Section 3 - Hazards Identification

Appearance: white with a blue, gray or red hue solid.
Caution! May cause eye, skin, and respiratory tract irritation.
Target Organs: None.


Potential Health Effects
Eye: Causes eye irritation. May cause conjunctivitis.
Skin: Causes skin irritation. Chronic exposure has been linked with rhinitis (inflammation of the mucous membrane of the nose), nosebleeds, laryngitis, pharyngitis, lung membrane effects, and an impaired sense of smell and taste.
Ingestion: Ingestion of large amounts may cause gastrointestinal irritation. May cause mechanical obstruction of the digestive
Inhalation: Dust is irritating to the respiratory tract.
Chronic: Chronic exposure has been linked with rhinitis (inflammation of the mucous membrane of the nose), nosebleeds, laryngitis, pharyngitis, lung membrane effects, and an impaired sense of smell and taste.

Section 4 - First Aid Measures

Eyes: Flush eyes with plenty of water for at least 15 minutes, occasionally lifting the upper and lower eyelids. Get medical aid.
Skin: Flush skin with plenty of water for at least 15 minutes while removing contaminated clothing and shoes. Get medical aid if irritation develops or persists.
Ingestion: If victim is conscious and alert, give 2-4 cupfuls of milk or water. Get medical aid.
Inhalation: Remove from exposure and move to fresh air immediately. Get medical aid if cough or other symptoms appear.
Notes to Physician: Treat symptomatically and supportively.

Section 5 - Fire Fighting Measures

General Information: As in any fire, wear a self-contained breathing apparatus in pressure-demand, MSHA/NIOSH (approved or equivalent), and full protective gear.
