Skin Remove contaminated clothing. Wash skin with soap and water. Obtain medical attention if discomfort persists. Inhalation Remove to fresh air. Obtain medical attention. Notes to physician There is no specific antidote. Treatment of overexposure should be directed at the control of symptoms and the clinical condition of the patient. 5. FIRE-FIGHTING MEASURES Flash point: 103 °C Flammable limits Lower limit: Not available Upper limit: Not available Hazardous combustion products Burning can produce the following combustion products: Oxides of carbon. Oxides of silicon. Carbon monoxide is highly toxic if inhaled; carbon dioxide in sufficient concentrations can act as an asphyxiant. Acute overexposure to the products of combustion may result in irritation of the respiratory tract. Special fire fighting procedures Do not direct a solid stream of water or foam into hot, burning pools: this may cause frothing and increase fire intensity. Special protective equipment for firefighters Self-contained breathing apparatus. Body covering protective clothing. Extinguishing media Suitable: Large fires: - alcohol-type foam or universal-type foams Small fires: - CO2 - dry chemical Unsuitable: None. Unusual fire and explosion hazards None known.

TOXICOLOGICAL INFORMATION SWALLOWING Acute effects May cause the following effects: - abdominal discomfort - nausea - vomiting May affect the gastrointestinal and respiratory systems, kidneys, liver, heart,|and cause severe CNS depression and death. Lung damage may result from accidental aspiration. Long-term oral exposure affected the brain, heart, liver, kidney, and bladder in laboratory animals. SKIN ABSORPTION Acute effects No evidence of harmful effects from available information. INHALATION Acute effects Short-term harmful health effects are not expected from vapor generated at ambient temperature. An ingredient in the controlled product has a major effect on the CNS, causing initial excitation (tremors, increased locomotor activity) followed by depression (incoordination, narcosis, anaesthesia). Acute exposure affects behaviour, performance, sleep cycle, the respiratory and cardiovascular systems and kidneys. An ingredient in the controlled product is a respiratory irritant, a CNS depressant and anaesthetic, causing headache, dizziness, acute behavioral effects (hilarity, irritability, confusion), impaired reaction time, poor coordination, visual disturbances, collapse, death as well as reversible kidney and liver damage.||Lethal cardiac irregularities may occur in predisposed individuals. Chronic exposure causes inflammation and degeneration of the respiratory lining, permanent hearing loss, behavioral changes and decreased learning and toxic changes in the optic nerve in experimental animals. CNS disturbances (headache, dizziness, abnormal gait, tremors, memory loss, incoordination), reduced dexterity, reduced ability to concentrate have been reported following long-term occupational exposure to an ingredient in the controlled product which may have involved simultaneous exposure to other solvents. An extensive review of available data suggests there may be peripheral nerve effects (paraesthesia, reduced conduction velocity), hearing

MATERIAL SAFETY DATA SHEET Revision: 1.0 2006.06.23 Page: 6 of 8 Product name: Niax® silicone L-540 damage and reversible liver and kidney damage, abnormal numbers of blood cells, but that no completely adequate studies are available. SKIN CONTACT Acute effects In experimental animals, an ingredient in the controlled product causes damage to the upper skin layers within 15 minutes, which may extend into the lower skin layers within an hour. May cause skin damage due to degreasing action. Prolonged contact may result in: - drying of the skin - defatting of the skin - development of fissures - dermatitis EYE CONTACT Acute effects Causes irritation. Causes the following effects: - stinging - discomfort - pain May cause the following effects: - excess redness of the conjunctivae - swelling of the conjunctivae Medical conditions aggravated by exposure A knowledge of the available toxicology information and of the physical and chemical properties of the material suggests that overexposure is unlikely to aggravate existing medical conditions. Other effects of exposure Solvents such as benzene and chlorinated hydrocarbons are toxicologically synergistic products in combination with an ingredient in the controlled product. SIGNIFICANT DATA WITH POSSIBLE RELEVANCE TO HUMAN HEALTH The following information is based on analogy with a similar material: This material was negative in a Salmonella Typhimurium/ Escherichia coli mutagenicity assay. Octamethylcyclotetrasiloxane: Repeated exposure to octamethylcyclotetrasiloxane by inhalation (300 ppm) or by the oral route in rodents produced increased liver weight, which was generally reversible after exposure ceased. Repeated exposure by inhalation in pregnant rats (700 ppm) did not produce any developmental effects, but certain reproductive parameters (reduction in mean live litter size, and implantation sites) were affected. The relevance of these data to humans is unclear. Further studies are on-going. Octamethylcyclotetrasiloxane was not clastogenic in an in-vivo bone marrow chromosomal assay in Sprague Dawley rats following inhalation of vapor. A 2 yr. combined chronic/carcinogenicity assay was conducted on octamethylcyclotetrasiloxane (D4). Fischer-344 rats were exposed by whole-body vapor inhalation 6 hrs/day, 5 days/week for up to 104 weeks to 0, 10, 30, 150 or 700 ppm of D4. A statistically significant increase in incidence of (uterine) endometrial cell hyperplasia and uterine adenomas (benign tumors) were observed in female rats at 700 ppm. Since these effects only occurred at 700 ppm, a level that greatly exceeds typical workplace or consumer exposure, it is unlikely that industrial, commercial or consumer uses of products containing D4 would result in a significant risk to humans.
