Medical Conditions Aggravated byExposure: Pre-existing dust allergies

Emergency and First Aid Procedures:

Inhalation:           Remove victim to fresh air, keep warm and quiet, and give oxygen if breathing is difficult; seek medicalattention

Ingestion:              Give 1-2 glasses of milk or water and induce vomiting, seek medical attention. Never inducevomiting or give anything by mouth to an unconscious person

Skin:      Remove contaminated clothing, brush material off skin, wash affected area with mild soap and water, and seek medical attention if symptoms persist

Eye:        Flush eyes with lukewarm water, lifting upper and lower eyelids for at least 15 minutes and seek medical attention

SECTION VII - PRECAUTIONS FOR SAFE HANDLING AND USE

Steps to be taken in case material is released or spilled:

Wear appropriate respiratoryandprotective equipment specified in section VIII. Isolate spill area, provideventilation and extinguish sources of ignition.  Vacuum up spill using ahigh efficiency particulate absolute (HEPA) air filter and placeina closed container for proper disposal. Takecare not to raisedust.

Waste disposal method:

Disposeof in accordancewith state, local, and federal regulations.

Hazard Label Information:

Store in cool, dry area and in tightly sealed container. Wash thoroughly after handling.

Other:

Store under Argon (Ar) or other inert environment

SECTION VIII - CONTROL MEASURES

ProtectiveEquipmentSummary (Hazard Label Information):

NIOSH approved respirator, impervious gloves, safety glasses, clothes to prevent contact.

Ventilation:

Local Exhaust: To maintain concentration at low exposure levels.Mechanical (General):  Recommended.

Work/Hygienic/Maintenance Practices:

Implement engineering and work practicecontrols to reduce and maintain concentration of exposureat low levels.  Use good housekeeping and sanitation practices.  Do not use tobacco or food in work area. Wash thoroughly before eating or smoking. Do not blow dust off clothing or skin with compressed air.

Please be advised that N/A can either mean Not Applicable or No Data Has Been Established.
