SECTION 4. FIRST AID MEASURES

Inhalation: Immediately call a poison center or doctor. Effects of exposure (inhalation) to substance may be delayed.
Move victim to fresh air. Give artificial respiration if victim is not breathing. Administer oxygen if breathing is
difficult. Keep victim warm and quiet. Treat symptomatically and supportively. Ensure that medical
personnel are aware of the material(s) involved and take precautions to protect themselves.
Skin contact: For severe burns, immediate medical attention is required. Immediately call a poison center or doctor.
Remove and wash contaminated clothing before re-use. In case of contact with substance, immediately
flush skin with running water for at least 20 minutes. Treat symptomatically and supportively. Ensure that
medical personnel are aware of the material(s) involved and take precautions to protect themselves.
Eye contact: IMMEDIATELY flush eyes with running water for at least 15 minutes, keeping eyelids open. Eye contact
with vapors or substance may cause severe injury, burns, or death. Call emergency medical service. Move
victim to fresh air. Check for and remove any contact lenses. Keep victim warm and quiet. Treat
symptomatically and supportively. Effects of exposure to substance may be delayed. Ensure that medical
personnel are aware of the material(s) involved and take precautions to protect themselves.
Ingestion: Do not induce vomiting with out medical advice. Call a physician or Poison Control Center immediately. Do
not use mouth-to-mouth method if victim ingested the substance; give artificial respiration with the aid of a
pocket mask equipped with a one-way valve or other proper respiratory medical device. Loosen tight
clothing such as a collar, tie, belt or waistband. If a person vomits place them in the recovery position so
that vomit will not reenter the mouth and throat. Rinse mouth. Keep victim warm and quiet. Treat
symptomatically and supportively. Ensure that medical personnel are aware of the material(s) involved and
take precautions to protect themselves.
Symptoms/effects:
Acute: Pain. Redness.
Delayed: No data available
Immediate medical attention: WARNING: It might be hazardous to the person providing aid to give mouth-to-mouth respiration, because
the inhaled material is corrosive. For severe burns, immediate medical attention is required. If breathing
has stopped, perform artificial respiration. Use first aid treatment according to the nature of the injury.
Ensure that medical personnel are aware of the material(s) involved and take precautions to protect
themselves.


SECTION 5. FIREFIGHTING MEASURES

Suitable extinguishing media: Use water. Carbon Dioxide (CO2 ) provide limited control Consult with local fire authorities before
attempting large scale fire fighting operations.
Unsuitable extinguishing media: Do NOT use dry chemicals or foams.
Specific hazards arising from the chemical
Hazardous combustion products: These products include: Phosphates Metallic oxides
Other specific hazards: Closed containers may explode from heat of a fire.
Special precautions for fire-fighters:
Use water spray or fog; do not use straight streams. Dike fire-control water for later disposal; do not scatter the material. These substances will
accelerate burning when involved in a fire. May ignite combustibles (wood, paper, oil, clothing, etc.). Runoff to sewer may create fire or explosion hazard.
Containers may explode when heated. Move containers from fire area if you can do it without risk.
Special protective equipment for fire-fighters:
Wear positive pressure self-contained breathing apparatus (SCBA). Structural fire fighters' protective clothing provides limited protection in fire situations
ONLY; it may not be effective in spill situations. Wear chemical protective clothing which is specifically recommended by the manufacturer. It may
provide little or no thermal protection.


