HAZARDS IDENTIFICATIONS
EMERGENCY OVERVIEW:
APPEARANCE: Light Blue
PHYSICAL STATE: Liquid
ODOR: Mild
HAZARDS OF PRODUCT: No significant immediate hazards for emergency response are known.
POTENTIAL HEALTH EFFECTS:
EFFECTS OF SINGLE ACUTE OVEREXPOSURE
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 the skin. Repeated contact may cause flaking and
softening of skin.
SKIN ABSORPTION: Prolonged skin contact is unlikely to result in absorption of harmful amounts.
INGESTION: Very low toxicity if swallowed. Harmful effects not anticipated from swallowing small amounts.
CHRONIC, PROLONGED OR REPEATED OVEREXPOSURE
EFFECTS OF REPEATED OVEREXPOSURE: In rare cases, repeated excessive exposure to propylene glycol may cause
central nervous system effects.
OTHER EFFECTS OF OVEREXPOSURE: No information currently available.

FIRST AID MEASURES
INHALATION: Move person to fresh air; if effects occur, consult a physician.
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.
SKIN CONTACT: Wash skin with plenty of water.
INGESTION: No emergency medical treatment necessary.
ADVICE TO No specific antidote. Treatment of exposure should be directed at the control of symptoms and the clinical
PHYSICIANS: condition of the patient.
FIRE FIGHTING MEASURES
FLAMMABLE PROPERTIES:
REFER TO PHYSICAL AND CHEMICAL PROPERTIES SECTION
EXTINGUISHING MEDIA: Water fog of fine spray. Dry chemical & 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.
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 the
product can burn. Flammable concentrations of vapor can accumulate at temperatures
above flash point.
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 re-ignition 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.
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.
HAZARDOUS COMBUSTION
PRODUCTS: 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.
ACCIDENTAL RELEASE MEASURES
IN CASE OF SPILL OR OTHER RELEASE:
Small spills: Absorb with materials such as--cat litter, sawdust, vermiculite. Collect in suitable and properly
labeled container.
Large spills: Dike area to contain spill. Recover spilled material if possible. See Disposal Considerations section
for additional information.
PERSONAL PRECAUTIONS: Use appropriate safety equipment. For additional information, refer to Exposure Controls
and Personal Protection section.
ENVIRONMENTAL PRECAUTIONS: Prevent from entering into soil, ditches, sewers, waterways and/or groundwater. See
Ecological Information section.

HANDLING AND STORAGE
HANDLING: (Always wear recommended personal protective equipment)
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 auto-
ignition temperatures possibly resulting in spontaneous combustion.
STORAGE: Store below: 121 deg. C (250 deg. F). Do not store in: galvanized steel.
EXPOSURE CONTROLS/PERSONAL PROTECTION
EXPOSURE GUIDELINES
INGREDIENT NAME ACGIH TLV OSHA PEL OTHER LIMIT SKIN. FORM
Propylene glycol NA NA 10 mg/m3 TWA 8 AIHA WEEL
In the Exposure Limits Chart above, if there is no specific qualifier (i.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 cutaneous (skin) route,
including mucous membranes and the eyes, either by contact with vapors or by direct skin contact with the substances. A
"Blank" in the Skin Column indicates that exposure by the cutaneous (skin) route is not a potential significant contributor to
overall exposure.
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 and approved particulate respirator.
Ventilation: Provide general and/or local exhaust ventilation to control airborne levels below the
exposure guidelines.
Eye Protection: Use safety glasses.
Other Protective
Equipment: No precautions other than clean body-covering clothing should be needed. Use gloves
chemically resistant to this material.
