3.1 EMERGENCY OVERVIEW

Appearance: Transparent colorless

Physical State: Liquid

Odor: Slight ethanol/acetone-like

Hazards of product: WARNING! FLAMMABLE. CAUSES EYE IRRITATION. MAY CAUSE DIZZINESS AND DROWSINESS.

3.2 POTENTIAL HEALTH EFFECTS

Effects of Single Acute Overexposure

Inhalation: High concentrations of vapor may cause central nervous system depression, with weakness, drowsiness, and loss of consciousness. Vapor causes irritation of the respiratory tract, with coughing and chest discomfort.

Eye Contact: Causes irritation, experienced as stinging and discomfort or pain. Corneal injury may occur.

Skin Contact: May cause minor irritation with itching and possible slight local redness. Prolonged or repeated contact may cause defatting and drying of the skin.

Skin Absorption: Exposure to small quantities is not expected to cause adverse health effects. Widespread or prolonged exposure may result in the absorption of harmful amounts of material, particularly in infants, leading to signs and symptoms as described for swallowing.

Swallowing: Slightly toxic. May cause dizziness, faintness, drowsiness, decreased awareness and responsiveness, lack of coordination, abdominal discomfort, nausea, vomiting and diarrhea.

Chronic, Prolonged or Repeated Overexposure

Effects of Repeated Overexposure: Prolonged or repeated skin exposure may cause defatting of the skin.

Other Effects of Overexposure: None currently known.

Medical Conditions Aggravated by Exposure: Skin contact may aggravate an existing dermatitis.

IV. FIRST AID PROCEDURES

4.1 INHALATION: Remove to fresh air. Give artificial respiration if not breathing. If breathing is difficult, oxygen may be given by qualified personnel. Obtain medical attention.

4.2 EYE CONTACT: Immediately flush eyes with water and continue washing for several minutes. Remove contact lenses, if worn. Obtain medical attention

4.3 SKIN CONTACT: Remove contaminated clothing. Wash skin with soap and water. If irritation persists or if contact has been prolonged, obtain medical attention.

4.4 SWALLOWING: If patient is fully conscious, give two glasses of water. Induce vomiting. This should be done only by medical or experienced first-aid personnel. Obtain medical attention.

4.5 NOTES TO PHYSICIAN: There is no specific antidote. Treatment of overexposure should be directed at the control of symptoms and the clinical condition of the patient.

5.2 EXTINGUISHING MEDIA: Extinguish fires with water spray or apply alcohol-type or all-purpose-type foam by manufacturers recommended techniques for large fires. Use carbon dioxide or dry chemical media for small fires.

5.3 EXTINGUISHING MEDIA TO AVOID: No information currently available.

5.4 SPECIAL FIRE FIGHTING PROCEDURES: Use water spray to cool fire-exposed containers and structures. Use water spray to disperse vapors; reignition is possible.

5.5 SPECIAL PROTECTIVE EQUIPMENT FOR FIREFIGHTERS: Use self- contained breathing apparatus and protective clothing.

5.6 UNUSUAL FIRE AND EXPLOSION HAZARDS: Vapors form from this product and may travel or be moved by air currents and ignited by pilot lights, other flames, smoking, sparks, heaters, electrical equipment, static discharges or other ignition sources at locations distant from product handling point. Vapors from this material may settle in low or confined areas or travel a long distance to an ignition source and flash back explosively. Static ignition hazard can result from handling and use. Electrically bond and ground all containers, personnel and equipment before transfer or use of material. Use proper bonding and grounding during product transfer as described in National Fire Protection Association Document NFPA 77.

This material may produce a floating fire hazard.

Flame may be invisible. Approach fire with caution.

5.7 HAZARDOUS COMBUSTION PRODUCTS: Burning can produce the following products: Carbon monoxide and/or carbon dioxide. Carbon monoxide is highly toxic if inhaled; carbon dioxide in sufficient concentrations can act as an asphyxiant

VI. ACCIDENTAL RELEASE MEASURES

Steps to be taken if Material is Released or Spilled: Extinguish and do not turn on any ignition source until the area is determined to be free from fire or explosion hazard. Small spills can be flushed with large amounts of water-~ larger spills should be collected for disposal.

