AEROFLOAT® 208 Promoter, Aqueous MSDS: 0000414 Print Date: 01/10/2008 Page 2 of 7 <br />EFFECTS OF EXPOSURE: <br />The acute oral (rat) LD50 and dermal (rabbit) LD50 values are 8,460 mg/kg and 5,600 mg/kg, respectively. Direct <br />contact with this material may cause eye and skin burns. Contact with acid may cause liberation of hydrogen <br />sulfide. Hydrogen sulfide has a strong rotten-egg odor, however, some people are unable to smell the gas and <br />exposure will deaden the sense of smell. Therefore, odor is an unreliable indicator of exposure. Repeated or <br />prolonged dermal contact with this material may cause severe allergic skin reactions. Such allergic reactions may <br />be incapacitating for an extended period of time. Overexposure to hydrogen sulfide gas may cause severe eye or <br />respiratory tract irritation, rapid development of coma and respiratory failure. Low levels of hydrogen sulfide may <br />cause headache, dizziness, staggering gait, neurological damage and gastritis. Refer to Section 11 for toxicology <br />information on the regulated components of this product. <br />4. FIRST AID MEASURES <br />Ingestion: <br />If swallowed, call a physician immediately. Only induce vomiting at the instruction of a physician. Never give anything by <br />mouth to an unconscious person. <br />Skin Contact: <br />Remove contaminated clothing and shoes without delay. Wear impermeable gloves. Wash immediately with plenty of <br />water and soap. Pay particular attention to skin crevices, nail folds, etc. Do not reuse contaminated clothing without <br />laundering. Do not reuse contaminated leatherware. Obtain medical attention. <br />Eye Contact: <br />Rinse immediately with plenty of water for at least 15 minutes. Obtain medical attention immediately. <br />Inhalation: <br />Remove to fresh air. If breathing is difficult, give oxygen. Apply artificial respiration if patient is not breathing. Obtain <br />• medical attention immediately. <br />5. FIRE-FIGHTING MEASURES <br />Suitable Extinguishing Media: <br />Use water spray or fog, carbon dioxide or dry chemical. <br />Protective Equipment: <br />Firefighters, and others exposed, wear self-contained breathing apparatus. Wear full firefighting protective clothing. See <br />MSDS Section 8 (Exposure Controls/Personal Protection). <br />Special Hazards: <br />Sulfur dioxide or hydrogen sulfide may be formed under fire conditions. Do not flush to sewer which may contain acid. <br />This could result in generation of toxic and explosive hydrogen sulfide gas. <br />6. ACCIDENTAL RELEASE MEASURES <br />Personal precautions: <br />Where exposure level is known, wear approved respirator suitable for level of exposure. Where exposure level is not <br />known, wear approved, positive pressure, self-contained respirator. In addition to the protective clothing/equipment in <br />Section 8 (Exposure Controls/Personal Protection), wear impermeable boots. <br />Methods For Cleaning Up: <br />Cover spills with some inert absorbent material; sweep up and place in a waste disposal container. Flush spill area with <br />• water.
