  • Explosion Data - Sensitivity to impact: No Tests Run
  • Sensitivity to Static Discharge: No Tests Run
  • Unusual Fire & Explosion Hazards: Improperly Disposed of Stabilant soaked combustible materials might be subject to spontaneous combustion. Heat may build internal pressure in container, leading to rupture of container.
HEALTH EFFECTS DATA
  • As the material is 80% isopropanol it exhibits all of the health hazards of isopropanol but to a lesser degree. The lower concentration of the isopropanol mitigates the defatting and drying effects of the near absolute alcohol's on the skin although there is still a hazard on eye contact. If the container of Stabilant 22A is left uncapped for extended periods at normal room temperatures, the isopropanol will evaporate reducing the hazards somewhat. When applied to contacts the isopropanol will evaporate leaving the nonvolatile portion of the material (Stabilant 22) on the surfaces, and reference should be made to the MSDS for Stabilant 22 as to the potential hazards of that product.
  • LD50 (oral, rat): 5000 mg/kg
  • Skin irritation: The material is a mild irritant and may cause defatting and drying of the skin.
  • Prolonged Skin Exposure: Prolonged and repeated contact may cause dermatitis.
  • First Aid on Skin Exposure: Major spills on clothing require removal of contaminated clothing, then flush area with running water and wash with soap and water. Small area contact, wash with running water, then soap and water. Obtain medical advice.
  • Eye irritation: The vapor is a mild irritant which may cause conjunctivitis and corneal damage. The liquid is a severe eye irritant which may cause permanent eye damage.
  • First Aid on Eye Exposure: Flush eyes with running water for at least 20 minutes holding eyelids open. Obtain medical attention immediately! Treat for isopropanol exposure.
  • Exposure when Inhaled: May cause irritation of the eyes, nose and throat and of the respiratory tract. Overexposure could cause Central Nervous System Depression characterized by headache, dizziness, drowsiness, nausea, vomiting, abdominal pain and incoordination. Severe overexposure could lead to coma and possibly death due to respiratory failure. Remove to fresh air. If not breathing give artificial respiration. Obtain medical 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. DO NOT induce vomiting. If spontaneous vomiting occurs, have victim lean forward with head down to avoid breathing in of vomitus, rinse mouth and administer more water--Transport victim to an emergency facility IMMEDIATELY!
  • Emergency Medical Care: Extreme care must be taken to avoid aspiration of product into lungs, which may result in pulmonary edema.

ECOLOGICAL DATA:
  • Biodegradability: No Tests Run - No Data
  • Fish Toxicity: Harmful to aquatic life at low concentrations. No quantitative data known.
  • Bacterial Inhibition in Influent: No Data
ENGINEERING CONTROLS & SPECIAL PROTECTION INFORMATION

Note: Conditions of use, adequacy of engineering or of other control measures and actual exposure will dictate the need for specific protective devices at the workplace. The recommendations listed in this section indicate the type of equipment which will prevent overexposure to the product.

  • Ventilation: Where the material is being applied by swab or small brush, or from a dropper bottle, it is highly unlikely that sufficient air concentration of the isopropanol could occur under normal ventilation such that a health hazard could be created. Whenever large volumes of the material are being used (>250 mL) or whenever the continually exposed surface area of the material is in excess of 3 Square ft., it is suggested that local exhaust ventilation be provided.
  • Respiratory Protection: Where small amounts are being used with a swab or small brush, or are being dispensed from a dropper bottle, respiratory protection is not needed under normal ventilation conditions. Where large volumes of the material (>250 mL) are being used or where large surface areas are being exposed (e.g. - dipping tanks) the use of a NIOSH/MSHA approved air purifying respirator equipped with organic vapor cartridges be used if exposed to concentrations up to 1000 ppm. Use an air supplied unit if exposed to higher or unknown concentrations. (Such as in bulk handling)
  • Protective Gloves: Rubber, or Neoprene gloves should be worn when the handling of circuit boards or connectors requires constant skin contact with the material.
  • Eye Protection: Goggles or Face shield when there is a potential for eye contact.
  • Footwear: Non slip when handling bulk amounts.
  • Clothing: Rubber or Neoprene protective clothing when handling bulk amounts
  • Other: Not required
  • Bulk Handling: Ground equipment to prevent static discharge accumulation Observe physical safety procedures commensurate with the size of the container involved.
SPECIAL STORAGE PRECAUTIONS
  • Storage Procedures: Store in a cool, dry, well ventilated location away from strong oxidizers.
