and use
Inorganic industrial used for production of potassium salt, such as Potassium Permanganate, potassium nitrite, two potassium hydrogen phosphate and other raw materials. The chemical industry used to make soap, soap, and potassium Wash Shampoo soft soap, cream, cream, shampoo and other raw materials. The pharmaceutical industry is used to make progesterone, vanillin and other raw materials. The dye industry is used to make melamine dyes.
Battery industry is used to make alkaline batteries. Used as a desiccant, sorbent, used for preparing potassium soap, oxalic acid and various salt, also used in electroplating, engraving, lithography, etc.; potassium is mainly used for the production of raw materials, such as Potassium Permanganate, potassium carbonate, etc.. In the pharmaceutical industry, for the production of potassium borohydride, spironolactone, batyl alcohol, progesterone and testosterone propionate. For the production of potassium soap, alkaline battery, cosmetics in light industry (such as cream, cream and shampoo).
