SECTION 2: Hazards identification

OSHA Hazards Emergency Overview Color: Off-white Physical State: Powder Odor: Amine.

Signal word

CAUTION! Keep out of reach of children. May cause eye irritation. May be harmful if swallowed. Powdered material may form explosive dust-air mixture. Isolate area. Toxic fumes may be released in fire situations. Slipping hazard. Avoid temperatures above 80°C (176°F) _

Potential health effects

Eye Contact: May cause slight eye irritation. @(TM)* Trademark Page 1 of 10 Skin Contact: Brief contact may cause slight skin irritation with local redness. May cause more severe response if skin is abraded (scratched or cut). May cause more severe response if skin is damp. Skin Absorption: Prolonged skin contact is unlikely to result in absorption of harmful amounts. Skin Sensitization: For the minor component(s): Skin contact may cause an allergic skin reaction in a small proportion of individuals. Inhalation: No adverse effects are anticipated from single exposure to dust. For respiratory irritation and narcotic effects: No relevant data found. Ingestion: Low toxicity if swallowed. Small amounts swallowed incidentally as a result of normal handling operations are not likely to cause injury; however, swallowing larger amounts may cause injury.

Aspiration hazard

Based on physical properties, not likely to be an aspiration hazard Effects of Repeated Exposure The data presented are for the following material CTAC In animals, effects have been reported on the following organs after ingestion: Liver. High doses of sodium bicarbonate caused bladder effects in rats; however, repeated ingestion of sodium bicarbonate by humans has not resulted in known significant adverse effects.

Cancer information

Methylene chloride has been shown to increase the incidence of malignant tumors in mice and benign tumors in rats. Other animal studies, as well as several human epidemiology studies, failed to show a tumorigenic response. Methylene chloride is not believed to pose a measurable carcinogenic risk to man when handled as recommended. Studies have shown that tumors observed in mice are unique to that species. 1,3-Dichloropropene. Has been shown to cause cancer in laboratory animals by the oral route. Inhalation exposure resulted in an increase in the normal occurrence of benign lung tumors in male mice. Birth Defects/Developmental Effects: CTAC has caused birth defects in rats administered relatively high oral doses; no defects were observed at lower doses. CTAC did not cause birth defects or any other effects on the fetus when relatively high doses were administered dermally, the most likely route of exposure. The data presented are for the following material: Methylene chloride. Has been toxic to the fetus in laboratory animals at doses toxic to the mother.
