SECTION 3: Hazards Identification
Emergency Overview: Very toxic by inhalation and if swallowed. Inhalation can lead to headaches and dizziness. Prolonged exposure can lead to convulsions and coma.
Primary Routes of Exposure: Ingestion, inhalation
Eye Contact: May cause mild irritation to the eyes.
Skin Contact: May cause mild irritation to the skin.
Inhalation: Very toxic by inhalation. Inhalation could lead to dizziness and headache.
Ingestion: Very toxic if swallowed.
Acute Health Effects: Very toxic by inhalation and if swallowed. Inhalation could lead to headache and dizziness.
Chronic Health Effects: Prolonged exposure to manganese containing dust may produce manganese pneumonitis and manganese 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
Eye Exposure: Immediately flush the eyes with copious amounts of water for at least 15 minutes. A victim will need assistance in keeping their eye lids open. Get immediate medical attention.
Skin Exposure: Wash the affected area immediately with water. Remove contaminated clothing if necessary. Seek medical assistance if irritation persists.
Inhalation: Remove victim to fresh air immediately. Keep the victim lying down and warm. Give oxygen as soon as possible. If shock occurs, respond with appropriate first aid. Transport the victim to a hospital.
Ingestion: Seek medical attention immediately. Keep the victim calm. Give water to dilute the toxin (only if conscious). Induce vomiting only if directed by medical personnel.
SECTION 5: Fire Fighting Measures
