Potential Health Effects
Inhalation: Irritant for the upper respiratory system. Pungent taste in
mouth and throat, coughing, labored breathing. Can be a route of absorption by
the body with symptoms like ingestion.
Ingestion: Irritant to the digestive system. Symptoms of sore throat,
abdominal pain, nausea may occur. May cause anemia,gout, headaches, weight loss,
joint pain, and liver or kidney damage.
Skin Contact: Causes irritation to skin. Symptoms include redness,
itching, and pain.
Eye Contact: Causes irritation, redness, and pain.
Chronic Exposure: Prolonged or repeated exposure to this product may
cause symptoms similar to ingestion.
Aggravation of Pre-existing Conditions: Persons with pre-existing skin
disorders, blood disorders or eye problems, or impaired liver, kidney or
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. Water
spray may be used to keep fire exposed containers cool.
Ventilate area of leak or
spill. Wear appropriate personal protective equipment as specified in Section 8.
Spills: Pick up and place in a suitable container for reclamation or disposal,
using a method that does not generate dust.
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 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 half facepiece particulate
respirator (NIOSH type N95 or better filters) may be worn for up to ten times
the exposure limit or the maximum use concentration specified by the appropriate
regulatory agency or respirator supplier, whichever is lowest.. A full-face
piece particulate respirator (NIOSH type N100 filters) may be worn 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.
