4. FIRST AID MEASURES

General advice

: When symptoms persist or in all cases of doubt seek medical advice.

Inhalation

: Move to fresh air in case of accidental inhalation of fumes from overheating or combustion. Consult a physician.

Skin contact

: Wash off with soap and water. Cool skin rapidly with cold water after contact with hot polymer. Do not peel polymer from the skin. Consult a physician if necessary.

Eye contact

: Hold eyelids apart and flush eyes with plenty of water for at least 15 minutes. Get medical attention.

Ingestion

: If victim is conscious: Drink water as a precaution. Consult a physician.

5. FIREFIGHTING MEASURES

Suitable extinguishing media

: Carbon dioxide (CO2), Foam, Water, Dry chemical

Specific hazards during firefighting

: Burning produces noxious and toxic fumes.

Special protective equipment for firefighters

: Wear self-contained breathing apparatus and protective suit. Wear neoprene gloves during cleaning up work after a VITON

® fire.

Further information

: Evacuate personnel to safe areas. Do not allow run-off from fire fighting to enter drains or water courses. The solid polymer can only be burned with difficulty.

6. ACCIDENTAL RELEASE MEASURES

Personal precautions

: Ventilate the area. Refer to protective measures listed in sections 7 and 8.

Environmental precautions

: Try to prevent the material from entering drains or water courses.

Methods for cleaning up

: Shovel into suitable container for disposal. Clean contaminated floors and objects thoroughly while observing environmental regulations.

7. HANDLING AND STORAGE

Handling

Advice on safe handling

: Protect from contamination. Provide appropriate exhaust ventilation at dryers, machinery and at places where dust or volatiles can be generated. In case of insufficient ventilation, wear suitable respiratory equipment.

Advice on protection against fire and explosion

: General precaution for all plastics and elastomers: Take necessary action to avoid static electricity discharge (which might cause ignition of organic vapours). Avoid dust formation.

Storage

SAFETY DATA SHEET



3/8

Requirements for storage areas and containers

: Keep in a dry, cool and well-ventilated place. Keep containers dry and tightly closed to avoid moisture absorption and contamination.

Respiratory protection : In case of insufficient ventilation, wear suitable respiratory equipment. Respirator with combination filter for vapour/particulate (EN 141).

Hand protection : Material: Nitrile rubber Glove thickness: 0.38 mm Wearing time: 8 h If VITON

® is used above 315°C the surface may contain hydrogen fluoride

condensate which may cause severe burns. In this case wear neoprene gloves.

Wear neoprene gloves to prevent contact with hydrofluoric acid.

Skin should be washed after contact.

Eye protection

: Safety glasses with side-shields

Skin and body protection

: If there is a potential for contact with hot/molten material wear heat resistant clothing and footwear.

Hygiene measures

: Do not breathe dust. Do not breathe fumes evolved from hot polymer. General precaution for all plastics and elastomers: Wash hands before breaks and immediately after handling the product. Regular cleaning of equipment, work area and clothing. When using do not eat, drink or smoke.
