Primary Routes of Exposure:Inhalation, ingestion. Eye Contact:May cause slight to mild irritation of the eyes. Skin Contact:May cause slight to mild irritation of the skin. Dust may be irritating to the nose, mucous membranes and respiratory tract and cause chronic health Inhalation: problems. Ingestion:No information available on the physiological effects of ingestion. Acute Health Affects:May be irritating to skin, eyes and respiratory tract. Prolonged exposure to manganese containing dust may produce manganese pneumonitis and manganese Chronic Health Affects:poisoning. Symptoms include sleepiness, weakness and emotional disturbances. Equivocal studies have shown manganese may decrease fertility in men. NTP:No IARC:No OSHA:No SECTION 4: First Aid Measures Immediately flush the eyes with copious amounts of water for at least 10-15 minutes. A victim may need Eye Exposure: assistance in keeping their eye lids open. Get immediate medical attention. Wash the affected area with water. Remove contaminated clothes if necessary. Seek medical assistance if Skin Exposure: irritation persists. Remove the victim to fresh air. Closely monitor the victim for signs of respiratory problems, such as difficulty in Inhalation: breathing, coughing, wheezing or pain. In such cases seek immediate medical assistance. Seek medical attention immediately. Keep the victim calm. Give the victim water (only if conscious). Induce Ingestion: vomiting only if directed by medical personnel.
