Principle Routes of Exposure

Eye and skin contact, inhalation of vapors or mists, accidental ingestion. HUMAN EFFECTS AND SYMPTOMS OF OVEREXPOSURE: This product as a whole has not been tested. This hazard information is for the individual ingredients. ACUTE INHALATION..............: The sodium sulfite, sodium metabisulfite, EDTA, sodium tetraborate, hydroquinone and potassium carbonate in this product are expected to be irritating to the respiratory tract with symptoms of coughing, sore throat, and runny nose. Sodium sulfite and sodium metabisulfite may cause an allergic reaction in some asthmatics and sulfite sensitive individuals. Possible symptoms include bronchoconstriction, sweating, flushing, hives, rapid heart rate, decreased blood pressure, and anaphylaxis. Sodium hydroxide solutions are corrosive and its vapors are irritating to the mucous membranes of the respiratory tract. Inhalation of vapors results in coughing, choking and inflammation of the respiratory tract. The irritating nature of these vapors is typically sufficient to cause a person to leave areas of excessive concentration. 250 mg/m3 is immediately dangerous to life or health. CHRONIC INHALATION............: Persons who have been previously sensitized to sulfites should take precautions to prevent the inhalation of sodium sulfite. Prolonged exposure to high concentrations of sodium hydroxide may cause discomfort and ulceration of the nasal passages. ACUTE SKIN CONTACT............: Sodium sulfite, sodium metabisulfite, EDTA, sodium tetraborate, and hydroquinone can be irritating to the skin with symptoms of reddening, itching, and swelling. Potassium carbonate can be severely irritating with symptoms of reddening, itching, swelling, and possible burns. Hydroquinone may cause skin sensitization with symptoms of rash, itching, hives, and swelling. Direct contact with high concentrations of sodium hydroxide causes burns unless the product is washed off (alkalies penetrate the skin slowly). CHRONIC SKIN CONTACT..........: Repeated contact with low concentrations of sodium hydroxide may cause skin drying and ulcerations. ACUTE EYE CONTACT.............: Sodium sulfite, sodium metabisulfite, EDTA, sodium tetraborate, and hydroquinone can be irritating to the eyes with symptoms of tearing, stinging, reddening, and swelling. Potassium carbonate can be severely irritating with possible burns. Sodium hydroxide solutions are corrosive and are irritating to the mucous membranes of the eyes. Severe eye irritation will result from exposure to the solution. Initial symptoms may be discomfort, tearing and/or blurring of vision. Permanent eye damage including blindness may result if there is a delay in flushing it from the person's eyes. CHRONIC EYE CONTACT...........: Repeated exposure to hydroquinone may cause intolerance of the eyes to light. In addition, repeated overexposure to hydroquinone may cause pigment deposition, which can extend into the cornea with continued exposure to high concentrations. This pigment deposition does not impair vision. Repeated or prolonged exposure to sodium hydroxide may result in lacrimation and chronic conjunctivitis. ACUTE INGESTION...............: Ingestion of this product may cause gastrointestinal irritation. Hydroquinone may be harmful if swallowed with symptoms including nausea, vomiting, drowsiness, dizziness, disorientation, bluish skin color, and stomach pain. If ingested, sodium hydroxide solutions are corrosive to the tissues with which it comes in contact. Ingestion may cause burning pain in the mouth, throat, esophagus and abdomen. OTHER EFFECTS OF EXPOSURE.....: See Section 11. CARCINOGENICITY...............: The components of this product are not listed by NTP, IARC or regulated as a carcinogen by OSHA. MEDICAL CONDITIONS AGGRAVATED BY EXPOSURE......: Persons with preexisting eye, skin, liver, or kidney conditions or impaired pulmonary function may be more susceptible to the effects of this product.
