4. First-Aid Measures

Eye Contact Wash eyes immediately with large amounts of water or normal saline,
occasionally lifting upper and lower lids, until no evidence of chemical
remains (at least 15-20 minutes). Get medical attention immediately.

Skin Contact Remove contaminated clothing and shoes. Wash with soap or mild
detergent and large amounts of water until no evidence of chemical
remains (at least 15-20 minutes).

Inhalation No expected to present a significant inhalation hazard under anticipated

conditions of normal use.

Ingestion Treat symptomatically and supportively.

Note to physician No specific antidote. Treat symptomatically and supportively.

5. Fire-Fighting Measures

Fire and Explosion Hazard Slight fire hazard when exposed to heat or flame. Heat from
fire can generate flammable vapor. When mixed with air and
exposed to ignition source, vapor can burn in open or
explode if confined. Vapors may travel long distances along
the ground before igniting and flashing back to vapor source.
Fine sprays/mists may be combustible at temperatures below
normal flash point. Aqueous solutions containing less than
 95% propylene glycol by weight have no flash point as
obtained by standard test methods. However aqueous
solutions of propylene glycol greater than 22% by weight, if
heated sufficiently, will produce flammable vapor. Only
aqueous solutions of propylene glycol less than 22% should
used in sprinkler systems or other fire-fighting equipment.
Always drain and flush systems containing propylene glycol
with water before welding or other maintenance.

Extinguishing Media Dry chemical, carbon dioxide, water spray or

alcohol-resistant foam. For larger fires, use water spray, fog
or alcohol-resistant foam. Alcohol foam.

Firefighting Move container from fire area if you can do it without risk. Do
not enter fire area without proper protection. Fight fire from a
safe distance/protected location. Heat may build enough
pressure to rupture closed container/spreading
fire/increasing risk of burns/injuries. Use water spray/fog for
cooling. Avoid frothing/steam explosion. Do not scatter
spilled material with high-pressure water streams. Burning
liquid may float on water. Although water soluble, may not be
practical to extinguish fire by water dilution. Dike fire-control
water for later disposal. Avoid breathing hazardous vapors,
keep upwind. Notify authorities immediately if liquid enters
sewer/public waters.

Flash Point 210 F (99 C) (CC)

Lower Flammable Limit 2.6%

Upper Flammable Limit 12.5%

Autoignition 700 F (371 C)

Flammability Class (OSHA) II1B

Hazardous Combustion Products Thermal decomposition products may include toxic oxides of
carbon.

6. Accidental Release Measures

Occupational spill May contaminate water supplies/pollute public waters. Evacuate/limit

access. Equip responders with proper protection. Prevent flow to
sewer/public waters. Stop release. Notift fire and environmental
authorities. Restrict water use for cleanup. Slippery walking. Spread
 granular cover. Impound/recover large land spill. Soak up small spills
with inert solids. Use suitable disposal containers. On water, material is
soluble and may float or sink. May biodegrade. Contain/collect rapidly
to minimize dispersion. Disperse residue to reduce aquatic harm.
Report per regulatory requirements. Keep unnecessary people away;
isolate hazard area and restrict entry.

7. Handling and Storage

Handling Hygroscopic. Use dry nitrogen or low dew point air for tank padding. Keep
drums tightly closed to prevent contamination.

Storage Store at 18-32 C. store away from incompatible substances.

8. Material condition / Personal Protection

Product condition Liquid

Exposure Limits No occupational exposure limits established by OSHA, ACGIH, or

NIOSH.

Ventilation No special ventilation is recommended under anticipated conditions of

normal use beyond that needed for normal comfort control.

Eye Protection Employee wear splash-proof or dust-resistant safety goggles to

prevent eye contact with this substance.

Emergency eye wash: Where there is any possibility that an

employee’s eyes may be exposed to this substance; the employer
should provide an eye wash fountain within the immediate work area
for emergency use.

Skin Protection Not normally considered a skin hazard. Where use can result in skin
contact, practice good personal hygiene. Wash hands and other
exposed areas with mild soap and water before eating, drinking,
smoking and when leaving work.

Respirator No special respirator protection is recommended under anticipated

conditions of normal use with adequate ventilation.
