symptoms/effects, acute anddelayedHeadache. Nausea, vomiting. Coughing.

Indication of immediate
medical attention and special
treatment needed

Treat symptomatically.

General information

Ensure that medical personnel are aware of the material(s) involved, and take precautions toprotect themselves.

5. Fire-fighting measures
Suitable extinguishing media

Water fog. Foam. Dry chemical powder. Carbon dioxide (CO2).

Unsuitable extinguishingmedia

Do not use water jet as an extinguisher, as this will spread the fire.

Specific hazards arising fromthe chemical

During fire, gases hazardous to health may be formed.

Special protective equipment
and precautions for firefighters

Self-contained breathing apparatus and full protective clothing must be worn in case of fire.

Fire fighting
equipment/instructions

Use water spray to cool unopened containers.

Specific methods

Use standard firefighting procedures and consider the hazards of other involved materials.

General fire hazards

No unusual fire or explosion hazards noted.

6. Accidental release measures
Personal precautions,protective equipment andemergency procedures
Methods and materials forcontainment and cleaning up

Environmental precautions

Keep unnecessary personnel away. Keep people away from and upwind of spill/leak. Wearappropriate protective equipment and clothing during clean-up. Ensure adequate ventilation. Local
authorities should be advised if significant spillages cannot be contained. For personal protection,
see section 8 of the SDS.
The product is immiscible with water and will spread on the water surface. This material isclassified as a water pollutant under the Clean Water Act and should be prevented fromcontaminating soil or from entering sewage and drainage systems which lead to waterways. Stop
the flow of material, if this is without risk. Following product recovery, flush area with water. For
waste disposal, see section 13 of the SDS.
Avoid release to the environment. Inform appropriate managerial or supervisory personnel of allenvironmental releases. Prevent further leakage or spillage if safe to do so. Avoid discharge intodrains, water courses or onto the ground.

7. Handling and storage
Precautions for safe handling
Conditions for safe storage,
including any incompatibilities

Provide adequate ventilation. Wear appropriate personal protective equipment. Avoid release tothe environment. Observe good industrial hygiene practices.
Store in tightly closed container. Store away from incompatible materials (see Section 10 of theSDS).

applicable, use process enclosures, local exhaust ventilation, or other engineering controls tomaintain airborne levels below recommended exposure limits. If exposure limits have not been
established, maintain airborne levels to an acceptable level.

Individual protection measures, such as personal protective equipment
Wear safety glasses with side shields (or goggles).
Eye/face protection
Skin protection
Hand protection
Other

Wear appropriate chemical resistant gloves.
Wear suitable protective clothing.

Respiratory protection

In case of insufficient ventilation, wear suitable respiratory equipment.

Thermal hazards

Not applicable.

General hygiene
considerations

Always observe good personal hygiene measures, such as washing after handling the material
and before eating, drinking, and/or smoking. Routinely wash work clothing and protective
equipment to remove contaminants.
