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. Remove all sources of ignition. Keep away
personnel except for authorized ones from spillage area by
stretching ropes.

:

Attention should be given to avoid damage to the environment byflowing of spillage to rivers.

Environmental precautions
Environmental precautions

Methods and Equipment for Containment and Cleaning up
For containment:

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.

No classification
There are reports that after application of this substance (99.6%)
to rabbits for 4 hours, no irritative reaction was observed andscores of eschar formation and edema were both 0, and that noirritation was observed in a test with guinea pigs. In addition,
there is a report that it was not irritating in a patch test by 48hour occlusive application of 4% of this substance to volunteers.
Causes eye irritation
There is a report that after application of 0.1 mL of thissubstance to the eyes of rabbits, slight to moderate iritis wasobserved but this disappeared after 48 hours, and there weremultiple results with mild irritation or no irritation in other eye
irritation tests with rabbits. In addition, there is a report thatvery slight irritation was observed in volunteers exposed to thissubstance (70-1400 mg/m3). From the above results, it wasclassified into category 2B.
Classification not possible
Classification not possible
Classification not possible due to lack of data. Besides, although
there are reports that no sensitization was observed in a test withguinea pigs or in an ear swelling test with mice, and there is adescription no sensitization was observed in humans, since detailsof the test methods and results were unknown, the data were judged
to be inadequate for classification.
Classification not possible
There are no in vivo data. As for in vitro, it was negative inbacterial reverse mutation tests and a chromosomal aberration testwith cultured mammalian cells.
Classification not possible
Classification not possible
No effects on the developmental toxicity and fertility in female
animals were observed. However, since the information on thefertility in male animals was not sufficient, it was classified as"Classification not possible."
May cause drowsiness or dizziness
May cause respiratory irritation
In humans, headache and nausea by inhalation exposure of thevapour, and dizziness, dyspnea, unconsciousness and weakness athigh concentrations were reported. As for experimental animals,ataxia, forced respiration and narcotic effects by an inhalation
exposure of rats at 1.3 mg/L, dyspnea as well as these symptoms byan inhalation exposure of rats at 32.6 mg/L were observed. Symptoms
such as coordination ataxia reported in an inhalation exposure ofrats were considered to be due to narcotic effects of thissubstance. From the above, this substance was judged to have
respiratory tract irritation and narcotic effects, and it wasclassified into category 3 (respiratory tract irritation,narcosis).

STOT-repeated exposure:Classification not possible
As for experimental animals, in a study in which rats were exposedby inhalation to this substance for 13 weeks, only effects on therespiratory organs were observed at high concentrations
corresponding to "Not classified". In addition, there is adescription that also in a test in which guinea pigs were exposedby inhalation to this substance for 28 days, no effects wereobserved in a hematological test, urine examinations andpathological examination at 4840 mg/m3. However, there was notoxicity information through other routes and findings in humans,
therefore, it was classified as "Classification not possible" dueto lack of data.
