• 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. Vapors form from this product and may travel or be mobilized by air circulation and be ignited by pilot lights, other flames, sparks, heaters, electrical equipment, static discharges or other ignition sources at locations distant from handling point.

As the material is 80% D-Limonene it exhibits all of the health hazards of that material, but to a lesser degree. The lower concentration of the D-Limonene mitigates the defatting and drying effects of D-Limonene on the skin. Although the hazards are moderate, there is still a hazard on eye contact. If the container of Stabilant22L left uncapped for extended periods at normal room temperatures, the D-Limolene evaporates. This reduces the hazards somewhat. When applied to contacts, the D-Limolene 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): 4400 mg/kg
• Skin Irritation: The material is a mild irritant and may cause some 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 an irritant which may cause conjunctivitis and corneal damage. The liquid is an eye irritant which may cause some eye damage.

Note: Conditions of use, adequacy of engineering or of other control measures and actual exposure Mll 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 D-Limolene could occur under normal ventilation such that a health hazard could be created. Whenever large volumes of the material are being used (>500 mL) or whenever the continually exposed surface area of the material is in excess of 3 ft.2 it is suggested that local exhaust ventilation
• 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 (>500 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.
• Observe physical safety procedures commensurate with the size of the container involved.

• Storage Procedures: Store in a cool, dry, well ventilated location away from strong oxidizers.
