Remove the victim to fresh air, and make him blow his nose andgargle.

First-aid measures after skincontact:

Wash the affected areas under running water.

First-aid measures after eye
contact:

Wash the affected areas under running water for at least 15
minutes. If necessary, get medical treatment.

First-aid measures afteringestion:

The chemical is volatile. Do not induce vomiting because it
increases the risk of aspiration into the lungs. Get medicalattention immediately. If necessary, rinse mouth with water.

Personal Protection in FirstAid and Measures:

Rescuers should wear proper protective equipment like rubber
gloves, goggles.

5. Fire fighting measures
Suitable extinguishing media:

Water, dry chemical powder, carbon dioxide, dry sand, alcohol
resistant foam

Unsuitable extinguishing media:

Foam extinguisher

Firefighting instructions:

Move containers from fire area if it can be done without risk, if
not possible, apply water from a safe distance to cool andprotect surrounding area.
Fight fire from windward.
Dry chemical powder, carbon dioxide or dry sand should be used
for small fires. Alcohol-resistant foam extinguisher is effective
for a large scale fire.

Personal protection (Emergencyresponse):

Wear breathing apparatus.

6. Accidental release measures
Personal Precautions, Protective Equipment and Emergency Procedures
General measures:

Wear proper protective equipment and avoid contact with skin andinhalation of vapor. Conduct operations from upwind and evacuate
people downwind. Keep away personnel except for authorized ones
from spillage area by stretching ropes.

:

Attention should be given to avoid discharge of spilled productinto rivers and resulting environmental damage. When diluting
spill with large amounts of water, discharge of untreatedwastewater into the environment must be avoided.

Environmental precautions
Environmental precautions

Methods and Equipment for Containment and Cleaning up
For containment:

Absorb spill with inert material （e.g, diatomaceous earth,sand） and flush spillage area with copious amounts of water.

Prevention Measures for
Secondary Accidents:

Remove nearby sources of ignition and prepare extinguishingmedia.

:

Wear proper protective equipment to avoid contact with skin or
inhalation of vapor. Fire is strictly prohibited.

7. Handling and storage
Handling
Technical measures

Ventilate well at working places.
Prevent build-up of electrostatic charges （e.g. by grounding）.
Precautions for safe handling:

Use with an enclosed system or a local exhaust ventilation. Use
in well-ventilated areas.
Do not allow contact with oxidizing substances.

Storage
Storage conditions:

Store in a dark, cool place and tightly closed.

Material used inpackaging/containers:

Glass, stainless steel.
Do not use vinyl chloride resin, acrylic resin, polystyrene etc.

Acute toxicity (oral)
Acute toxicity (dermal)
Acute toxicity (inhalation): No classification
rat LD50>5000mg/kg: No classification
rabbit LD50>5000mg/kg: No classification (gas)No classification (vapor)
Classification not possible (dust, mist): rat LC50=32000ppm/4h

Acute toxicity (vapor) Description
Skin corrosion/irritation:Serious eye damage/irritation:

Respiratory sensitization
Skin sensitization::

Germ cell mutagenicity:

Carcinogenicity:

Reproductive toxicity:

STOT-single exposure:

No classification
Acetone has no irritation to rabbit skin.
Causes eye irritation
Vapor stimulates human eye. However, if exposure stops, irritation
will not follow. The result of severe is reported in the rabbit.
Although a corneal epithelium is destroyed, substrate is notdestroyed, and destruction of a corneal epithelium will berecovered in 4-6 days. Since acetone is not corrosive eyeirritations, it was classified into category 2B.
Classification not possible
No classification
There was observed no skin sensitization in Maximization test using
guinea pig.
No classification
Acetone is negative in vivo micronucleus examination.
No classification
ACGIH classifies it as the group A4(not classifiable as a humancarcinogen).
Suspected of damaging fertility or the unborn child
Acetone is describe that it has no effect on abortion by theepidemiologic investigation. But high concentration exposure ofacetone for rats (11000ppm (20mg/L)), caused weak developmental
toxicity that is decrease in embryonic weight, high concentration
exposure of acetone for mice (6600ppm (15.6mg/L)), caused decreasein embryonic weight, later embryo absorption rate. From the above,it was classified into category 2.
May cause drowsiness or dizziness
May cause respiratory irritation
Based on the descriptions of acetone that irritation in the humanthroat is caused by 12000ppm exposure, that irritation is caused in
the nasal cavity, throat and trachea by 1190 and 2400mg/m3/6h
exposure to humans, and that irritation was caused in the throat by
1000ppm/4h exposure. Thus, it was classified into category 3(respiratory tract irritation). From the description that a man whoswallowed 200mL of the substance progressed to coma (recovery ofconsciousness after 12 hours), and a worker who was exposed vaporof 12000ppm suffered from headache, dizziness, weakness of legs,
unconsciousness, it was classified into category 3 (narcosis).

STOT-repeated exposure:

Causes damage to organs (central nervou system, respiratory organs,digestive tract) through prolonged or repeated exposureIn humans, there is the description that inflammation was observedin respiratory, stomach and duodenum with dizziness, weakness as
the effects of occupational exposure, in worker who was inhalation
exposure to 700 ppm of this substance, 3 hours/day for 7 to 15
years. Based on the above mention, it was classified into category1(central nervous system, respiratory organs, digestive tract).

Aspiration hazard:

Classification not possible
The calculated dynamic viscosity is 0.426mm2/sec and aceton is aketone of under C13, however, there was not the animal data ofchemical pneumonia, it was not possible to classify because ofinsufficient data.
