Skin Skin absorption hazard. Mildly irritating to the skin but not a skin sensitizer. Inhalation Signs of respiratory tract irritation (such as nasal discharge and difficulty breathing) may occur after exposure to aerosol or high vapor concentrations. Eye Moderate to severe eye irritant. Excess redness of the conjunctiva may occur. Permanent corneal damage is not expected. Ingestion Ingestion may cause discomfort and irritation of the gastrointestinal tract, dizziness and shortness of breath. Repeated inhalation exposure may cause reversible irritation at the site of initial contact, and transient CNS effects have also been observed. NMP produced liver tumors and kidney effects in test animals. The relevance of these findings to humans is unknown. NMP may adversely affect reproduction in the rat after ingestion, although fertility is unaltered. The relevance of these findings to humans is unknown. Fetal effects were seen in pregnant animals exposed to NMP by ingestion, inhalation and skin contact. The relevance of these findings to humans is unknown. |
