Potential Health Effects
----------------------------------
Limited health information was found in the published literature to perform a complete hazard evaluation for
this substance. Special precautions must be used in handling and storage. Protective equipment should be
chosen using professional judgment.
Inhalation: No specific information found. Probably irritating to respiratory tract.
Ingestion: Effects not determined. Probably irritating to the gastro-intestinal tract.
Skin Contact: No specific information found. Probably irritating to moist skin.
Eye Contact: No specific information found. Probably irritating to eye tissues.
Chronic Exposure: Not determined.
Aggravation of Pre-existing Conditions: No information found.
4. First Aid Measures
Inhalation: Remove to fresh air. Get medical attention for any breathing difficulty.
Ingestion: Induce vomiting immediately as directed by medical personnel. Never give anything by mouth to an
unconscious person.
Skin Contact: Remove any contaminated clothing. Wash skin with soap or mild detergent and water for at least
15 minutes. Get medical attention if irritation develops or persists.
Eye Contact: Wash eyes with plenty of water for at least 15 minutes. Call a physician.
5. Fire Fighting Measures
Fire: Not considered a fire hazard.
Explosion: Not considered an explosion hazard.
Fire Extinguishing Media: Water spray, dry chemical, alcohol foam, or carbon dioxide.
6. Accidental Release Measures
Wear appropriate personal protective equipment as specified in Section 8. Spills: Use absorbent material and
containerize for reclamation or disposal.
7. Handling and Storage
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.
8. Exposure Controls/Personal Protection
Airborne Exposure Limits: None established.
Ventilation System: A system of local and/or general exhaust is recommended to keep employee exposures as
low as possible. 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): For conditions of use where exposure to dust or mist is apparent
and engineering controls are not feasible, a particulate respirator (NIOSH type N95 or better filters) may be
worn. 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-face positive-pressure, air-
supplied respirator. WARNING: Air-purifying respirators do not protect workers in oxygen-deficient
atmospheres.
Skin Protection: Gloves and lab coat.
Eye Protection: Use chemical safety goggles. Maintain eye wash fountain and quick-drench facilities in work
area.
