Section 3 - Hazards Identification

EMERGENCY OVERVIEW
Appearance: bright yellow crystals.
Danger! Strong oxidizer in aqueous solution.
Solution may ignite combustible materials. May cause severe eye and
skin irritation with possible burns. May cause severe respiratory and
digestive tract irritation with possible burns. Corrosive to metal.
Refrigerate upon arrival below 4癈/39癋.
Target Organs: Eyes, skin, mucous membranes.
Potential Health Effects
Eye:
Exposure to particulates or solution may cause conjunctivitis,
ulceration, and corneal abnormalities.
Skin:
Contact with skin causes irritation and possible burns, especially
if the skin is wet or moist. May be harmful if absorbed through the
skin.
Ingestion:
May cause severe gastrointestinal tract irritation with nausea,
vomiting and possible burns.
Inhalation:
May cause burns to the respiratory tract. May be harmful if inhaled.
Chronic:
Aerosols of water-soluble molybdenum compounds can affect the
respiratory tract if inhaled. Animal data from chronic inhalation
studies have shown inflammatory changes in the lungs of rats, with
cellular aggregates resembling nodules, which are consistent with
some of the earlier clinical reports of lung problems among exposed
workers. Data from a NTP study indicate that molybdenum trioxide, a
soluble compound, is a likely animal carcinogen.
|
Section 4 - First Aid Measures
|
Eyes:
In case of contact, immediately flush eyes with plenty of water for a
t least 15 minutes. Get medical aid immediately.
Skin:
In case of contact, immediately flush skin with plenty of water for
at least 15 minutes while removing contaminated clothing and shoes.
Get medical aid immediately. Wash clothing before reuse.
Ingestion:
If swallowed, do NOT induce vomiting. Get medical aid immediately.
If victim is fully conscious, give a cupful of water. Never give
anything by mouth to an unconscious person.
Inhalation:
If inhaled, remove to fresh air. If not breathing, give artificial
respiration. If breathing is difficult, give oxygen. Get medical aid.
Notes to Physician:
Treat symptomatically and supportively.
|
Section 5 - Fire Fighting Measures
|
General Information:

Section 6 - Accidental Release Measures
|
General Information: Use proper personal protective equipment as indicated
in Section 8.
Spills/Leaks:
Vacuum or sweep up material and place into a suitable disposal
container. Avoid generating dusty conditions. Provide ventilation.
Keep combustibles (wood, paper, oil, etc.,) away from spilled
material. Do not use metal tools.
|
Section 7 - Handling and Storage
|
Handling:
Wash thoroughly after handling. Wash hands before eating. Remove
contaminated clothing and wash before reuse. Minimize dust generation
and accumulation. Do not get in eyes, on skin, or on clothing. Do not
ingest or inhale. Keep from contact with clothing and other
combustible materials. Discard contaminated shoes. Use only with
adequate ventilation. Do not use with metal spatula or other metal
items.
Storage:
Store in a cool, dry place. Do not store in metal containers. Keep
containers tightly closed. Refrigerate upon arrival below 4癈/39癋.
|
Section 8 - Exposure Controls, Personal Protection
|
Engineering Controls:
Facilities storing or utilizing this material should be equipped
