Wash the affected areas under running water, get medical
treatment as soon as possible.

First-aid measures after eye
contact:

Wash the affected areas under running water for at least 15
minutes. Get medical treatment.

Rinse mouth with water. Give the victim one or two glasses ofwater or milk. Do not induce vomiting. Get medical treatment assoon as possible.

Personal Protection in FirstAid and Measures:

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

Suitable extinguishing media:

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

Unsuitable extinguishing media:

protect 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):

Firefighters should wear protective equipment.

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. Remove all sources of ignition. 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 forSecondary Accidents:

Remove nearby sources of ignition and prepare extinguishingmedia.

:

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

7. Handling and storage
Handling
Technical measures

Ventilate well at working places.
:

Use with an enclosed system or a local exhaust ventilation. Use
in well-ventilated areas.

Storage conditions:

Store in a dark, cool place and tightly closed.

Aspiration hazard::

Causes severe skin burns
In tests with rabbits and guinea pigs, the degree of irritation
depended on the application concentrations and exposure periods.
Concentrations from 50 - 80% produced severe burns and eschar
formation.Based on these data, the product was classified into
category 1B.
Causes serious eye damage
Glacial acetic acid causes devastating injury immediately after
application to the eyes of rabbits. In another rabbit test,
concentrations of 10% and higher produced severe irritation withpermanent corneal damage. Additionally, there is a case report that
accidental application to the eyes followed very quickly byirrigation resulted in corneal opacity and iritis. Regeneration of
the epithelium took many months, but corneal opacity was permanent.
Based on these data, the product was classified into category 1.
Classification not possible
Classification not possible
Classification not possible
Classification is not possible because an available datum is only
negative on in vitro mutagenicity study.
Classification not possible
Classification not possible
Causes damage to organs (blood, respiratory organs)
Based on case reports that ingestion of glacial acetic acid orlarge amount of acetic acid in humans caused disseminatedintravascular coagulation, severe hemolysis and ischemic renal
failure, acetic acid is rated as category 1 (blood). And based onhuman evidence including "inhalation exposure caused irritation in
nose, upper respiratory tract and lung", "vapor inhalation produced
respiratory tract corrosion and pulmonary edema" and "exposure due
to accident at petrochemical plant caused airway obstruction andinterstitial pneumonia", acetic acid is rated as category 1(respiratory organs).
