SECTION 3: Hazards Identification
Emergency Overview:	Irritating to skin, eyes and respiratory tract.
Primary Routes of Exposure:	Contact with skin and eyes. Dust inhalation.
Eye Contact:	Dust, if present, may cause mild to moderate irritation of the eyes.
Skin Contact:	Direct contact with metal, or dust, if present, causes mild irritation of the skin.
Inhalation:	Inhalation of any fine dust present is irritating to the nasal cavity, mucous membranes and respiratory tract.
Ingestion:	No specific information is available on the physiological effects of ingestion.
Acute Health Effects:	Dust, if present, is irritating to skin, eyes and respiratory tract. Moderately caustic alkaline surface oxides may irritate the skin.
Chronic Health Effects:	No information available on long-term chronic effects. Impurities in some mineral oils may be tumorigens.
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 10-15 minutes. A victim may need assistance in keeping their eye lids open. Get immediate medical attention.
Skin Exposure:	Wash the affected area with water for at least 15 minutes. Remove contaminated clothes if necessary. Seek medical assistance if irritation persists.
Inhalation:	(For dust or fume) Remove the victim to fresh air. Closely monitor the victim for signs of respiratory problems, such as difficulty in breathing or coughing. In such cases seek immediate medical assistance.
Ingestion:	Seek medical attention immediately. Keep the victim calm. Give the victim water (only if conscious). Induce vomiting only if directed by medical personnel.
