  • Unusual Fire & Explosion Hazards: Improperly Disposed of Stabilantsoaked combustible materials might be subject to spontaneous combustion.Heat may build internal pressure in container, leading to rupture of container.
    As the material is 80% ethanol it exhibits all of the health hazardsof ethanol but to a lesser degree. The lower concentration of the ethanolmitigates the defatting and drying effects of the near absolute alcohol'son the skin although there is still a hazard on eye contact. If the containerof Stabilant 22E is left uncapped for extended periods at normal room temperatures,the ethanol will evaporate reducing the hazards somewhat. When appliedto contacts the ethanol will evaporate leaving the nonvolatile portionof the material (Stabilant 22) on the surfaces, and reference should bemade to the MSDS for Stabilant 22 as to the potential hazards of that product.
  • LD50 (oral, rat): 7000 mg/kg
  • Skin irritation: The material is a mild irritant and may cause defattingand drying of the skin.
  • Prolonged Skin Exposure: Prolonged and repeated contact may causedermatitis.
  • First Aid on Skin Exposure: Major spills on clothing require removalof contaminated clothing, then flush area with running water and wash withsoap and water. Small area contact, wash with running water, then soapand water. Obtain medical advice.
  • Eye irritation: The vapor is a mild irritant which may cause conjunctivitisand corneal damage. The liquid is a severe eye irritant which may causepermanent eye damage.
  • First Aid on Eye Exposure: Flush eyes with running water for atleast 20 minutes holding eyelids open. Obtain medicalattention immediately! Treat for ethanol exposure.
  • Exposure when Inhaled: May cause irritation of the eyes, nose andthroat and of the respiratory tract. Overexposure could cause Central NervousSystem Depression characterized by headache, dizziness, drowsiness, nausea,vomiting, abdominal pain and incoordination. Severe overexposure couldlead to coma and possibly death due to respiratory failure. Remove to freshair. If not breathing give artificial respiration. Obtainmedical attention immediately.
  • First Aid oral ingestion: If victim is alert and not convulsing,rinse out mouth and give 1/2 to 1 glass of water to dilute material. DONOT induce vomiting. If spontaneous vomiting occurs, have victimlean forward with head down to avoid breathing in of vomitus, rinse mouthand administer more water--Transport victim toan emergency facility IMMEDIATELY!

  • Hazardous Polymerization or Reactivity: Avoid oxidizing materials.Can react violently with potassium oxides and potassium. Can ignite incontact with platinum black catalyst.
  • Biodegradability: No Tests Run - No Data
  • Fish Toxicity: Harmful to aquatic life at low concentrations. Noquantitative data known.
  • Bacterial Inhibition in Influent: No Data
    Note: Conditions of use, adequacy of engineering or of othercontrol measures and actual exposure will dictate the need for specificprotective devices at the workplace. The recommendations listed in thissection indicate the type of equipment which will prevent overexposureto the product.
  • Ventilation: Where the material is being applied by swab or smallbrush, or from a dropper bottle, it is highly unlikely that sufficientair concentration of the ethanol could occur under normal ventilation suchthat a health hazard could be created. Whenever large volumes of the materialare being used (>250 mL) or whenever the continually exposed surface areaof the material is in excess of 3 ft.2 it is suggested that local exhaustventilation be provided.
  • Respiratory Protection: Where small amounts are being used witha swab or small brush, or are being dispensed from a dropper bottle, respiratoryprotection is not needed under normal ventilation conditions.--Where largevolumes of the material (>250 mL) are being used or where large surfaceareas are being exposed (e.g. - dipping tanks) the use of a NIOSH/MSHAapproved air purifying respirator equipped with organic vapor cartridgesbe used if exposed to concentrations up to 1000 ppm. Use an air suppliedunit if exposed to higher or unknown concentrations. (Such as in bulk handling)
  • Protective Gloves: Rubber, or Neoprene gloves should be worn whenthe handling of circuit boards or connectors requires constant skin contactwith the material.
  • Eye Protection: Goggles or Face shield when there is a potentialfor eye contact.
  • Footwear: Non slip when handling bulk amounts.
  • Clothing: Rubber or Neoprene protective clothing when handling bulkamounts
  • Other: Not required
  • Bulk Handling: Ground equipment to prevent static discharge accumulationObserve physical safety procedures commensurate with the size of the containerinvolved.
  • Storage Procedures: Store in a cool, dry, well ventilated locationaway from strong oxidizers.
