Consult a physician. Show this safety data sheet to the doctor in attendance.If inhaled
Fresh air, rest. Refer for medical attention.In case of skin contact
Rinse contaminated clothes (fire hazard) with plenty of water. Remove contaminated clothes. Rinse skin with plenty of water or shower.In case of eye contact
First rinse with plenty of water for several minutes (remove contact lenses if easily possible), then refer for medical attention.If swallowed
Rinse mouth. Give one or two glasses of water to drink. Refer for medical attention .4.2 Most important symptoms/effects, acute and delayed
(Very similar to those of methyl alcohol, which constitutes 20% of commercial grade.) Inhalation causes headache, fatigue, and drowsiness; high concentrations can produce central nervous system depression and optic nerve damage. Liquid irritates eyes and may cause defatting and cracking of skin. Ingestion causes headache, dizziness, drowsiness, fatigue; may cause severe eye damage. (USCG, 1999)4.3 Indication of immediate medical attention and special treatment needed, if necessary
Immediate first aid: Ensure that adequate decontamination has been carried out. If patient is not breathing, start artificial respiration, preferably with a demand-valve resuscitator, bag-valve-mask device, or pocket mask, as trained. Perform CPR as necessary. Immediately flush contaminated eyes with gently flowing water. Do not induce vomiting. If vomiting occurs, lean patient forward or place on left side (head-down position, if possible) to maintain an open airway and prevent aspiration. Keep patient quiet and maintain normal body temperature. Obtain medical attention. /Methyl alcohol and related compounds/5.Fire-fighting measures 5.1 Extinguishing media Suitable extinguishing media
Suitable extinguishing media: Use water spray, alcohol-resistant foam, dry chemical or carbon dioxide.5.2 Specific hazards arising from the chemical
Behavior in Fire: Vapor is heavier than air and may travel a considerable distance to a source of ignition and flash back. (USCG, 1999)5.3 Special protective actions for fire-fighters
Wear self-contained breathing apparatus for firefighting if necessary.6.Accidental release measures 6.1 Personal precautions, protective equipment and emergency procedures
Use personal protective equipment. Avoid dust formation. Avoid breathing vapours, mist or gas. Ensure adequate ventilation. Evacuate personnel to safe areas. Avoid breathing dust. For personal protection see section 8.6.2 Environmental precautions
Remove all ignition sources. Evacuate danger area! Consult an expert! Personal protection: filter respirator for organic gases and vapours of low boiling point adapted to the airborne concentration of the substance. Do NOT wash away into sewer. Collect leaking liquid in sealable containers. Absorb liquid in sand or inert absorbent. Then store and dispose of according to local regulations.6.3 Methods and materials for containment and cleaning up
Remove all ignition sources. Establish forced ventilation to keep levels below explosive limit. Absorb liquids in vermiculite, dry sand, earth, peat, carbon or a similar materail and deposit in sealed containers. Keep this chemical out of a confined space, such as a sewer, because of the possibility of an explosion.7.Handling and storage 7.1 Precautions for safe handling
Avoid contact with skin and eyes. Avoid formation of dust and aerosols. Avoid exposure - obtain special instructions before use.Provide appropriate exhaust ventilation at places where dust is formed. For precautions see section 184.108.40.206 Conditions for safe storage, including any incompatibilities
Fireproof. Separated from strong oxidants, strong acids and strong bases.Store in a flammable liquid storage area or approved cabinet away from ignition sources and corrosive and reactive materials. ... Methyl acetate must be stored to avoid contact with strong oxidizers (such as chlorine, bromine, and fluorine) and strong acids (such as hydrochloric, sulfuric, and nitric), since violent reactions occur. Store in tightly closed containers in a cool, well-ventilated area away from strong alkalis and nitrates. Sources of ignition, such as smoking and open flames, are prohibited where methyl acetate is used, handled or stored in a manner that could create a potential fire or explosion hazard. Use only nonsparking tools and equipment, especially when opening and closing containers of methyl acetate.8.Exposure controls/personal protection 8.1 Control parameters Occupational Exposure limit values

no data available8.2 Appropriate engineering controls
Handle in accordance with good industrial hygiene and safety practice. Wash hands before breaks and at the end of workday.8.3 Individual protection measures, such as personal protective equipment (PPE) Eye/face protection
Safety glasses with side-shields conforming to EN166. Use equipment for eye protection tested and approved under appropriate government standards such as NIOSH (US) or EN 166(EU).Skin protection
Wear impervious clothing. The type of protective equipment must be selected according to the concentration and amount of the dangerous substance at the specific workplace. Handle with gloves. Gloves must be inspected prior to use. Use proper glove removal technique(without touching glove's outer surface) to avoid skin contact with this product. Dispose of contaminated gloves after use in accordance with applicable laws and good laboratory practices. Wash and dry hands. The selected protective gloves have to satisfy the specifications of EU Directive 89/686/EEC and the standard EN 374 derived from it.Respiratory protection
Wear dust mask when handling large quantities.Thermal hazards

AEROBIC: Methyl acetate achieved >70% after 28 days in an OECD 301D Closed bottle test(1). Methyl acetate reached > 95% degradation in a 5 day BOD test(2).12.3 Bioaccumulative potential
An estimated BCF of 3.2 was calculated in fish for methyl acetate(SRC), using a log Kow of 0.18(1) and a regression-derived equation(2). According to a classification scheme(3), this BCF suggests the potential for bioconcentration in aquatic organisms is low(SRC).12.4 Mobility in soil
The Koc of methyl acetate is estimated as 9.1(SRC), using a log Kow of 0.18(1) and a regression-derived equation(2). According to a classification scheme(3), this estimated Koc value suggests that methyl acetate is expected to have very high mobility in soil(SRC).12.5 Other adverse effects
