Section 3 - HAZARDS IDENTIFICATION
EMERGENCY OVERVIEW
Hygroscopic (absorbs moisture from the air).
Potential Health Effects
Eye:
Dust may cause mechanical irritation.
Skin:
Low hazard for usual industrial handling.
Ingestion:
No hazard expected in normal industrial use.
Inhalation:
May cause respiratory tract irritation.
Chronic:
Chronic inhalation of dust may lead to silicosis. Chronic inhalation can cause pneumoconiosis.

Chronic:
Chronic inhalation of dust may lead to silicosis. Chronic inhalation can cause pneumoconiosis.
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. If irritation develops, 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. Wash clothing before reuse.
Ingestion:
If swallowed, do not induce vomiting unless directed to do so by medical personnel. Never give anything by mouth to an unconscious person. Get medical aid.
Inhalation:
If inhaled, remove to fresh air. If not breathing, give artificial respiration. If breathing is difficult, give oxygen. Get medical aid.
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. Substance is noncombustible.
Extinguishing Media:
Use extinguishing media most appropriate for the surrounding fire.

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. Material is a regenerative adsorbent capable of taking up and holding about 4X its weight of water. If spilled, it will adsorb water vapor from the air and any moisture from surroundings.