Personal Precautions: Avoid contact with eyes. Wear suitable protective equipment.

VII. HANDLING AND STORAGE

General Handling: Keep away from heat, sparks and flame. Avoid contact with eyes. Keep container closed. Use with adequate ventilation. Vapor forms from this product and may travel or be moved by air currents and ignited by pilot lights, other flames, smoking, sparks, heaters, electrical equipment, static discharges or other ignition sources at locations distant from product handling point and may flash back explosively.

Wash thoroughly after handling. FOR INDUSTRY USE ONLY.

Ventilation: General (mechanical) room ventilation is expected to be satisfactory where this product is stored and handled in closed equipment. Special, local ventilation is needed at points where vapors can be expected to escape to the workplace air.

Other Precautions: Vapor may settle in low or confined areas, or travel a long distance to an ignition source and flash back explosively.

STORAGE: Store in grounded fireproof cabinets.

VIII. EXPOSURE CONTROLS AND PERSONAL PROTECTION

8.1 EXPOSURE LIMITS

Component Exposure Limits Skin Form

In the Exposure Limits Chart above, if there is no specific qualifier (L e., Aerosol) listed in the Form Column for a particular limit~, the listed limit includes all airborne forms of the substance that can be inhaled.

A “Yes” in the Skin Column indicates a potential significant contribution to overall exposure by the skin route, including mucous membranes and the eyes, either by contact with vapors or by direct skin contact with the substance. A “Blank” in the Skin Column indicates that exposure by the skin route is not a potential significant contributor to overall exposure.

8.2 PERSONAL PROTECTION

Respiratory Protection: Use self-contained breathing apparatus in high vapor concentrations.

Eye Protection: Monogoggles.

Protective Gloves: Plastic, Rubber

Other Protective Equipment: Eye Bath, Safety Shower

8.3 ENGINEERING CONTROLS

PROCESS HAZARD: Sudden release of hot organic chemical vapors or mists from process equipment operating at elevated temperature and pressure, or sudden ingress of air into hot equipment under a vacuum, may result in ignitions without the presence of obvious ignition sources. Published “autoignition” or “ignition” temperature values cannot be treated as safe operating temperatures in chemical processes without analysis of the actual process conditions. Any use of this product in elevated-temperature processes should be thoroughly evaluated to establish and maintain safe operating conditions.

SIGNIFICANT DATA WITH POSSIBLE RELEVANCE TO HUMANS

The following is a summary of TSCA Section 4 Test Rule results: Large doses (>800 mg/kg/day) of lsopropanol given orally to pregnant rats during the critical period of gestation produced slight decreases in fetal weight. These doses also caused evidence of toxicity in the mothers. Oral doses as high as 480 mg/kg/day caused evidence of toxicity in pregnant rabbits but did not produce evidence of embryo or fetal toxicity. lsopropanol did not produce an increased incidence of malformations (teratogenicity) in either species. An indication of reduced mating performance in 2nd generation male rats was noted at oral doses of 1000 mg/kg/day in a two-generation reproductive study. Increased neonatal mortality was also seen at doses of 500 mg/kg/day and greater in this study. No evidence of neurotoxic effects was observed in studies specifically designed to assess neurobehavioral functions in neonatal rats after oral dosing of mothers during gestation and lactation. In an acute vapor inhalation study, high concentrations of lsopropanol (1500 ppm and greater) caused a spectrum of transient effects indicative of narcosis. In repeated inhalation exposure studies, high vapor concentrations (5000 ppm) produced an increase in motor activity in rats first noted after 4 weeks of exposure. The effect was reversible completely resolving within 14 days after 13 weeks of exposure. No evidence of damage to nerve tissue was seen in this study. Lifetime exposure of laboratory animals to high concentrations of lsopropanol vapor (greater than 1500 ppm) exacerbated chronic progressive nephropathy commonly seen in aged animals. The relevance of this finding to human health hazard evaluation is unknown. No evidence suggestive of carcinogenic activity was noted in chronic vapor inhalation studies with lsopropanol in rats and mice.
