HAZARD IDENTIFICATION
==============================================================================
Route Of Entry Inds - Inhalation: YES Skin: NO Ingestion: YES
Carcinogenicity Inds - NTP: NO IARC: NO OSHA: NO
Health Hazards Acute And Chronic: ACUTE:INHAL OF TUNGSTEN MAY OR MAY NOT CAUSE
TRANSIENT OR PERMANENT LUNG DAMAGE. TUNGSTEN MAY CAUSE SKIN IRRITATION.
HOWEVER, THESE EFFECTS ARE GENERALLY ONLY FOUND WHEN THERE IS CONCURRENT
EXPOSURE TO OTHER DUST(S).
Explanation of Carcinogenicity: NOT RELEVANT.
Signs and Symptoms of Overexposure: SEE HEALTH HAZARDS.
Medical Conditions Aggravated by Overexposure: EXPOSURE TO TUNGSTEN DUST OR
FUME MAY AGGRAVATE CHRONIC RESPIRATORY DISEASE.
==============================================================================
FIRST AID
==============================================================================
EYE:FLUSH W/LARGE AMT OF WATER FOR 15 MINUTES. IF IRRIT OCCURS, SEEK MEDICAL
ATTENTION. SKIN:WASH W/SOAP & WATER. IF IRRITATION OCCURS, SEEK MEDICAL
ATTENTION. INHAL:REMOVE FROM EXPOSURE. IF NECESSARY AID BREATHING AND SEEK
MEDICAL ATTENTIO N. INGEST:SEEK MEDICAL ATTENTION.

FIRE FIGHTING MEASURES
==============================================================================
Flash Point Text: N/A
Auto Ignition Temperature Text:
Lower Limits: N/K Upper Limits: N/K
Extinguishing Media: CLASS D FIRE EXTINGUISHING AGENTS, DRY POWDER.
Fire Fighting Procedures: USE NIOSH/MSHA APPROVED SCBA & FULL PROTECTIVE
EQUIPMENT (FP N).
Unusal Fire/Explosion Hazard: WHEN TUNGSTEN BURNS IN AIR IT FORMS WO*3 WHICH
SUBLIMES ABOVE 750C (TLV 5MG/M3 AS W). UNDER ABNORMAL CNDTNS, TUNGSTEN POWDER
MAY PRESENT A FIRE HAZARD (SUPDAT)
==============================================================================
RELEASE MEASURES
==============================================================================
Spill Release Procedures: AVOID DUST GENERATION. DO NOT CAUSE MATL TO BECOME
AIRBORNE. PROVIDE ADEQ VENT. IF TLV IS EXCEEDED, CLEAN-UP PERSON NEED
NIOSH/MSHA APPRVD DUST RESP. VACUUM (W/APPROP FILTER TO PVNT AIRBORNE DUST LEV
WHICH EXCEED TLV) OR WET CLEAN-UP METH A RE (ING 5)
Neutralizing Agent: NONE SPECIFIED BY MANUFACTURER.
Waste Disposal Methods: DISPOSAL MUST BE I/A/W FEDERAL, STATE & LOCAL
REGULATIONS (FP N).
==============================================================================
HANDLING AND STORAGE
==============================================================================
MAINTAIN GOOD HOUSEKEEPING PROCEDURES TO PVNT DUST ACCUM. WASH EXPOS SKIN @ END
OF WORK SHIFT. DO NOT SHAKE CLTHG, RAGS/OTHER ITEMS TO REMOVE DUST.
==============================================================================
EXPOSURE CONTROLS/PERSONAL PROTECTION
==============================================================================
Respiratory Protection: NIOSH/MSHA APPROVED DUST RESPIRATOR IS REQUIRED IF TLV
IS EXCEEDED.
Ventilation: GENERAL AND LOCAL VENTILATION IS RECOMMENDED.
Protective Gloves: IMPERVIOUS GLOVES (FP N).
Eye Protection: ANSI APPVD SAFETY GLASSES (FP N).
Other Equipment: NONE UNDER NORMAL CONDITIONS.
Work Hygenic Practices: NONE UNDER NORMAL CONDITIONS.
Supplemental Safety & Health: EXPLO HAZ:DEPENDING UPON PARTICLE SIZE,
DISPERSION & EXPOS TO IGNIT SOURCE. THIS IS NOT EXPECTED UNDER NORM CNDTNS.
TUNGSTEN POWDER, PARTICULARLY POWDER <1 MICRON (FSSS) CAN BE IGNITED IN AIR
BY FRICTION DURING BLENDING, MILLING, ETC., IF O VERBLENDED, OVERMILLED, ETC.
FINE POWDERS MAY IGNITE SPONTANIOUSLY IN AIR.