SECTION 6. ACCIDENTAL RELEASE MEASURES

Personal precautions: Avoid contact with skin, eyes, and clothing. Keep people away from and upwind of spill/leak. Use sparkproof
tools and explosion-proof equipment. Remove all sources of ignition. Do not touch damaged
containers or spilled material unless wearing appropriate protective clothing (Section 8). Warn
unnecessary personnel to move away. Stop leak if you can do it without risk. Ensure adequate ventilation.
Isolate the hazard area and deny entry to unnecessary and unprotected personnel.
Personal protective equipment: Wear eye protection (splash goggles) and face protection (full length face shield). Lab coat. Dust
respirator. Be sure to use a MSHA/NIOSH approved respirator or equivalent. Wear protective gloves
(nitrile).
Emergency procedures: Prevent dust cloud. ELIMINATE all ignition sources (no smoking, flares, sparks or flames in the immediate
area). Do not touch damaged containers or spilled material unless wearing appropriate protective clothing.
Warn personnel to move away. Prevent entry into sewers, basements or confined areas; dike if needed.
Methods and materials for containment and cleaning up:
ELIMINATE all ignition sources (no smoking, flares, sparks, or flames in immediate area). Stop leak if without risk. Keep away from combustible
materials, reducing agents, acids, metal powders, light, heat, and sources of ignition. Do not get water inside container Absorb with an inert material and
put the spilled material in an appropriate waste disposal container. Ventilate the area. Use clean non-sparking tools to collect absorbed material.
Environmental precautions:
Prevent further leakage or spillage if safe to do so. Water runoff can cause environmental damage. Prevent entry into sewers, basements or confined
areas; dike if needed.


SECTION 7. HANDLING AND STORAGE

Precautions for safe handling: Avoid inhalation of vapor or mist. Manipulate under an adequate fume hood. Avoid contact with skin and
eyes. Avoid contact with combustible material (wood, paper, oil, clothing…). Keep away from heat and
sources of ignition. Use process enclosures, local exhaust ventilation, or other engineering controls to
keep airborne levels below recommended exposure limits. Keep container dry. Handle and open container
with care. Wear suitable protective clothing, gloves and eye/face protection. When using do not eat, drink,
or smoke. Keep away from sources of ignition.
Conditions for safe storage: Keep containers tightly closed in a cool, well-ventilated place. Keep away from combustible materials.
Keep away from sources of ignition. Store and use away from heat, sparks, open flame, or any other
ignition source. Store locked up. Keep away from incompatibles. Containers which are opened must be
carefully resealed and kept upright to prevent leakage. Avoid prolonged storage periods.
Storage incompatibilities: Combustible substances, Reducing Agents


SECTION 8. EXPOSURE CONTROLS/PERSONAL PROTECTION

Exposure limits:
ACGIH TLV (TWA): 0.5 mg (Mo)/m3 (R)

See more Molybdenum products. Molybdenum (atomic symbol: Mo, atomic number: 42) is a Block D, Group 6, Period 5 element with an atomic weight of 95.96. Molybdenum Bohr ModelThe number of electrons in each of molybdenum's shells is [2, 8, 18, 13, 1] and its electron configuration is [Kr] 4d5 5s1. The molybdenum atom has a radius of 139 pm and a Van der Waals radius of 209 pm. In its elemental form, molybdenum has a gray metallic appearance. Molybdenum was discovered by Carl Wilhelm in 1778 and first isolated by Peter Jacob Hjelm in 1781. Molybdenum is the 54th most abundant element in the earth's crust. Elemental MolybdenumIt has the third highest melting point of any element, exceeded only by tungsten and tantalum. Molybdenum does not occur naturally as a free metal, it is found in various oxidation states in minerals. The primary commercial source of molybdenum is molybdenite, although it is also recovered as a byproduct of copper and tungsten mining. The origin of the name Molybdenum comes from the Greek word molubdos meaning lead.

Phosphorus Bohr ModelSee more Phosphorus products. Phosphorus (atomic symbol: P, atomic number: 15) is a Block P, Group 15, Period 3 element. The number of electrons in each of Phosphorus's shells is 2, 8, 5 and its electronic configuration is [Ne] 3s2 3p3. The phosphorus atom has a radius of 110.5.pm and its Van der Waals radius is 180.pm. Phosphorus is a highly-reactive non-metallic element (sometimes considered a metalloid) with two primary allotropes, white phosphorus and red phosphorus its black flaky appearance is similar to graphitic carbon. Compound forms of phosphorus include phosphates and phosphides. Phosphorous was first recognized as an element by Hennig Brand in 1669 its name (phosphorus mirabilis, or "bearer of light") was inspired from the brilliant glow emitted by its distillation.
