Section 3 - HAZARDS IDENTIFICATION
EMERGENCY OVERVIEW 
Irritating to eyes, respiratory system and skin.Hygroscopic (absorbs moisture from the air). 
Potential Health Effects 
Eye: 
Causes severe eye irritation and possible burns. 
Skin: 
Causes skin irritation. Not expected to cause an allergic skin reaction. 
Ingestion: 
May be harmful if swallowed. 
Inhalation: 
Dust is irritating to the respiratory tract. 
Chronic: 
Chronic exposure may cause effects similar to those of acute exposure. 
Section 4 - FIRST AID MEASURES
Eyes: In case of contact, immediately flush eyes with plenty of water for at least 15 minutes. Get medical aid immediately. 
Skin: 
In case of contact, flush skin with plenty of water. Remove contaminated clothing a
nd shoes. Get medical aid if irritation develops and 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: 
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. During a fire, irritating and highly toxic gases may be generated by thermal decomposition or combustion. This material in sufficient quantity and reduced particle size is capable of creating a dust explosion. Contact with metals may evolve flammable hydrogen gas. 
Extinguishing Media: 
Use water spray, dry chemical, or carbon dioxide. 
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. 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. Keep container tightly closed. Avoid breathing dust. Do not get in eyes. Avoid contact with skin and clothing. 
Storage: 
Store in a cool, dry, well-ventilated area away from incompatible substances.
