Composition/Information on Ingredients <br />Components/ Materials CAS Number % <br />Hydroquinone 123-31-9 5 <br />Sodium Hydroxide 1310-73-2 3 <br />Sodium Sulfite 7757-83-7 11 <br /> <br />Hydroquinone is subject to the reporting requirements of section 313 of SARA 313 Title III (40CFR part 372) <br /> <br />4. First Aid Measures <br />Inhalation No specific intervention is indicated as the product is not likely to be hazardous by inhalation. <br />Skin Contact Flush skin with water after contact. Wash contaminated clothing before reuse. <br />Eye Contact In case of contact, immediately flush eyes with plenty of water for at least 15 minutes. Call a <br />physician. <br />Ingestion Only induce vomiting at the instruction of medical personnel. Call a physician or poison control <br />center immediately. Never give anything by mouth to an unconscious person. <br />Treatment note to <br />physician <br />Absorption of hydroquinone into the body leads to the formation of methemoglobin that, in <br />sufficient concentration, causes cyanosis. Since reversion of methemoglobin to hemoglobin <br />occurs spontaneously after termination of exposure, moderate degrees of cyanosis need to be <br />treated only by supportive measures such as bed rest and oxygen inhalation. Thorough <br />cleansing of the entire contaminated area of the body, including scalp and nails, is of utmost <br />importance. If cyanosis is severe, intravenous injection of methylene blue, one milligram per <br />kilogram of body weight, may be of value. <br /> <br />5. Fire Fighting Measures <br />Flammable Properties Flash point non-flammable <br />Flammable Limits <br /> Lower <br />Flammable <br />Limit <br />Not applicable <br /> Upper <br />Flammable <br />Limit <br />Not applicable <br />Hazardous <br />Combustion Products <br />Carbon monoxide <br />Unusual <br />Fire/Explosion <br />Hazards <br />None <br />Extinguishing Media Use that of surrounding fire <br />Special Firefighting <br />Procedures <br />Wear self-contained breathing apparatus & protective clothing to prevent contact with skin and <br />eyes. <br /> <br />6. Accidental Release Measures <br />Small Spill Absorb spill with an inert material and place in a chemical waste container <br />Large Spill Contain spilled liquid with sand or earth. Absorb spill with an inert material and shovel <br />into a chemical waste container. Prevent runoff from entering into storm sewers and <br />ditches which lead into natural waterways <br /> <br />7. Handling and Storage <br />Handling Avoid contact with eyes. Keep container closed. Use only in a well ventilated area. <br />Wash thoroughly after handling. Avoid prolonged or repeated breathing of mists and <br />vapors. Avoid prolonged or repeated contact with skin. <br />Storage Store between 65-95ºF, preferably between 68-85ºF, in order to avoid decomposition <br />or crystallization. Keep containers sealed when not in use. <br /> <br />8.
