**** SECTION 3 - HAZARDS IDENTIFICATION ****
EMERGENCY OVERVIEW
Reacts violently with water. Causes burns.Corrosive.Hygroscopic
(absorbs moisture from the air).
Potential Health Effects
Eye:
Causes severe eye irritation and burns.
Skin:
Causes severe skin irritation and burns.
Ingestion:
Causes gastrointestinal tract burns. May cause central nervous
system effects.
Inhalation:
May cause severe irritation of the respiratory tract with sore
throat, coughing, shortness of breath and delayed lung edema. Causes
chemical burns to the respiratory tract.
Chronic:
No information found.
**** SECTION 4 - FIRST AID MEASURES ****
Eyes:
Immediately flush eyes with plenty of water for at least 15 minutes,
occasionally lifting the upper and lower eyelids. Get medical aid
immediately. Do NOT allow victim to rub eyes or keep eyes closed.
Extensive irrigation with water is required (at least 30 minutes).
Skin:
Get medical aid immediately. Flush skin with plenty of water for at
least 15 minutes while removing contaminated clothing and shoes.
Discard contaminated clothing in a manner which limits further
exposure.
Ingestion:
Never give anything by mouth to an unconscious person. Get medical
aid immediately. Do NOT induce vomiting. If conscious and alert,
rinse mouth and drink 2-4 cupfuls of milk or water.
Inhalation:
Get medical aid immediately. Remove from exposure and move to fresh
air immediately. If not breathing, give artificial respiration. If
breathing is difficult, give oxygen. Do NOT use mouth-to-mouth
resuscitation.
Notes to Physician:
**** SECTION 5 - FIRE FIGHTING MEASURES ****
General Information:
As in any fire, wear a self-contained breathing apparatus in
pressure-demand, MSHA/NIOSH (approved or equivalent), and full
protective gear. During a fire, irritating and highly toxic gases
may be generated by thermal decomposition or combustion. Vapors may
be heavier than air. They can spread along the ground and collect
in low or confined areas. Contact with metals may evolve flammable
hydrogen gas. Containers may explode when heated or if contaminated
with water. Substance will react with water (some violently)
releasing flammable, toxic, or corrosive gases and runoff.
Combustible material; may burn but does not ignite readily.
Extinguishing Media:
Do NOT use straight streams of water. Most foams will react with the
material and release corrosive/toxic gases. Use dry chemical, dry
sand, or carbon dioxide.
**** SECTION 6 - ACCIDENTAL RELEASE MEASURES ****
General Information: Use proper personal protective equipment as indicated
in Section 8.
Spills/Leaks:
Avoid runoff into storm sewers and ditches which lead to waterways.
Clean up spills immediately, observing precautions in the Protective
Equipment section. Sweep up, then place into a suitable container for
disposal. Avoid generating dusty conditions. Remove all sources of
ignition. Provide ventilation. A vapor suppressing foam may be used
to reduce vapors. Stop leak only if you can do so without risk.
**** SECTION 7 - HANDLING and STORAGE ****
Handling:
Use only in a well-ventilated area. Minimize dust generation and
accumulation. Ground and bond containers when transferring material.
Keep container tightly closed. Do not get on skin or in eyes. Do not
ingest or inhale. Discard contaminated shoes.
Storage:
Store in a cool, dry, well-ventilated area away from incompatible
substances. Corrosives area. Keep containers tightly closed.
**** SECTION 8 - EXPOSURE CONTROLS, PERSONAL PROTECTION ****
Engineering Controls:
Use adequate general or local exhaust ventilation to keep airborne
concentrations below the permissible exposure limits.
Exposure Limits
CAS# 10241-05-1:
United States OSHA: 15 mg/m3 TWA (total dust) (listed under
Molybdenum).

Netherlands: (listed as molybdenum): 5 mg/m3 MAC
Russia: (listed as molybdenum): 3 mg/m3 TWA
Russia: (listed as molybdenum): 0.5 mg/m3 STEL
Personal Protective Equipment
Eyes:
Wear appropriate protective eyeglasses or chemical
safety goggles as described by OSHA's eye and face
protection regulations in 29 CFR 1910.133 or European
Standard EN166.
Skin:
Wear appropriate protective gloves to prevent skin
exposure.
Clothing:
Wear appropriate protective clothing to prevent skin
exposure.
Respirators:
Follow the OSHA respirator regulations found in 29
CFR 1910.134 or European Standard EN 149. Use a
NIOSH/MSHA or European Standard EN 149 approved
respirator if exposure limits are exceeded or if
irritation or other symptoms are experienced.
