May be harmful if absorbed through skin. May cause skin irritation.

Potential Health Effects
Eye:Causes eye burns.
Skin: May be harmful if absorbed through skin. Causes skin irritation.
Ingestion: May be harmful if swallowed.
Inhalation: Toxic if inhaled. Causes respiratory tract irritation.
Chronic: No information found.

Section 4 - First Aid Measures 
Eyes:In case of eye contact,Flush eyes with water as a precaution.
Skin: In case of skin contact,Wash off with soap and plenty of water.
Ingestion: If swallowed,Never give anything by mouth to an unconscious person. Rinse mouth with water.
Inhalation: If breathed in, move person into fresh air. If not breathing, give artificial respiration.
Notes to Physician: Treat symptomatically and supportively.

Section 5 - Fire Fighting Measures 
General Information: 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.
Extinguishing media: Use agent most appropriate to extinguish fire. In case of fire use Use water spray, alcohol-resistant foam, dry chemical or carbon dioxide. Wear self contained breathing apparatus for fire fighting if necessary.

Section 6 - Accidental Release Measures 
Personal precautions, protective equipment and emergency procedures: Avoid dust formation. Avoid breathing vapors, mist or gas.
Environmental precautions: Do not let product enter drains.
Methods and materials for containment and cleaning up: Sweep up and shovel. Keep in suitable, closed containers for disposal.
Reference to other sections: For disposal see section 13

Section 7 - Handling and Storage 
Precautions for safe handling: Provide appropriate exhaust ventilation at places where dust is formed.Normal measures for preventive fire protection.
Store in cool place. Keep container tightly closed in a dry and well-ventilated place. Containers which are  opened must be carefully resealed and kept upright to prevent leakage.
Store under inert gas. Moisture sensitive.

Section 8 - Exposure Controls, Personal Protection 
Engineering Controls: Use adequate ventilation to keep airborne concentrations low.

Personal Protective Equipment
Eyes: Tightly fitting safety goggles.  Faceshield (8-inch minimum). Use equipment for eye protection tested and approved under appropriate government standards such as NIOSH (US) or EN 166(EU).
Skin: Handle with gloves. Gloves must be inspected prior to use. Use proper glove removal technique (without touching glove's outer surface) to avoid skin contact with this product. Dispose of contaminated gloves after use in accordance with applicable laws and good laboratory practices. Wash and dry hands.
The selected protective gloves have to satisfy the specifications of EU Directive 89/686/EEC and the standard EN 374 derived from it.
Clothing: Wear appropriate protective clothing to minimize contact with skin.
Respirators: Where risk assessment shows air-purifying respirators are appropriate use a full-face respirator with multi-purpose combination (US) or type ABEK (EN 14387) respirator cartridges as a backup to engineering controls. If the respirator is the sole means of protection, use a full-face supplied air
respirator. Use respirators and components tested and approved under appropriate government standards such as NIOSH (US) or CEN (EU).
