Hazards/Toxicity
|
Type: |
Acute toxicity and flammability |
Toxicity: |
Vapors irritate the eyes, nose,
and throat. Inhalation causes an anesthetic effect. |
|
Emergency Measures
|
Eye contact: |
Immediately rinse eye(s)
under running water for 15 minutes or more, and then seek medical
attention. |
Skin contact: |
Take off contaminated clothing,
and then rinse the affected site with a large quantity of water.
Seek medical attention for any skin inflammation. |
Inhalation: |
Immediately move affected
people to an area of fresh air, keep them still and warm, and
seek medical attention as soon as possible. Perform CPR if breathing
stops. |
Ingestion: |
Seek immediate medical attention.
If the affected person is unconscious, do not attempt to administer
anything orally or induce vomiting. |
|
Fire-Fighting Measures
|
Method: |
Cut off the fuel source from
the fire, and then put out with an extinguishing agent. To ensure
that the fire does not spread, spray water on surrounding tanks
and the building to cool them down. Fight the fire from an upwind
position, and use a respirator when necessary. |
Extinguishing
agent: |
Water, powder, carbon dioxide,
and alcohol foam are all effective. |
|
Leakage Measures
|
- Remove anyone downwind
of the leak. Cordon off the leakage site with a rope or other
means to prevent anyone from entering. Promptly remove any ignition
sources nearby. Always wear protective equipment during cleanup
work. Do not perform cleanup work downwind of the leak.
- If only a small amount
leaked, soak it up with dirt, sand, or other such materials,
collect it into an empty container, and then rinse with a large
quantity of water.
- For major leaks, stop
the flow with dirt, sand, or other such materials. After guiding
the flow into a safe location, cover the surface of the liquid
with foam or other such agent, and then collect as much as possible
into empty containers. Finally, rinse with a large quantity of
water, making sure that the concentrated liquid does not get
into rivers or other bodies of water.

Precautions on Handling
and Storage
|
Handling: |
- Use appropriate protective
equipment to ensure that the chemical is not inhaled and does
not come in contact with the eyes, skin, or clothing. Work upwind
from the chemical whenever possible.
- Tightly seal containers
or install a local exhaust system.
- Avoid objects with high
temperatures, sparks, and flames. Avoid contact with strong oxidizing
agents.
- Take anti-static measures,
and use work clothes and work boots that are conductive.
- Do not handle in a manner
in which containers will fall over, drop, be exposed to impacts,
or dragged along a surface.
- Once the chemical is used
up, collect empty containers at a single location.
|
Storage: |
- Make sure all electrical
equipment used in the storage area is of explosion-proof construction,
and make sure all equipment is grounded.
- Do not place containers
in direct sunlight. Store in cool, dark location.
- Do not place near combustible
material or heat sources such as boilers.
- Do not place in the same
location as oxidizing substances or organic peroxides.

Measures for Preventing
Exposure
|
Controlled concentration: |
400ppm |
Permissible concentration: |
Japanese Association of Industrial
Health recommended value (1995): |
400ppm |
ACGIH (TLV) (1995-96): |
TWA 400ppm |
OSHA (PEL) (1995): |
400ppm |
|
Facility measures: |
- When using in indoor workplaces,
seal the source or install a local exhaust system.
- Install a safety shower
and a place to wash hands and eyes near location where chemical
will be handled. Make the location of these clear to all.
|
Protective equipment: |
Depending on the situation,
use organic gas mask, air masks, respirators, protective goggles,
protective gloves, and protective boots. |

Fire/Explosion Hazard
Data
|
Flash point:
|
-4°C |
Ignition point:
|
427°C |
(Stability and reactivity)
Explosive range from 2.2 to 11.0 vol.% |
Vapors are heavier than air
and tend to collect low to the ground, sometime generating an
explosive mixture with the potential of igniting from a long
distance. |

secondary anemia, increased leukocyte counts, visceral edema,
and fatty degeneration. |
|

Precautions when Transporting
|
- The sender should give
special instructions on shipping to the shipper when transporting
the chemical by vehicle or other means.
- During transport, care
must be taken so that containers do not leak, fall over, drop,
or otherwise become damaged.
- All relevant laws including
the Fire Service Law and Substances Control Law must be obeyed.

|
- Dispose of by incineration.
Employ any of the following methods:
- Spray chemical into the
incinerator fire chamber and incinerate it.
- When there is only a small
quantity, soak up with silious earth or similar material, and
then incinerate using an open incinerator.
- Wastewater containing
