SYSTEM Health: 3 Health: 3 Flammability: 1 Flammability: 1 Reactivity: 1 Reactivity: 1 Protection: B POTENTIAL HEALTH CONSIDERATIONS LIKELY ROUTES OF ENTRY: Inhalation; Contact; Absorption; Ingestion TARGET ORGANS: Skin; Nervous System; Respiratory Tract; Eyes; Lungs; Kidneys; Blood; Liver; Bladder; Page 2 0F 9 3. (Cont. } POTENTIAL IMMEDIATE EFFECTS FROM OVEREXPOSURE EYE CONTACT Can cause severe eye irritation, tearing and reddening, but not likely to permanently injure eye tissue. Temporary vision impairment (cloudy or blurred vision) is possible. SKIN CONTACT Corrosive to skin tissue, can cause chemical burns. Skin Sensitizer! Avoid exposure. If sensitized, repeated exposures will result in skin irritation, even at very low concentrations. SKIN ABSORBTION Toxic if absorbed through the skin causing systemic damage. TNHALATION Can cause severe respiratory irritation, dizziness, weakness, fatigue, nausea, headache and possible unconsciousness. Respiratory Sensitizer! Avoid exposure. If sensitized, repeated exposures will result in respiratory irritation and shortness of breath, even at very low concentrations. These asthma-type symptoms may develop immediately or be delayed up to several hours. INGESTION Irritating to mouth, throat, and stomach. Can cause abdominal discomfort, nausea, vomiting and diarrhea. Aspiration of material into the lungs can cause chemical pneumonitis which can be fatal. POTENTIAL LONG-TERM EFFECTS FROM OVEREXPOSURE:

Contains

a substance that is a possible cancer hazard based on human studies. No TARC cancer hazard information available. a substance which is classified by ACGIH as A2: Suspected human carcinogen. No NTP cancer hazard information available. No a substance that is a possible reproductive hazard based on tests with laboratory animals.

Additional information

HEALTH HAZARD Formaldehyde: Exposure to formaldehyde vapor at concentrations >1 ppm may cause Significant irritation of the eyes and respiratory tract. Irritation threshold is about 0.3 ppm. Formaldehyde was found to be weakly active in in vitro genotoxicity tests, but inactive in vivo. Lifetime inhalation of formaldehyde vapor at concentrations above 5 ppm for 6 hours/day caused nasal tumors in laboratory animals. Page 3 OF 9 3. (Cont. ) Tributyl phosphate: TBP was found not to be neurotoxic either acutely at 1000 mg/kg or after three months of exposure at up to 325 mg/kg/day. Assuming similar absorption of TBP by oral and inhalation routes of exposure and a breathing rate of approximately 170 mL/min, these values are approximately equivalent to inhalation exposures of 4900 mg/cu m acutely and 1590 mg/cu m per day subchronically. The ACGIH TLV (TWA) for TBP is 2.2 mg/cu m. This indicates that a minimum of a 700-fold safety factor exists for TBP as a potential neurotoxin(1). Large doses have been reported to cause dyspnea, weakness, pulmonary edema, and twitching in rats. Chronic inhalation of large doses can lead to general poisoning with paralysis, urinary bladder hyperplasia, and increased liver weight.(1) Healy, C.E.; Beyrouty, P.C.; and Broxup, B.R., Am. Ind. Hyg. Assoc 0. 56:349~-355 (1995). Tsobutyl alcohol: Administration by subcutaneous injection or by gavage has been reported to cause an increased incidence of benign and malignant tumors in rats. No human findings are available. MEDICAL CONDITIONS POTENTIALLY AGGRAVATED BY OVEREXPOSURE
