HAZARDS IDENTIFICATION ****Emergency Overview**** Do not get in eyes, on skin or on clothing. Do not breathe vapors, dust or mist. Keep container closed. Use only with adequate ventilation. Wash thoroughly after handling. Avoid contact of large amounts of spilled material. Keep runoff out of soil and surface waterways. EC Classification(s): C-Corrosive, N-Harmful to the Environment EC Risk Phrases: R34: Causes burns R20/21: Harmful by inhalation and in contact with skin R41: Risk of serious damage to eyes R52/53: Harmful to aquatic organisms, may cause long-term adverse effects in the aquatic environment (See Section 15-REGULATORY INFORMATION for complete text of risk phrases.) Potential Acute Health Effects Eyes Very hazardous in case of eye contact (irritant, corrosive). Inflammation of the eye is characterized by redness, watering and itching. Exposure of the eyes to amine vapors may produce a temporary and reversible hazing or blurring of vision. Symptoms disappear soon after exposure is terminated. Respiratory Vapors produced though handling of this material in it’s uncured state may cause irritation of the eyes, nose, throat or other mucous membranes. Maintain adequate local exhaust or wear adequate personal protective equipment. Processing of cured materials may produce harmful and/or irritating dusts. Use of local exhaust and or dust/vapor respirators is recommended. Skin Hazardous in case of skin contact (corrosive). Skin contact may produce burns. Potential Chronic Health Effects Respiratory Repeated inhalation of vapors may cause lung damage. Provide appropriate ventilation to maintain exposures below occupational limits. Use of a filtering respirator rated for use with amines/ammonia is recommended where local ventilation is not adequate. See section 8-EXPOSURE CONTROLS/PERSONAL PROTECTION for exposure limits and recommended protective equipment. See section 11-TOXICOLOGICAL INFORMATION for further information. Skin Repeated skin contact may cause a persistent irritation or dermatitis. Repeated or prolonged exposure may aggravate existing dermatitis (skin contact). Overexposure to vapor, dust, or mist may aggravate existing respiratory conditions such as asthma, bronchitis, and inflammatory or fibrotic respiratory disease.
