  Potential Health Effects
  ----------------------------------
  Inhalation: May cause
  irritation to the respiratory tract. Symptoms may include coughing and
  shortness of breath.
  Ingestion: Large oral doses may
  cause irritation to the gastrointestinal tract.
  Skin Contact: May cause
  irritation with redness and pain.
  Eye Contact: May cause
  irritation, redness and pain.
  Chronic Exposure: No
  information found.
  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. Get medical attention.
  Skin Contact: Immediately flush
  skin with plenty of water for at least 15 minutes. Remove contaminated
  clothing and shoes. Wash clothing before reuse. Thoroughly clean shoes before
  reuse. Get medical attention if irritation develops.
  Eye Contact: Immediately flush
  eyes with plenty of water for at least 15 minutes, lifting upper and lower
  eyelids occasionally. Get medical attention if irritation persists.
  
  5. Fire Fighting
  Measures
  
  
  Fire: As with most organic
  solids, fire is possible at elevated temperatures or by contact with an
  ignition source.
  Explosion: Fine dust dispersed
  in air in sufficient concentrations, and in the presence of an ignition source
  is a potential dust explosion hazard.
  Fire Extinguishing Media: Water
  spray, dry chemical, alcohol foam, or carbon dioxide.
  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.
  
  6. Accidental
  Release Measures
  
  
  Ventilate area of leak or spill. Wear appropriate personal protective
  equipment as specified in Section 8. Spills: Sweep up and containerize for
  reclamation or disposal. Vacuuming or wet sweeping may be used to avoid dust
  dispersal.
  
  
  
  7. Handling and
  Storage
  
  
  Keep in a tightly closed container, stored in a cool, dry, ventilated area.
  Protect against physical damage. 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: Wear
  protective gloves and clean body-covering clothing.
  Eye Protection: Use chemical
  safety goggles. Maintain eye wash fountain and quick-drench facilities in work
  area.
