AEROFLOATO 242 Promoter MSDS: 0000308 Date: 07/01/2005 Page 2 of 7 <br />DANGER! CAUSES BURNS OF EYES AND SKIN <br />HARMFUL IF ABSORBED THROUGH SKIN OR SWALLOWED <br />POTENTIAL HEALTH EFFECTS <br />EFFECTS OF EXPOSURE: <br />The acute oral (rat) and acute dermal (rabbit) LD50 values for this material are estimated to be 0.25 ml/kg and <br />between 200 mg/kg and 1000 mg/kg, respectively. The estimated 4-hout inhalation (rat) value is >2,500 ppm. <br />Direct contact with this material may cause severe eye and skin irritation. Contact with acid may cause <br />liberation of hydrogen sulfide. Hydrogen sulfide has a strong rotten-egg odor, however, some people are <br />unable to smell the gas and exposure will deaden the sense of smell. Therefore, odor is an unreliable indicator <br />of exposure. Repeated or prolonged dermal contact with this material may cause severe allergic skin reactions. <br />Such allergic reactions may be incapacitating for an extended period of time. Overexposure to hydrogen sulfide <br />gas may cause severe eye or respiratory tract irritation, rapid development of coma and respiratory failure. Low <br />levels of hydrogen sulfide may cause headache, dizziness, staggering gait, neurological damage and gastritis. <br />Refer to Section 11 for toxicology 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 <br />by mouth to an unconscious person. <br />Skin Contact: <br />Take off immediately all contaminated clothing. Wear impermeable gloves. Wash immediately with plenty of water <br />and soap. Pay particular attention to skin crevices, nail folds, etc. Do not reuse contaminated clothing without <br />laundering. Do not reuse contaminated leatherware. <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. Obtain medical advice if there are persistent symptoms. <br />5. FIRE-FIGHTING MEASURES <br />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. <br />See 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 not known, wear approved, positive pressure, self-contained respirator. Where exposure <br />level is known, wear approved respirator suitable for level of exposure. In addition to the protective <br />clothing/equipment in Section 8, wear a two piece PVC suit with hood or PVC overalls with hood.
