3. HAZARDS IDENTIFICATION

3.1 EMERGENCY OVERVIEW

-Appearance: Dyed Yellow

-Physical State: Liquid

-Odor: Mild

-Hazards of product: NO SIGNIFICANT IMMEDIATE HAZARDS FOR EMERGENCY RESPONSE ARE KNOWN.

3.2 POTENTIAL HEALTH EFFECTS

-Potential Effects of a Single Acute Exposure Inhalation At room temperature, exposure to vapor is minimal due to low volatility. Mist may

cause irritation of upper respiratory tract (nose and throat). Eye Contact May cause slight temporary eye irritation. Corneal injury is unlikely. Skin Contact Prolonged contact is essentially nonirritating to skin. Repeated contact may cause flaking and softening of skin. Skin Absorption Prolonged skin contact is unlikely to result in absorption of harmful amounts. Swallowing Very low toxicity if swallowed. Harmful effects not anticipated from swallowing small amounts. Chronic, Prolonged or Repeated Exposure Potential Effects of Repeated Exposure In rare cases, repeated excessive exposure to propylene glycol may cause central nervous system effects.

3.3 POTENTIAL ENVIRONMENTAL EFFECTS

See Section 12 for Ecological Information.

4. FIRST AID PROCEDURES

4.1 INHALATION

-Move person to fresh air; if effects occur, consult a physician.

4.2 EYE CONTACT

-Flush eyes thoroughly with water for several minutes. Remove contact lenses after the initial 1-2 minutes and continue flushing for several additional minutes. If effects occur, consult a physician, preferably an ophthalmologist.

4.3 SKIN CONTACT

-Wash skin with plenty of water.

4.4 SWALLOWING

-No emergency medical treatment necessary.

4.5 NOTES TO PHYSICIAN

-No specific antidote. Treatment of exposure should be directed at the control of symptoms and the clinical condition of the patient.

5. FIRE FIGHTING MEASURES

5.1 FLAMMABLE PROPERTIES - REFER TO SECTION 9, PHYSICAL AND CHEMICAL PROPERTIES

5.2 EXTINGUISHING MEDIA

-Water fog or fine spray. Dry chemical fire extinguishers. Carbon dioxide fire extinguishers.

-Foam. Do not use direct water stream. May spread fire. Alcohol resistant foams (ATC type) are preferred. General purpose synthetic foams (including AFFF) or protein foams may function, but will be less effective.

5.3 FIRE FIGHTING PROCEDURES

-Keep people away. Isolate fire and deny unnecessary entry. Use water spray to cool fire exposed containers and fire affected zone until fire is out and danger of reignition has passed.

-Fight fire from protected location or safe distance. Consider the use of unmanned hose holders or monitor nozzles. Immediately withdraw all personnel from the area in case of rising sound from venting safety device or discoloration of the container. Burning liquids may be extinguished

by dilution with water. Do not use direct water stream. May spread fire. Move container from fire area if this is possible without hazard. Burning liquids may be moved by flushing with water to protect personnel and minimize property damage.

5.4 SPECIAL PROTECTIVE EQUIPMENT FOR FIREFIGHTERS

-Wear positive-pressure self-contained breathing apparatus (SCBA) and protective fire fighting clothing (includes fire fighting helmet, coat, pants, boots, and gloves). If protective equipment is not available or not used, fight fire from a protected location or safe distance.

5.5 UNUSUAL FIRE AND EXPLOSION HAZARDS

-Container may rupture from gas generation in a fire situation.

-Violent steam generation or eruption may occur upon application of direct water stream to hot liquids.

-Liquid mist of this product can burn.

-Flammable concentrations of vapor can accumulate at temperatures above flash point; see Section 9.

-During a fire, smoke may contain the original material in addition to combustion products of varying composition which may be toxic and/or irritating. Combustion products may include and are not limited to: Carbon monoxide. Carbon dioxide.

6. ACCIDENTAL RELEASE MEASURES

-Steps to be Taken if Material is Released or Spilled:

Small spills: Absorb with materials such as: Cat litter. Sawdust. Vermiculite. Zorb-all®. Collect in suitable and properly labeled containers. Large spills: Dike area to contain spill. Recover spilled material if possible. See Section 13, Disposal Considerations, for additional information.

-Personal Precautions: Use appropriate safety equipment. For additional information, refer to Section 8, Exposure Controls and Personal Protection.

Environmental Precautions: Prevent from entering into soil, ditches, sewers, waterways and/ or groundwater. See Section 12, Ecological Information.

7. HANDLING AND STORAGE

7.1 HANDLING

General Handling

See Section 8, EXPOSURE CONTROLS AND PERSONAL PROTECTION.

-Ventilation: Provide general and/or local exhaust ventilation to control airborne levels below the exposure guidelines.

-Other Precautions: Spills of these organic materials on hot fibrous insulations may lead to lowering of the autoignition temperatures possibly resulting in spontaneous combustion.

7.2 STORAGE

8.2 PERSONAL PROTECTION

-Respiratory Protection: Atmospheric levels should be maintained below the exposure guideline. When respiratory protection is required for certain

operations, use an approved air-purifying respirator. In dusty or misty atmospheres, use an approved particulate respirator.

-Ventilation: Provide general and/or local exhaust ventilation to controlairborne levels below the exposure guidelines.

-Eye Protection: Use safety glasses.
