• Percent: 100% 

Eye Contact: Any material that contacts the eye should be washed out immediately with water. If easy to do, remove contact lenses. Get medical attention if irritation develops or persists. 

Skin Contact: Wash off with soap and water. Get medical attention if irritation develops or persists. 

Inhalation: Move to fresh air. Treat symptomatically. Get medical attention if symptoms persist. 

Ingestion: Seek medical advice. If ingestion of a large amount does occur, call a poison control center immediately. 

Notes To Physician: Treat symptomatically 

Flammable Properties: This product is not flammable. 

Extinguishing Media:

• Suitable Extinguishing Media: Use extinguishing measures that are appropriate to local circumstances and the surrounding environment. 

• Unsuitable Extinguishing Media: None known. 

Protection of Firefighters:

• Protective Equipment and Precautions For Firefighters: Firefighters should wear full protective gear. Wear full protective clothing, including helmet, self-contained positive pressure or pressure demand breathing apparatus, protective clothing and face mask. 

• Special Protective Equipment For Firefighters: As in any fire, wear self-contained breathing apparatus pressure-demand, MSHA/NIOSH (approved or equivalent) and full protective gear. 

Personal Precautions: Keep unnecessary personnel away. Ventilate the area. Wear appropriate protective equipment and clothing during clean-up. 

Environmental Precautions: Prevent further leakage or spillage if safe to do so. 

Methods For Containment: If sweeping of a contaminated area is necessary use a dust suppressant agent which does not react with the product. Prevent entry into waterways, sewer, basements or confined areas. 

Methods For Cleaning Up: Avoid dust formation. 

• Small Spills: Sweep up or vacuum up spillage and collect in suitable container for disposal. 

• Large Spills: Collect dust or particulates using a vacuum cleaner with a HEPA filter. Reduce airborne dust and prevent scattering by moistening with water. 

*Never return spills in original containers for re-use. Clean contaminated surface thoroughly. Clean up in accordance with all applicable regulations. 

Handling: Avoid contact with eyes, skin, and clothing. Wash hands thoroughly after handling. See Section 8 of the MSDS for Personal Protective Equipment. 

Storage: Keep containers tightly closed. 

Exposure Guidelines: No exposure standards allocated. 

Engineering Controls: Good general ventilation (typically 10 air changes per hour) should be used. Ventilation rates should be matched to conditions. If applicable, use process enclosures, local exhaust ventilation, or other engineering controls to maintain airborne levels below recommended exposure limits. If exposure limits have not been established, maintain airborne levels to an acceptable level. 

Personal Protective Equipment: 

• Eye/Face Protection: Use tight fitting goggles if dust is generated. 

• Skin Protection: Wear appropriate clothing to prevent repeated or prolonged skin contact. 

• Respiratory Protection: Wear respirator if there is dust formation. 

General Hygiene Considerations: Provide eyewash station and safety shower. Always observe good personal hygiene measures, such as washing after handling the material and before eating, drinking, and/or smoking. Routinely wash work clothing and protective equipment to remove contaminants.
