IDENTIFICATION:
CAS:
108-05-4
DOT ID:
UN1301
Hazard Class or Division:
3 (FLAMMABLE LIQUID)
ERG Guide:
129P
Formula:
C4H6O2
RTECS No:
AK0875000
Properties:
Extremely
flammable, clear, colorless liquid. Pleasant, fruity odor, becoming sharp and
irritating. Soluble in water to 2%; the rest floats. Vapors are heavier than
air; will collect in low areas.

industrial glues, paints and coatings.
HEALTH & SAFETY INFORMATION
• IARC:
Group
3, not classifiable as to carcinogenicity to humans; inadequate animal and
human evidence. The International Agency for Research on Cancer has determined
that vinyl acetate is not classifiable as to its carcinogenicity to humans.
• Odor threshold:
0.42 mg/m3. The ability to recognize the characteristic odor may
be lost after about 2 hours of exposure.
•
OSHA Table Z-1 Air Contaminant
• NIOSH Criteria Document
: NIOSH 78-205
•
High levels are irritating to eyes, skin, nose and lungs; prolonged contact
with skin can cause burns and blisters. It is unknown what happens if vinyl
acetate is ingested. Long term exposure may cause irritation, of the eyes,
throat, and lungs, sometime accompanied by skin irritation or rash. Chronic
exposure may cause lung damage.
Animal
studies:
Long-term studies
show a reduced ability of animals to fight infection when rats and mice
ingested high levels of the chemical. Birth defects were not seen in the
offspring of animals that were exposed to vinyl acetate in drinking water during
their pregnancies.
Exposure Limits:
•
ACGIH TLV: 10 ppm TWA; 15 ppm STEL, confirmed animal carcinogen with unknown
relevance to humans
•
OSHA PEL: None established
•

Note:
Substance reported to cause
eye irritation or damage; may require eye protection.
Reactivity:
Forms
explosive mixture with air. Polymerizes readily if not inhibited [usually
hydroquinone (< 60 days) or diphenylamine (60 days or more)]; heat can
initiate reaction. Reacts violently with oxidizers, strong acids, bases, and
peroxides. Incompatible with acids, ammonia, aliphatic amines, and
alkanolamines. Also reacts with 2-aminoethanol, chlorosulfonic acid, ethylene
diamine, ethyeneimine, ozone, and oleum. May accumulate static electrical
charges, and may cause ignition of its vapors.
FIRE INFORMATION:
Vapors may travel long distances to ignition sources and flash
back. Containers or vapors in confined areas may explode in fire. If material
or contaminated runoff enters waterways, notify downstream users of potentially
contaminated water.

FIRST AID:
Move
victim to fresh air. Call emergency medical care. Apply artificial respiration
if victim is not breathing. Administer oxygen if breathing is difficult. Remove
and isolate contaminated clothing and shoes. In case of contact with substance,
immediately flush skin or eyes with running water for at least 20 minutes. Wash
skin with soap and water. Keep victim warm and quiet. Effects of exposure
(inhalation, ingestion or skin contact) to substance may be delayed. Ensure
that medical personnel are aware of the material(s) involved, and take
precautions to protect themselves.
