Inhalation
Take off immediately all contaminated clothing. Rinse skin with water/shower. If skin irritation
occurs: Get medical advice/attention. Wash contaminated clothing before reuse.
Skin contact
Immediately flush eyes with plenty of water for at least 15 minutes. Remove contact lenses, if
present and easy to do. Continue rinsing. Get medical attention if irritation develops and persists.
Eye contact
Call a physician or poison control center immediately. Rinse mouth. Do not induce vomiting. If
vomiting occurs, keep head low so that stomach content doesn’t get into the lungs.

Provide general supportive measures and treat symptomatically. Thermal burns: Flush with water
immediately. While flushing, remove clothes which do not adhere to affected area. Call an
ambulance. Continue flushing during transport to hospital. Keep victim under observation.
Symptoms may be delayed.
Indication of immediate
medical attention and special
treatment needed
Take off all contaminated clothing immediately. IF exposed or concerned: Get medical
advice/attention. If you feel unwell, seek medical advice (show the label where possible). Ensure

themselves. Wash contaminated clothing before reuse.
General information
5. Fire-fighting measures
Water fog. Alcohol resistant foam. Dry chemical powder. Carbon dioxide (CO2).Suitable extinguishing media
Do not use water jet as an extinguisher, as this will spread the fire.Unsuitable extinguishing
media
Vapors may form explosive mixtures with air. Vapors may travel considerable distance to a source
of ignition and flash back. During fire, gases hazardous to health may be formed.
Specific hazards arising from
the chemical
Self-contained breathing apparatus and full protective clothing must be worn in case of fire.Special protective equipment
and precautions for firefighters

Use standard firefighting procedures and consider the hazards of other involved materials.Specific methods
Flammable liquid and vapor.General fire hazards
6. Accidental release measures
Keep unnecessary personnel away. Keep people away from and upwind of spill/leak. Eliminate all
ignition sources (no smoking, flares, sparks, or flames in immediate area). Wear appropriate
protective equipment and clothing during clean-up. Do not breathe mist or vapor. Do not touch
damaged containers or spilled material unless wearing appropriate protective clothing. Ventilate
closed spaces before entering them. Local authorities should be advised if significant spillages
cannot be contained. For personal protection, see section 8 of the SDS.
Personal precautions,
protective equipment and
emergency procedures
Eliminate all ignition sources (no smoking, flares, sparks, or flames in immediate area). Keep
combustibles (wood, paper, oil, etc.) away from spilled material. Take precautionary measures
against static discharge. Use only non-sparking tools. This material is classified as a water
pollutant under the Clean Water Act and should be prevented from contaminating soil or from
entering sewage and drainage systems which lead to waterways.
Large Spills: Stop the flow of material, if this is without risk. Dike the spilled material, where this is
possible. Use a non-combustible material like vermiculite, sand or earth to soak up the product
and place into a container for later disposal. Following product recovery, flush area with water.
Small Spills: Absorb with earth, sand or other non-combustible material and transfer to containers
for later disposal. Wipe up with absorbent material (e.g. cloth, fleece). Clean surface thoroughly to
remove residual contamination.
Never return spills to original containers for re-use. Put material in suitable, covered, labeled
containers. For waste disposal, see section 13 of the SDS.
Methods and materials for
containment and cleaning up
Avoid release to the environment. Inform appropriate managerial or supervisory personnel of all
environmental releases. Prevent further leakage or spillage if safe to do so. Avoid discharge into
drains, water courses or onto the ground.
Environmental precautions
7. Handling and storage
Obtain special instructions before use. Do not handle until all safety precautions have been read
and understood. Do not handle, store or open near an open flame, sources of heat or sources of
ignition. Protect material from direct sunlight. When using do not smoke. Explosion-proof general
and local exhaust ventilation. Take precautionary measures against static discharges. All
equipment used when handling the product must be grounded. Use non-sparking tools and
explosion-proof equipment. Avoid contact with eyes, skin, and clothing. Avoid prolonged exposure.
Should be handled in closed systems, if possible. Wear appropriate personal protective
equipment. Wash hands thoroughly after handling. Avoid release to the environment. Observe
good industrial hygiene practices.
Precautions for safe handling
Store locked up. Keep away from heat, sparks and open flame. Prevent electrostatic charge
build-up by using common bonding and grounding techniques. Store in a cool, dry place out of
direct sunlight. Store in tightly closed container. Store in a well-ventilated place. Keep in an area
equipped with sprinklers. Store away from incompatible materials (see Section 10 of the SDS).

Explosion-proof general and local exhaust ventilation. Good general ventilation should be used.
Ventilation rates should be matched to conditions. If applicable, use process enclosures, local
exhaust ventilation, or other engineering controls to maintain airborne levels below recommended
exposure limits. If exposure limits have not been established, maintain airborne levels to an
acceptable level. Provide easy access to water supply and eye wash facilities.
Appropriate engineering
controls
Individual protection measures, such as personal protective equipment
Wear safety glasses with side shields (or goggles).Eye/face protection
Skin protection
Wear appropriate chemical resistant gloves. Rubber gloves, butyl rubber, neoprene or PVC gloves
are recommended.
