Section 3 - Hazards Identification
Appearance: white powder.
Warning! Harmful if inhaled. May cause eye and skin irritation with possible burns. May cause
respiratory tract irritation. Hygroscopic (absorbs moisture from the air).
Target Organs: Eyes, skin.
Potential Health Effects
Eye: May result in corneal injury. Contact with eyes may cause severe irritation, and possible eye burns.
Skin: Contact with skin causes irritation and possible burns, especially if the skin is wet or moist.
Ingestion: May cause irritation of the digestive tract.
Inhalation: Harmful if inhaled. May cause irritation of the respiratory tract with burning pain in the
nose and throat, coughing, wheezing, shortness of breath and pulmonary edema.
Chronic: Prolonged or repeated inhalation may cause nosebleeds, nasal congestion, erosion of the
teeth, perforation of the nasal septum, chest pain and bronchitis.
Section 4 - First Aid Measures
Eyes: Immediately flush eyes with plenty of water for at least 15 minutes, occasionally lifting the upper
and lower eyelids. Get medical aid imme diately.
Skin: Get medical aid. Flush skin with plenty of water for at least 15 minutes while removing
contaminated clothing and shoes. Wash clothing before reuse.
Ingestion: Do not induce vomiting. If victim is conscious and alert, give 2-4 cupfuls of milk or water.
Never give anything by mouth to an unconscious person. Get medical aid immediately.
Inhalation: Remove from exposure and move to fresh air immediately. If not breathing, give artificial
respiration. If breathing is difficult, give oxygen. 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. Runoff from fire control or dilution
water may cause pollution.

Section 6 - Accidental Release Measures
General Information: Use proper personal protective equipment as indicated in Section 8.
Spills/Leaks: Vacuum or sweep up material and place into a suitable disposal container. Clean up spills
immediately, observing precautions in the Protective Equipment section. Avoid generating dusty
conditions. Provide ventilation.
Section 7 - Handling and Storage
Handling: Wash thoroughly after handling. Remove contaminated clothing and wash before reuse. Use
with adequate ventilation. Minimize dust generation and accumulation. Do not get in eyes, on skin, or on
clothing. Keep container tightly closed. Avoid ingestion and inhalation.
Storage: Store in a tightly closed container. Store in a cool, dry, well-ventilated area away from
incompatible substances.
Section 8 - Exposure Controls, Personal Protection
Engineering Controls: Good general ventilation should be sufficient to control airborne levels. Facilities
storing or utilizing this material should be equipped with an eyewash facility and a safety shower.
