EMERGENCY OVERVIEW
Appearance: colorless liquid. Flash Point: -37 deg C.
Danger! Extremely flammable
liquid. May cause reproductive and fetal effects.
Potential cancer hazard. Causes severe eye and skin irritation with
possible burns. Harmful if swallowed. May be harmful if absorbed
through the skin. May cause allergic skin reaction. Causes
respiratory tract irritation.
Target Organs: Central nervous system,
respiratory system, eyes, skin.
Potential Health Effects
Eye:
Produces irritation, characterized by a burning sensation, redness,
tearing, inflammation, and possible corneal injury.
Skin:
May cause skin sensitization, an allergic reaction, which becomes
evident upon re-exposure to this material. Causes severe skin
irritation and possible burns. May lead to the formation of
blisters.
Ingestion:
Harmful if swallowed. Causes gastrointestinal irritation with
nausea, vomiting and diarrhea. May cause central nervous system
depression, characterized by excitement, followed by headache,
dizziness, drowsiness, and nausea. Advanced stages may cause
collapse, unconsciousness, coma and possible death due to respiratory
failure. Aspiration of material into the lungs may cause chemical
pneumonitis, which may be fatal.
Inhalation:
Inhalation of high concentrations may cause central nervous system
effects characterized by nausea, headache, dizziness, unconsciousness
and coma. Causes respiratory tract irritation. Aspiration may cause
respiratory swelling and pneumonitis. Vapors may cause dizziness or
suffocation.
Chronic:
Prolonged inhalation may cause respiratory tract inflammation and
lung damage. Prolonged or repeated skin contact may cause
dermatitis. May cause cancer according to animal studies. May cause
reproductive and fetal effects. Laboratory experiments have resulted
in mutagenic effects.
May cause heritable genetic damage.
Section 4 - First Aid Measures
|
Eyes:
Immediately flush eyes with plenty of water for at least 15 minutes,
occasionally lifting the upper and lower eyelids. Get medical aid
immediately.
Skin:
Get medical aid immediately. Immediately flush skin with plenty of
water for at least 15 minutes while removing contaminated clothing
and shoes. Wash clothing before reuse.
Ingestion:
Do NOT induce vomiting. If victim is conscious and alert, give 2-4
cupfuls of milk or water. Never give anything by mouth to an
unconscious person. Possible aspiration hazard. Get medical aid
immediately.
Inhalation:
Get medical aid immediately. Remove from exposure and move to fresh
air immediately. If breathing is difficult, give oxygen. Do NOT use
mouth-to-mouth resuscitation. If breathing has ceased apply
artificial respiration using oxygen and a suitable mechanical device
such as a bag and a mask.
Notes to Physician:
Persons with kidney disease, chronic respiratory disease, liver
disease, or skin disease may be at increased risk from exposure to
this substance. Treat symptomatically and supportively.
Section 5 - Fire Fighting Measures
|
General Information:
Containers can build up pressure if exposed to heat and/or fire. As
in any fire, wear a self-contained breathing apparatus in
pressure-demand, MSHA/NIOSH (approved or equivalent), and full
protective gear. Vapors may form an explosive mixture with air.
Vapors can travel to a source of ignition and flash back. Extremely
flammable. Material will readily ignite at room temperature. Use
water spray to keep fire-exposed containers cool. Containers may
explode in the heat of a fire. Liquid will float and may reignite on
the surface of water. May polymerize explosively when involved in a
fire.
Extinguishing Media:
For small fires, use dry chemical, carbon dioxide, water spray or
alcohol-resistant foam. For large fires, use water spray, fog, or
alcohol-resistant foam. Use water spray to cool fire-exposed
containers. Water may be ineffective. Do NOT use straight streams of
water.
Flash Point: -37 deg C ( -34.60 deg F)
Autoignition Temperature: 449 deg C ( 840.20 deg F)
Explosion Limits, Lower:2.3 vol %
Upper: 36.0 vol %
NFPA Rating:
(estimated) Health: 3; Flammability: 4; Instability: 2
Section 6 - Accidental Release Measures
|
General Information: Use proper personal protective equipment as indicated
in Section 8.
Spills/Leaks:
Absorb spill with inert material (e.g. vermiculite, sand or earth),
then place in suitable container. Avoid runoff into storm sewers and
ditches which lead to waterways. Clean up spills immediately,
observing precautions in the Protective Equipment section. Remove all
sources of ignition. Use a spark-proof tool. Provide ventilation. A
vapor suppressing foam may be used to reduce vapors.
Section 7 - Handling and Storage
|
Handling:
Wash thoroughly after handling. Remove contaminated clothing and
wash before reuse. Use only in a well-ventilated area. Ground and
bond containers when transferring material. Empty containers retain
product residue, (liquid and/or vapor), and can be dangerous. Avoid
contact with heat, sparks and flame. Do not get on skin or in eyes.
Do not ingest or inhale. Prevent build up of vapors to explosive
concentration. This product may be under pressure; cool before
opening. Do not pressurize, cut, weld, braze, solder, drill, grind,
or expose empty containers to heat, sparks or open flames.
Storage:
Keep away from heat, sparks, and flame. Keep away from sources of
ignition. Store in a tightly closed container. Store in a cool, dry,
well-ventilated area away from incompatible substances.
Flammables-area.
Section 8 - Exposure Controls, Personal Protection
|
Engineering Controls:
Use explosion-proof ventilation equipment. Facilities storing or
utilizing this material should be equipped with an eyewash facility
and a safety shower. Use adequate general or local exhaust
ventilation to keep airborne concentrations below the permissible
exposure limits.

If released to soil, propylene oxide is expected to be susceptible to
leaching and chemical hydrolysis in moist soils. It is expected to
evaporate relatively rapidly from dry soil surfaces; evaporation
from wet soils may also occur, but at a rate diminished by leaching.
If released to water, propylene oxide will hydrolyze. Volatilization
of propylene oxide from the aquatic environment may be an important
transport mechanism.
Environmental:
If released to the atmosphere, propylene oxide will react in the
vapor phase with photochemically produced hydroxyl radicals with an
estimated half-life of approximately 30 days. Atmospheric removal by
rainfall may occur. Adsorption to sediment, bioconcentration in
aquatic organisms and reaction with photochemically produced hydroxyl
radicals in water are not expected to be environmentally important
fate processes.
Physical:
No information available.
Other:
No information available.
Section 13 - Disposal Considerations
|
