EMERG ENCY AND FIRST AID PROCEDURES :

INHALATION: If irritation of the nose and throat occurs from exposure to dusts, move away from exposure and into fresh air. If

irritation persists, seek medical attention. If victim is not breathing or if breathing difficulties develop artificial respiration or oxygen

should be adm inistered by qualified personnel. Seek m edical attention.

INGESTION: If victim is conscious and alert, give 2 to 3 cups of milk or water to drink. Seek medical attention.

SKIN: No first aid is normally required but if irritation or redness develop from exposure to dusts, remove contaminated clothing and

flush the affected area(s) with large quantities of clean water. If the effects persist, seek medical attention.

EYE: For contact with dusts, flush the affected eye(s) with clean water. If irritation or redness develop, seek medical attention.

VI REACTIVITY DATA

Stability: Stable

Conditions to Avoid: None

Incompatibility (Material to Avoid): Avoid contact with strong oxidizing agents.

Hazardous Decomposition Products: CO, CO2 evolved when exposed to O2 at temperatures above 500 oC.

Hazardous Polymerization: Will not occur.

VII SPILL OR LEAK PROC EDURES

Steps to be Taken in Case Material is Released or Spilled: Turn off ignition sources. Remove by mechanical means and place

material in metal container temporarily for later disposal. Clean-up procedure should insure minimizing dust; vacuum dust instead of

sweep, for example.

Waste Disposal Method: In accordance w ith Local, State and Federal Waste Disposal Regulations.

VIII SPECIAL PROTECTION INFORMATION

Respiratory Protection (Specify Type): Wear NIOSH approved respirator for nuisance dust when crushing or machining.

Ventilation: Use local exhaust to maintain concentrations at or below PEL, TLV. General exhaust is recommended.

Protective Gloves: Not normally required. If dusts are expected to be generated, the use of protective gloves is advised to prevent

skin contact and possible irritation.

Eye Protection: Safety glasses

IX SPECIAL PRECAUTIONS

Work Practices: Implement engineering and work practice controls to reduce and maintain concentration of exposure. 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. Maintain eyewash capable of sustained flushing, safety drench shower and

facilities for washing.
