Livingstone Ear Plugs

Signal word

WARNING! Causes eye irritation. May cause allergic skin reaction. May cause allergic respiratory reaction. May be harmful if inhaled. Toxic fumes may be released in fire situations. May react with water. Elevated temperatures can cause hazardous polymerization. Material reacts slowly with water, releasing carbon dioxide which can cause pressure buildup and rupture of closed containers. Elevated temperatures accelerate this reaction. Isolate area. Keep upwind of spill. Stay out of low areas. Suspect cancer hazard. May cause cancer.

Potential health effects

Eye Contact Skin Contact Skin Absorption May cause moderate eye irritation. May cause moderate corneal injury. Prolonged contact may cause slight skin irritation with local redness. Prolonged skin contact is unlikely to result in absorption of harmful amounts. Skin Sensitisation Skin contact may cause an allergic skin reaction. Animal studies have shown that skin contact with isocyanates may play a role in respiratory sensitization. Inhalation Vapor concentrations are attainable which could be hazardous on single exposure. Excessive exposure to TDI may cause severe irritation of the upper respiratory tract and lungs, fluid in the lungs, permanent decrease of lung function, neurologic disorders, cholinesterase depression and gastrointestinal distress. Effects may be delayed. Respiratory Sensitisation May cause allergic respiratory response. Reexposure to extremely low isocyanate concentrations may cause allergic respiratory reactions in individuals already sensitized. Asthma-like symptoms may include coughing, difficult breathing and a feeling of tightness in the chest. Occasionally, breathing difficulties may be life threatening. 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. Swallowing may result in gastrointestinal irritation or ulceration.

Aspiration hazard

Based on physical properties, not likely to be an aspiration hazard.

Cancer information

An oral study in which high doses of TDI were reported to cause cancer in animals has been found to contain numerous deficiencies which compromise the validity of the study. TDI did not cause cancer in laboratory animals exposed by inhalation, the most likely route of exposure. Birth Defects/Developmental Effects TDI did not cause birth defects in laboratory animals. Slight effects were observed in the fetus but only at doses which caused toxic effects to the mother.
