Unsuitable extinguishing media:

Water spray, 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. 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 upFor 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

Causes skin irritation
Since there is a description that all amyl acetate compounds
including this substance were irritating to the skin, it wasclassified into category 2. Besides, there is a report that after
repeated occlusive application of a 20% solution of this substanceto 197 human subjects, no irritation was observed. In addition,
there is a report that slight irritation was observed after
application of an isomer mixture containing this substance to theears of rabbits, and there is a description that after a 4-hour
non-occlusive application of 0.5 mL of an isomer mixture torabbits, moderate erythema and slight edema were observed, andslight desquamation was observed 7 days after application.
Causes serious eye irritation
Although there was no specific data, there are descriptions that
this substance was irritating to the eyes, and that isomers of thissubstance were irritating to the eyes. From the above results, itwas classified into category 2A.
Classification not possible
Classification not possible
Classification not possible
There was no in vivo data. As for in vitro, it was negative inbacterial reverse mutation tests, a mouse lymphoma assay and achromosomal aberration test with cultured mammalian cells.
Classification not possible
Classification not possible
May cause drowsiness or dizziness
May cause respiratory irritation
This substance was irritating to the respiratory tract. In humans,
on inhalation exposure, headache, weakness and central nervous
system depression, and at the high concentration unconsciousnesswere observed, and as for experimental animals, on exposure to thissubstance or the isomer mixtures, central nervous system depression
such as narcotic effects, labored breathing, ataxia and loss ofrighting reflex in rats and mice, etc. were observed. From theabove, it was classified into category 3 (respiratory tract
irritation, narcosis).

STOT-repeated exposure:

Causes damage to organs (optic nerve) through prolonged or repeatedexposure
Although there are no reports in either humans or experimental
animals in which the effects by repeated exposure to this substanceitself were made clear, there were the following findings regarding
the effects by exposure to isomer mixtures containing thissubstance. In humans, there is a report that irritation to the eyes
and photophobia were observed in workers exposed to pentyl acetate(details unknown) for 1 month-30 years. In addition, 30 workers whoengaged in film production and were exposed to pentyl acetate
mixtures (details unknown) at concentrations of 3,700-14,800 ppm,
complained of sensitivity to light, conjunctival irritation andlacrimation at work, and in 4 of them who engaged for 4-9 years,
the symptoms were severe, and narrowing of the field of vision andatrophic changes of the visual nerve were observed. As forexperimental animals, there is a description that degeneration of
the optic nerve was observed in a test in which rabbits wereexposed by inhalation to a pentyl acetate mixture (details unknown)
at 7,500 ppm for 60 days, therefore, it was considered a findingthat supported effect on the optic nerve in humans. From the above,
this substance was also classified into category 1 (optic nerve) as
well as other isomers since disorder of the optic nerve wasobserved in pentyl acetate mixtures.
