NILE CHEMICALS
CAS No.: 7631-95-0 (Anhydrous); 10102-40-6 (Dihydrate)
Molecular Weight: 241.95
Chemical Formula: Na2MoO4 . 2H2O
Product Codes: 191163
Ingredient CAS No Percent Hazardous --------------------------------------- ------------ ------------ --------- Sodium Molybdate 7631-95-0 99 - 100% Yes
Inhalation:Causes irritation to the respiratory tract. Symptoms may include coughing, shortness of breath. Can be route for absorption of soluble salts of molybdenum.
Ingestion:Moderately toxic because of solubility. Large doses cause severe distress; cramping, vomiting, and hypertension.
Skin Contact:Can be irritating to wet skin causing a rash which is difficult to heal.
Eye Contact:Irritant to soft tissues. Acts as a sensitizer.
Chronic Exposure:No specific information found. Molybdenum is rapidly excreted from the body. Persons exposed for long periods suffer from anemia.
Aggravation of Pre-existing Conditions:Persons with pre-existing skin disorders or eye problems or impaired respiratory function may be more susceptible to the effects of the substance.
Inhalation:Remove to fresh air. If not breathing, give artificial respiration. If breathing is difficult, give oxygen. Get medical attention.
Ingestion:Induce vomiting immediately as directed by medical personnel. Never give anything by mouth to an unconscious person. Get medical attention.
Skin Contact:Immediately flush skin with plenty of water for at least 15 minutes. Remove contaminated clothing and shoes. Get medical attention. Wash clothing before reuse. Thoroughly clean shoes before reuse.
Eye Contact:Immediately flush eyes with plenty of water for at least 15 minutes, lifting lower and upper eyelids occasionally. Get medical attention immediately.
Fire:Not considered to be a fire hazard.
Explosion:Not considered to be an explosion hazard.
Fire Extinguishing Media:Use any means suitable for extinguishing surrounding fire.
Special Information:In the event of a fire, wear full protective clothing and NIOSH-approved self-contained breathing apparatus with full facepiece operated in the pressure demand or other positive pressure mode.
Ventilate area of leak or spill. Wear appropriate personal protective equipment as specified in Section 8
Keep in a tightly closed container. Protect from physical damage. Store in a cool, dry, ventilated area away from sources of heat, moisture and incompatibilities. Containers of this material may be hazardous when empty since they retain product residues (dust, solids); observe all warnings and precautions listed for the product.
Airborne Exposure Limits:-OSHA Permissible Exposure Limit (PEL):5 mg/m3 for soluble molybdenum compounds as Mo
15 mg/m3 total dust, for insoluble molybdenum compounds as Mo -ACGIH Threshold Limit Value (TLV):
Molybdenum, metal and insoluble compounds, inhalable fraction, as Mo: 10 mg/m3
Molybdenum, metal and insoluble compounds, respirable fraction, as Mo: 3 mg/m3
Molybdenum, soluble compounds, respirable fraction, as Mo: 0.5 mg/m3, A3 - Confirmed animal carcinogen with unknown relevance to humans
Ventilation System:A system of local and/or general exhaust is recommended to keep employee exposures below the Airborne Exposure Limits. Local exhaust ventilation is generally preferred because it can control the emissions of the contaminant at its source, preventing dispersion of it into the general work area. Please refer to the ACGIH document, Industrial Ventilation, A Manual of Recommended Practices, most recent edition, for details.
Personal Respirators (NIOSH Approved):If the exposure limit is exceeded and engineering controls are not feasible, a full facepiece particulate respirator (NIOSH type N100 filters) may be worn for up to 50 times the exposure limit or the maximum use concentration specified by the appropriate regulatory agency or respirator supplier, whichever is lowest. If oil particles (e.g. lubricants, cutting fluids. glycerine, etc.) are present, use a NIOSH type R or P filter. For emergencies or instances where the exposure levels are not known, use a full-facepiece positive-pressure, air-supplied respirator. WARNING: Air-purifying respirators do not protect workers in oxygen-deficient atmospheres.
Skin Protection:Wear impervious protective clothing, including boots, gloves, lab coat, apron or coveralls, as appropriate, to prevent skin contact.
Eye Protection:Use chemical safety goggles and/or full face shield where dusting or splashing of solutions is possible. Maintain eye wash fountain and quick-drench facilities in work area.
Appearance:Small white scales or flakes.
Odor:Odorless.
Solubility:84 g/100 g water @ 100C (212F)
Specific Gravity:3.28 @ 18C (64.4F)

Hazardous Decomposition Products:Toxic metal fumes may form when heated to decomposition.
Hazardous Polymerization:Will not occur.
Incompatibilities:Incompatible with alkali metals, most common metals and oxidizing agents. Explodes on contact with molten magnesium. Violent reaction with interhalogens (e.g., bromine pentafluoride; chlorine trifluoride). Incandescent reaction with hot sodium, potassium or lithium.
Conditions to Avoid:Moisture, heat, flames, ignition sources and incompatibles.
