Health hazards

CORROSIVE. CAUSES SEVERE SKIN BURNS AND EYE DAMAGE. HARMFUL IF SWALLOWED.

Physical hazards

MAY BE CORROSIVE TO METALS. Mixing with water, acid or incompatible materials may cause splattering and release of heat. Do not store in aluminum container, use aluminum fittings, or aluminum transfer lines, as aluminum will quickly corrode and flammable hydrogen gas will be generated. Absorb spillage to prevent material damage. AQUATIC TOXICITY: HARMFUL TO AQUATIC LIFE. Category 1 - Corrosive to metals GHS: CONTACT HAZARD - SKIN Category 1B - Causes severe skin burns and eye damage GHS: CONTACT HAZARD - EYE Category 1 - Causes serious eye damage GHS: ACUTE TOXICITY - ORAL Category 4 - Harmful if swallowed HAZARDS NOT OTHERWISE CLASSIFIED (HNOC) HARMFUL TO AQUATIC LIFE Unknown Acute Dermal Toxicity There is no acute dermal toxicity data available for this material. Potassium hydroxide is a corrosive substance at concentrations of about 2% and higher. For this reason, there is no need for further acute toxicity testing Unknown Acute Inhalation Toxicity There is no acute inhalation toxicity data available for this material. Potassium hydroxide is a corrosive substance at concentrations of about 2% and higher. For this reason, there is no need for further acute toxicity testing GHS SYMBOL: Corrosive, Exclamation mark GHS SIGNAL WORD: DANGER GHS HAZARD STATEMENTS GHS - Physical Hazard Statement(s) May be corrosive to metals GHS - Health Hazard Statement(s) Causes severe skin burns and eye damage Causes serious eye damage Harmful if swallowed GHS - Precautionary Statement(s) - Prevention Do not breathe mist, vapors, or spray Wash skin and contaminated clothing thoroughly after handling Do not eat, drink or smoke when using this product Wear protective gloves/protective clothing/eye protection/face protection Keep only in original container Avoid release to the environment GHS - Precautionary Statement(s) - Response IF SWALLOWED: Rinse mouth.
