Risk Phrases: 11 38 50/53 65 67
Section 3 - Hazards
Appearance: clear, colorless liquid. Flash Point: -4 deg C. Aspiration hazard
if swallowed. Can enter lungs and cause damage.
Warning! Flammable liquid and vapor. Breathing
vapors may cause drowsiness and dizziness. Dangerous for the environment. Causes
eye, skin, and respiratory tract irritation.
Central nervous system, lungs, eyes, skin.
Potential Health Effects
Eye: Causes eye irritation.
Skin: Causes skin irritation. Prolonged and/or repeated
contact may cause defatting of the skin and dermatitis.
Ingestion: Causes gastrointestinal irritation with nausea,
vomiting and diarrhea. 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
Chronic: Prolonged or repeated skin contact may
Section 4 - First Aid
Eyes: Flush eyes with plenty of water for at least
15 minutes, occasionally lifting the upper and lower eyelids. Get medical aid
Skin: Get medical aid. Flush skin with plenty
of water for at least 15 minutes while removing contaminated clothing and shoes.
Wash clothing before reuse.
Ingestion: Potential for
aspiration if swallowed. Get medical aid immediately. Do not induce vomiting
unless directed to do so by medical personnel. Never give anything by mouth to
an unconscious person.
Inhalation: Get medical aid
immediately. Remove from exposure and move to fresh air immediately. If not
breathing, give artificial respiration. If breathing is difficult, give oxygen.
Do NOT use mouth-to-mouth resuscitation.
Physician: Treat symptomatically and supportively.
Section 5 - Fire
Information: As in any fire, wear a self-contained breathing apparatus
in pressure-demand, MSHA/NIOSH (approved or equivalent), and full protective
gear. Use water spray to keep fire-exposed containers cool. Flammable liquid and
vapor. Vapors are heavier than air and may travel to a source of ignition and
flash back. Vapors can spread along the ground and collect in low or confined
areas. This liquid floats on water and may travel to a source of ignition and
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. Water may be
ineffective. Do NOT use straight streams of water.

Section 6 -
Accidental Release Measures
Information: Use proper personal protective equipment as indicated in
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
Handling: Wash thoroughly after handling. Remove
contaminated clothing and wash before reuse. Ground and bond containers when
transferring material. Use spark-proof tools and explosion proof equipment.
Avoid contact with eyes, skin, and clothing. Empty containers retain product
residue, (liquid and/or vapor), and can be dangerous. Do not pressurize, cut,
weld, braze, solder, drill, grind, or expose empty containers to heat, sparks or
open flames. Use only with adequate ventilation. Keep away from heat, sparks and
flame. Avoid breathing vapor.
Storage: 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
Controls: 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
