 4. First-aid measures
Inhalation Remove victim to fresh air and keep at rest in a position comfortable for breathing. Call a poison
center or doctor/physician if you feel unwell.
Skin contact Take off immediately all contaminated clothing. Rinse skin with water/shower. Call a physician or
poison control center immediately. Chemical burns must be treated by a physician. Wash
contaminated clothing before reuse.
Eye contact Immediately flush eyes with plenty of water for at least 15 minutes. Remove contact lenses, if
present and easy to do. Continue rinsing. Call a physician or poison control center immediately.
Ingestion 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.
Most important Burning pain and severe corrosive skin damage. Causes serious eye damage. Symptoms may
symptoms/effects, acute and include stinging, tearing, redness, swelling, and blurred vision. Permanent eye damage including
delayed blindness could result. May cause respiratory irritation.
Indication of immediate Provide general supportive measures and treat symptomatically. Chemical burns: Flush with water
medical attention and special immediately. While flushing, remove clothes which do not adhere to affected area. Call an
treatment needed ambulance. Continue flushing during transport to hospital. Keep victim under observation.
Symptoms may be delayed.
General information If you feel unwell, seek medical advice (show the label where possible). Ensure that medical
personnel are aware of the material(s) involved, and take precautions to protect themselves.

5. Fire-fighting measures
Suitable extinguishing media Water fog. Foam. Dry chemical powder. Carbon dioxide (CO2).
Unsuitable extinguishing Do not use water jet as an extinguisher, as this will spread the fire.

6. Accidental release measures

Personal precautions, Keep unnecessary personnel away. Keep people away from and upwind of spill/leak. Wear
protective equipment and appropriate protective equipment and clothing during clean-up. Do not breathe mist/vapors. Do not
emergency procedures touch damaged containers or spilled material unless wearing appropriate protective clothing.
Ensure adequate ventilation. Local authorities should be advised if significant spillages cannot be
contained. For personal protection, see section 8 of the SDS.
Methods and materials for Large Spills: Stop the flow of material, if this is without risk. Dike the spilled material, where this is
containment and cleaning up possible. Absorb in vermiculite, dry sand or earth and place into containers. Following product
recovery, flush area with water.

Small Spills: 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. For waste disposal, see section 13 of the SDS.
Environmental precautions Avoid discharge into drains, water courses or onto the ground.

7. Handling and storage

Precautions for safe handling Do not breathe mist/vapors. Do not get in eyes, on skin, or on clothing. Avoid prolonged exposure.
Provide adequate ventilation. Wear appropriate personal protective equipment. Observe good
industrial hygiene practices.
Conditions for safe storage, Store locked up. Store in tightly closed container. Store away from incompatible materials (see
including any incompatibilities Section 10 of the SDS).
