SECTION 4: First-aid measures

4.1 Description of necessary first-aid measures

General advice Get medical advice/ attention if you feel unwell.

If inhaled Not a likely route of exposure. In case of exposure to nuisance dust: Remove person to fresh air and keep comfortable for breathing. Call a poison center or doctor if you feel unwell.

In case of skin contact Wash with water. Call a poison center or doctor if irritation develops or

In case of eye contact Not a likely route of exposure. In case of exposure to nuisance dust: Rinse
cautiously with water for several minutes. Remove contact lenses, if present and easy to do. Continue rinsing. Call a poison center or doctor if you feel unwell.

If swallowed Not a likely route of exposure. Call a poison center or doctor if you feel unwell.
If vomiting occurs naturally, have victim lean forward to reduce the risk of aspiration. Do NOT induce vomiting unless directed to do so by medical personnel. Never give anything by mouth to an unconscious person.

Hazardous combustion products: Carbon oxides, nitrogen oxides.

5.3 Special protective actions for fire-fighters
Wear self-contained breathing apparatus for firefighting if necessary.

Further information
The flammability characteristic of polyimide film is reported as self-extinguishing. Cirlex® chars but does not burn in air. Cirlex® will burn in an atmosphere of 100% oxygen.

SECTION 6: Accidental release measures

6.1 Personal precautions, protective equipment and emergency procedures
Wear suitable personal protective equipment to prevent any contamination of skin, eyes and personal clothing. For personal protection see section 8. Avoid breathing dust, gas, mist, vapors, or spray. Ensure adequate ventilation. Be aware of slipping hazard.

6.2 Environmental precautions
Do not allow to enter drains or waterways.

6.3 Methods and materials for containment and cleaning up
Stop leak if you can do it without risk. Sweep up and shovel into suitable containers for disposal.

Reference to other sections
For disposal see section 13.

SECTION 7: Handling and storage

7.1 Precautions for safe handling
The processing of polyimide films can cause the generation of static charge. Keep the product away from flammable materials. Observe good industrial hygiene practices when handling the product. Do not eat, drink or smoke while handling. Wash hands with soap and water after handling.

7.2 Conditions for safe storage, including any incompatibilities
Keep in a dry and well-ventilated place. Store away from flammable materials.

Specific end use(s)
Apart from the uses mentioned in section 1 no other specific uses are stipulated.
