### 4. FIRST AID MEASURE S

Inhalation: Remove to fresh air. In case of shortness of breath, give oxygen. Immediate medical

attention is required.

Skin contact: Take off all contaminated clothing immediately. Wash off immediately with soap and

plenty of water. If skin irritation persists, call a physician. Wash contaminated clothing before re

- use.

Do not take clothing home to be laundered.

Eye contact: Rinse immediately with plenty of water for at least 15 minutes. If eye irritation persists,

consult a specialist.

Ingestion: Never give anything by mouth to an unconscious person. Do NOT induce vomiting. Drink 1

or 2 glasses of water. Call a physician immediately. If a person vomits when lying on his back, place

him in the recovery position.

Notes to physician

Bronchia l constriction may develop after extensive exposure to isocyanates, even in individuals who

have not been shown tobe previously sensitized.



### 5. FIRE

- FIGHTING MEASURES

Flash point >93 °C ( 199.94 °F ) Method Not Specified

Specific hazards during fire fighting: Do not allow run

- off from fire fighting to enter drains or water

courses. Closed containers may explode when heated or contents contaminated with water.

Special protective equipment for fire

- fighters: In the event of fire, wear self

- contained breathing

apparatus.

Further information: Fire residues and contaminated fire extinguishing water must be disposed of in

accordance with local regulations.

Collect contaminated fire extinguishing water separately. This must not be discharged into drains.



### 6. ACCIDENTAL RELEAS E MEASURES

Personal precautions

Ventilate the area.

Refer to protective measures listed in sections 7 and 8.

MATERIAL IS A POTENTIAL SENSITIZER.L75

### Environmental precautions

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

Do not contaminate surface water.



### Methods for cleaning up

Ventilate the area.

Evacuate personnel to safe areas.

Floor may be slippery; use care to avoid falling.

Contain spills immediately with inert materials (e.g., sand, earth).

Transfer liquids and solid diking material to separate suitable containers for recovery or disposal.

Additional advice: No conditions to be specially mentioned.



### 7. HANDLING AND STOR AGE

Handling

Avoid contact with skin and eyes. For personal protection see section 8. CONTAINERS MAY BE

HAZARDOUS WHEN EMPTY. Since emptied containers retain product residue follow all MSDS and

label warnings even after container is emptied.



### Storage

Storage conditions: Keep container tightly cl osed in a dry and well

- ventilated place.

Further information:

This material is a potential skin sensitizer. See SECTION 8, Exposure Controls/Personal Protection,

prior to handling.
