First Aid Measures
IF INHALED:

Remove person to fresh air and keep comfortable for breathing.
Call a POISON CENTER/doctor, if you feel unwell.

IF ON SKIN:

Take off immediately all contaminated clothing.
Rinse for at least 15 minutes with lukewarm slowly flowing water.
If skin irritation occurs, get medical advice/attention.
Wash contaminated clothes before reuse.

IF IN EYES:

Rinse cautiously with water for several minutes. Remove contact lenses, if
present and easy to do. Continue rinsing. Rinse for at least 15 minutes, and thenget medical attention.

IF SWALLOWED:

Call a POISON CENTER/doctor, if you feel unwell.
If the product remains in the mouth, rinse thoroughly.
Do NOT induce vomiting.

Most Important Signs andSymptoms, Acute andDelayed:Inhaled: hypesthesia, headache
Skin: dry skinEyes: redness, pain
Ingested: gastrospasm, burning sensation, nausea and vomiting

Extinguishing Media:

Small fire: Carbon dioxide, powder extinguisher, water sprinkling and foam
extinguisher.
Large fire: Water sprinkling, sprayed water and foam extinguisher

Inappropriate Extinguishing
Media

:

Straight stream of waterSpecific Hazards:

May explode if aerosol container is at the scene of a fire.
Extremely flammable and easily ignited by heat, spark and flame.
May cause vapor-explosion indoors, outdoors or in a sewage trench.
May generate irritant, poisonous, or corrosive gas in a fire.

Special Firefighting
Procedures:

Extremely low flash point: Use water if other extinguishing media are noteffective.
Remove containers from the fire area, if it can be done safely.
If not, spray containers and the surrounding area with water to keep them cool.
Conduct firefighting activities from the most distant place that allows it to bedone effectively using an unmanned hose holder or a nozzle with a monitor.
Keep cooling containers with plenty of water even after the fire is extinguished.

Protection of Firefighters

6.

SDS15118-08e:

Wear appropriate protective equipment to avoid inhalation of toxic gases.
Fight a fire from upwind.

Personal Precautions,Protective Equipment andEmergency Procedures:

Operators must wear proper protective gear (refer to 8. Exposure
Controls/Personal Protection) and avoid contact with the eyes and skin, and gas
inhalation.
When leaking (spraying), handle from upwind. Keep the leaking spot facing up.
Let the gas spray out completely and then perform the subsequent procedures.
Quickly remove nearby ignition sources, high-temperature objects andflammables. Evacuate anyone who is downwind and keep everyone out except
authorized persons.
Ventilate before entering the restricted area.

Environmental Precautions:

Avoid draining to drainage trench, sewage trench, basement or a closed space.
Be careful not to discharge into rivers or anywhere else that would affect theenvironment.

Method and Materials for
Containment andCleaning Up:

Use tools whose materials do not generate sparks upon impact or due to static
electricity.
For small leaks, collect the material by absorbing the released material with soil,
sand, or non-combustible material.
For large leaks, put sand around the leakage to keep it from flowing out.
Process contaminated items and waste according to relevant regulations.

:

Inform relevant organizations immediately to prevent further accidents andexpansion.
Remove nearby potential ignition sources immediately and prepare fire
extinguishing media.
Do not walk on the released material unnecessarily.

Technical Measures:

Amounts larger than the designated amount must be handled in a factory, astorage facility, or a laboratory in compliance with the standards required by therelevant regulations.
Connect the equipment to ground and use explosion-proof electric appliances as
an anti-static measure.
Do not use high-temperature objects, sparks and fire nearby. - No smoking.
Take engineering measures and use protective equipment as described in
Section 8. Exposure Controls/Personal Protection.
Provide local and general ventilation as described in Section 8. Exposure
Controls/Personal Protection.

Precautions for Safe
Handling:

Do not use things that generate fire, sparks and arcs or high-temperature objects.
Do not spray at an open flame or high-temperature incandescent objects.
Use this substance with one's back facing upwind to prevent it from being
blown back on the user.
The container may rupture if stored in a high-temperature place.
Avoid contact, inhalation, or ingestion. Do not get in eyes. Wash hands
thoroughly after handling.
