Section 4 - First Aid Measures
|
Eyes:
Immediately flush eyes with plenty of water for at least 15 minutes,
occasionally lifting the upper and lower eyelids. Get medical aid imme
diately.
Skin:
Get medical aid. Immediately flush skin with plenty of water for at
least 15 minutes while removing contaminated clothing and shoes.
Wash clothing before reuse.
Ingestion:
If victim is conscious and alert, give 2-4 cupfuls of milk or water.
Never give anything by mouth to an unconscious person. Get medical
aid immediately.

breathing, give artificial respiration. If breathing is difficult,
give oxygen. Get medical aid.
Notes to Physician:
Treat symptomatically and supportively.
Section 5 - Fire Fighting Measures
|
General Information:
As in any fire, wear a self-contained breathing apparatus in
pressure-demand, MSHA/NIOSH (approved or equivalent), and full
protective gear. During a fire, irritating and highly toxic gases
may be generated by thermal decomposition or combustion.
Extinguishing Media:
In case of fire, use water, dry chemical, chemical foam, or
alcohol-resistant foam. Water or foam may cause frothing.
Flash Point: Not available.
Autoignition Temperature: 336 deg C ( 636.80 deg F)

NFPA Rating:
(estimated) Health: 1; Flammability: 1; Instability: 0
Section 6 - Accidental Release Measures
|
General Information: Use proper personal protective equipment as indicated
in Section 8.
Spills/Leaks:
Clean up spills immediately, observing precautions in the Protective
Equipment section. Avoid generating dusty conditions. Provide
ventilation. Cover with dry earth, dry sand, or other non-combustible
material followed with plastic sheet to minimize spreading and
contact with water.
Section 7 - Handling and Storage
|
Handling:
Wash thoroughly after handling. Remove contaminated clothing and
wash before reuse. Minimize dust generation and accumulation. Do not
get in eyes, on skin, or on clothing. Do not ingest or inhale. Use
only in a chemical fume hood.
Storage:
Store in a tightly closed container. Store in a cool, dry,
well-ventilated area away from incompatible substances.
Section 8 - Exposure Controls, Personal Protection
|
Engineering Controls:
Facilities storing or utilizing this material should be equipped
with an eyewash facility and a safety shower. Use adequate
ventilation to keep airborne concentrations low.

|
Ecotoxicity:
No data available.
No information available.
Environmental:
Estimated BCF value = 15 (using a measured water solubility of
690mg/L and a regression-derived equation) This value suggests that
bioconcentration in aquatic organisms is low.Approximate Koc value =
120 (using a measured water solubility of 690 mg/L and a
regression-derived equation) This value suggests that dehydroacetic
acid is expected to have high mobility in soil and is not expected
to absorb in suspended solids and sediment in the water column.

No information available.
Other:
No information available.
Section 13 - Disposal Considerations
