IV      FIRE AND EXPLOSION HAZARDS DATA



Combustibility: Non-combustible

Extinguishing Media: No fire hazard. Use extinguishing media suitable for type of surrounding fire.



Special Fire-Fighting Procedures: Avoid procedures that may create dust. When fighting a fire that might create dust, wear full

protective equipment, including positive-pressure breathing apparatus.





V       HEALTH HAZARD INFORMATION



Primary Routes of Entry: Inhalation, eyes, skin and ingestion.



Effects of Overexposure:



Inhalation: Breathing dust and fumes can irritate the respiratory tract and cause chest tightness, wheezing and coughing.

Skin Contact: Harmful amounts may be absorbed through the skin. Contact may cause local irritation with reddening and itching.



Eye Contact: May cause moderate to severe eye irritation and possible corneal injury.

Swallowing: May cause abdominal discomfort such as nausea, vomiting or cramps. Also may cause harmless greenish-black

discoloration of the tongue.



Extreme or Repeated Exposure: May result in chronic bronchitis and allegedly causes allergic skin reaction or asthmatic reaction

with possible lung injury in susceptible individuals. When exposure ceases, effects are usually reversible.

EMERGENCY AND FIRST-AID PROCEDURES:



INHALATION: Leave dusty area and get fresh air. Help breathing if necessary.

SKIN: Wash with soap and water. See a physician if irritation occurs.

EYES: Flush with water for 10-20 minutes to make sure no particles remain in the eye. See a physician, preferably an ophthalmolo-

gist, promptly.

INGESTION: Give at least two glasses of water. Induce vomiting if the patient is conscious and call a physician.





VI       REACTIVITY DATA



Stability: Stable. Soluble in hot water and concentrated acids and alkalis. Reacts with chlorine or hydrochloric acid to form vana-

dium oxytrichloride.



Incompatibility (Material to Avoid): Keep Dry. Vanadium pentoxide absorbs moisture from the air.

Conditions to Avoid: None

Hazardous Decomposition Products: None





VII      SPILL OR LEAK PROCEDURES



Steps to Be Taken in Case Material Is Released or Spilled: Material should be swept up or vacuumed, using ventilation to control

the level of airborne dust. Avoid using compressed air or any method that creates airborne dust. If cleanup may create airborne dust,

personnel should wear skin and eye protection as well as respiratory protection.



Waste Disposal Method: Non-recyclable scrap should be disposed in its un-oxidized form in an approved landfill in accordance with

federal, state and local regulations. This material contains vanadium pentoxide , which is included in 40 CFR 302, table 302.4, "List

of Hazardous Substances and Reportable Quantities," with a reportable quantity of 1,000 pounds., and is listed as an acute hazardous

waste (P-120) under 40 CFR 261.33(e). Some states have more restricted listings.





VIII     SPECIAL PROTECTION INFORMATION



Respiratory Protection (Specify Type): For operations such as grinding or polishing, which will produce dusts of metal powder or

oxide above 0.5 mg/m3: NIOSH approved dust-mist-fume respirator

Ventilation: Provide sufficient ventilation to keep exposure to dust below permissible exposure limits.



Protective Gloves: Rubber

Eye Protection: Safety Glasses with side shields. Facilities to flush the eyes with water should be readily available.

Other Protective Clothing or Equipment: Protective gear suitable to prevent contamination.





IX       SPECIAL PRECAUTIONS



Handling and Storage: Material should be kept dry and in closed containers. Personnel should clean up after handling the product

and avoid areas where fume or dust is present.



Labeling: DOT classification: RQ, Hazardous Substance, Solid, n.o.s, ORM-E, NA9188 (Vanadium Pentoxide) IMO Classification:

RQ, Vanadium Pentoxide, 6.1, UN2862, PG II.



TSCA: This material was reported on the initial TSCA inventory.



Carcinogen Listing: National Toxicology Program Annual Report (NTP): Not Listed. International Agency for Research on Cancer

(IARC): Not Listed. OSHA 29 CFR Part 1910, Subpart Z: Not Listed.



Emergency Release Notification: Vanadium pentoxide is listed under SARA III - Section 304 (40 CFR 355) with a threshold

planning quantity (TPQ) of 100/10,000 pounds.

        Some of the chemicals listed herein are research or experimental substances which may be toxic, as defined by various

governmental regulations. In accordance with Environmental Protection Agency regulations and the Toxic Substance Control Act

(TSCA), these materials should only be handled by, or under the direct supervision of, a "technically qualified individual", as defined

in 40 CFR 710.2 (aa).



         The above information is accurate to the best of our knowledge. However, since data, safety standards, and government
