### 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 per sists,

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 po sition.

Notes to physician: Bronchial constriction may develop after extensive exposure to isocyanates, even

in individuals who have not been shown to be previously sensitized.



### 5. FIRE

- FIGHTING MEASURES

Flash point >93 °C ( 199.9 °F )

Lower explosion l imit not applicable

Upper explosion limit not applicable

Suitable extinguishing media: Foam

Carbon dioxide (CO2)

Dry powder

Thermal decomposition During a fire, irritating and highly toxic gases and/or fumes may be

generated during combustion or decomp osition.

Combustion Products: Hydrogen Cyanide

Carbon monoxide

Carbon dioxide

Nitrogen oxide (NO2)

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 sect ions 7 and 8.

MATERIAL IS A POTENTIAL SENSITIZER.MOR

- FREE L 75

- 275/BASE BULK

Page 4 of 8 Revision date 08/26/2011 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.

F loor 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 closed 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.

- rubber Gloves should be removed and

replaced immediately if there is any indication of degradation or chemical breakthrough.

Before removing gloves clean them with soap and water. NOTE: Material is a possible

skin sensitizer.

Other protection: Avoid all skin contact. Selection of specific personal protective

equipment such as long sleeves, safety glasses with side shields, face shield, safety

shoes, boots, apron, or full body suit will depend on the task.

Respiratory protection: A respiratory protection program meeting OSHA 1910.134 and ANSI

Z88.2 requirements or equivalent must be followed whenever workplace conditions warrant a

respirator ‟ s use. None required if airborne concentrations are ma intained below the exposure

limit listed in Exposure Limit Information. Above the exposure limit: Wear a properly fitted

NIOSH approved (or equivalent) self

- contained breathing apparatus in the pressure demand

mode, OR full

- facepiece, airline respirator in the pressure demand mode with emergency

escape provision.
